Every year, thousands of Philippine businesses face the same challenge: their instruments are due for calibration, and they need to choose a calibration service provider. For some, it is a routine decision — they have a trusted provider they have used for years. For others — particularly businesses setting up a calibration program for the first time, businesses that have had problems with their current provider, or businesses whose auditor has flagged their calibration certificates as non-compliant — it is a decision that carries real consequences.
Choose the right calibration laboratory and you get certificates that pass every audit, satisfy every regulator, and give you genuine confidence in your measurement data. Choose the wrong one and you may discover the problem at the worst possible moment — during an ISO 9001 surveillance audit, an FDA Philippines inspection, an IATF 16949 third-party assessment, or a customer quality review.
This guide is designed to make that decision straightforward. It covers everything you need to evaluate a calibration laboratory in the Philippines — the credentials to require, the questions to ask, the certificate elements to verify, the red flags to avoid, and the practical checklist you can apply to any provider. And it explains, based on all of these criteria, why Premier Physic Metrologie (PPM Calibration) is the calibration laboratory that Philippine businesses consistently choose and return to.
Section 1: Why Choosing the Right Calibration Lab Matters More Than You Think
The Real Cost of the Wrong Choice
Many Philippine businesses choose their calibration provider based primarily on price. This is understandable — calibration is a recurring cost, and the cheapest option is tempting, especially when all providers seem to offer similar services. But the assumption that all calibration certificates are equivalent is fundamentally wrong, and it is a misconception that costs Philippine businesses significantly each year.
Consider what happens when a Philippine food manufacturer is inspected by FDA Philippines and presents calibration certificates from an unaccredited provider. The inspector reviews the certificates and notes: no measurement uncertainty values, no traceability statement, no PAB-DAP accreditation mark. This is a GMP finding — a documented deficiency that requires corrective action, may result in a warning letter, and can trigger more frequent inspections.
Or consider the ISO 9001 certified manufacturer whose surveillance auditor reviews calibration records and finds that the certificates come from a laboratory that is not ISO/IEC 17025 accredited. The auditor raises a major non-conformance under Clause 7.1.5 — the manufacturer cannot prove their measurement results are traceable. Corrective action is required before the next audit. Recertification costs, customer notifications, and internal investigation time follow.
These are not hypothetical scenarios. They happen regularly in the Philippines. The cost of the wrong calibration provider — one audit finding, one FDA inspection failure, one lost export customer — typically exceeds years of savings from choosing a cheaper unaccredited provider.
What Makes a Calibration Lab the Right Choice
The right calibration laboratory for a Philippine business is one that satisfies all of the following:
- Its accreditation is current, genuine, and covers your specific instruments
- Its calibration certificates are technically valid — traceable, with uncertainty data, and signed by a qualified metrologist
- Its capabilities match your instrument types and measurement ranges
- Its service model (laboratory, onsite, or both) fits your operational needs
- Its experience includes your industry and the regulatory requirements you face
- Its support extends beyond issuing certificates — to consultation, training, and after-service follow-up
This guide will take you through each of these criteria in detail — with specific questions to ask, things to verify, and red flags to watch for.
Section 2: The Non-Negotiable — ISO/IEC 17025:2017 Accreditation
Why Accreditation Is the Starting Point, Not One Factor Among Many
Some buyers approach calibration laboratory selection as a multi-factor decision — balancing price, location, turnaround time, accreditation, and reputation. This is a mistake. Accreditation is not one factor among many. It is the threshold requirement. A calibration laboratory that does not hold current ISO/IEC 17025:2017 accreditation from a recognized national accreditation body should not be on your shortlist — regardless of how competitive its prices are, how conveniently located it is, or how professional its marketing materials look.
The reason is simple: without ISO/IEC 17025 accreditation, there is no independent, expert verification that the laboratory is technically competent to produce valid calibration results. The laboratory may have good intentions, trained staff, and a professional appearance — but none of that substitutes for the rigorous on-site technical assessment by qualified metrologists that is the basis of ISO/IEC 17025 accreditation.
What ISO/IEC 17025 Accreditation Requires
ISO/IEC 17025:2017 accreditation requires a laboratory to demonstrate, through independent expert assessment, that it meets all requirements of the standard across five domains:
- Impartiality: The laboratory’s results are not influenced by commercial or other pressures. It reports what its measurements actually show — including out-of-tolerance findings.
- Technical competence: Staff are qualified, reference standards are calibrated and traceable, methods are validated, and facilities provide appropriate environmental conditions.
- Metrological traceability: Every measurement result can be related to national and international measurement standards through an unbroken, documented chain of calibrations.
- Measurement uncertainty: The laboratory calculates and reports measurement uncertainty for every calibration result — quantifying the reliability of each measurement.
- Quality management: A documented quality management system ensures consistent application of all technical and management requirements.
How to Verify Accreditation in the Philippines
In the Philippines, ISO/IEC 17025 accreditation for calibration laboratories is granted by the Philippine Accreditation Bureau (PAB), operating under the Development Academy of the Philippines (DAP) and the Department of Trade and Industry (DTI). To verify a laboratory’s accreditation:
- Request the laboratory’s current PAB-DAP accreditation certificate — check the issue date, expiry date, and certificate number
- Review the scope of accreditation — confirm it covers your specific instrument types and measurement ranges
- Verify the certificate number against the PAB-DAP online directory for independent confirmation
- Check for the ILAC MRA combined mark — confirming international recognition through APLAC and ILAC mutual recognition arrangements
| Critical Warning: Some calibration providers in the Philippines use language like ‘certified,’ ‘ISO compliant,’ ‘accredited-standard,’ or ‘ISO 9001 certified’ to suggest accreditation without actually holding ISO/IEC 17025 accreditation. These terms are not substitutes for ISO/IEC 17025 PAB-DAP accreditation. Always ask specifically: ‘Do you hold current ISO/IEC 17025:2017 accreditation from PAB-DAP?’ and request the certificate. If the answer is no or evasive, do not use that provider for compliance-critical calibration. |
Section 3: The Scope of Accreditation — The Detail That Matters Most
What the Scope of Accreditation Is
The scope of accreditation is a document attached to the laboratory’s accreditation certificate that lists exactly which measurement disciplines, instrument categories, and measurement ranges the laboratory is accredited to calibrate. It is the most practically important document in the accreditation package — more important, in some ways, than the certificate itself.
A laboratory may hold a valid ISO/IEC 17025 accreditation certificate but have a scope that does not cover your specific instruments. For example, a laboratory accredited only for temperature calibration cannot issue an accredited certificate for your pressure gauges. A laboratory accredited for pressure calibration only up to 100 bar cannot issue an accredited certificate for your 300 bar process instruments.
How to Read a Scope of Accreditation
When reviewing a laboratory’s scope of accreditation, look for the following information for each measurement discipline relevant to your instruments:
| Scope Element | What to Check |
| Measurement discipline | Confirm your instrument type is listed — temperature, pressure, electrical, weight, torque, flow, force, volume |
| Instrument category | Verify the specific instrument type is covered — e.g., RTDs (not just thermometers), pressure transducers (not just gauges) |
| Measurement range | Check that your instrument’s operating range falls within the accredited range — e.g., if your oven operates at 300°C, confirm the scope covers that temperature |
| Best measurement uncertainty | Review the uncertainty values — lower uncertainty means higher reference accuracy, which matters for precision applications |
| Method reference | The calibration procedure or standard used — important for pharmaceutical and other regulated applications where specific methods may be required |
PPM Calibration’s Comprehensive Accredited Scope
One of the most significant advantages of working with PPM Calibration is the breadth of its accredited scope — covering all major measurement disciplines required by Philippine industry under a single ISO/IEC 17025:2017 PAB-DAP accreditation:
| Discipline | Instruments Covered | Industries Served |
| Temperature | Thermometers, RTDs, thermocouples, data loggers, ovens, autoclaves, chambers | Food, pharma, semiconductor, manufacturing |
| Pressure & Vacuum | Pressure gauges, transducers, manometers, vacuum gauges, DP instruments | Oil & gas, chemical, pharma, manufacturing |
| Electrical | DMMs, clamp meters, power analyzers, LCR meters, oscilloscopes, insulation testers | Electronics, semiconductor, utilities, manufacturing |
| Weight & Mass | Analytical balances, platform scales, test weights, load cells | Food, pharma, retail, construction |
| Torque | Torque wrenches, screwdrivers, multipliers, testers | Automotive, aerospace, manufacturing |
| Flow | Flow meters, rotameters, mass flow controllers | Water treatment, oil & gas, pharmaceutical |
| Force | Force gauges, dynamometers, compression and tensile testers | Construction, aerospace, materials testing |
| Volume | Pipettes, burettes, volumetric glassware, dispensing systems | Pharma, chemical, food laboratories |
This comprehensive scope means Philippine businesses can consolidate their entire calibration program — across all instrument types — with PPM Calibration. One provider, one accreditation, one set of consistent, high-quality certificates for all their audit and compliance needs.
Section 4: Evaluating Calibration Certificate Quality
The calibration certificate is the primary deliverable of any calibration service. Before committing to a provider, ask for a sample certificate and evaluate it against the requirements of ISO/IEC 17025:2017. A non-compliant certificate will not satisfy your auditors, regardless of what the laboratory claims.
The 10 Elements Every ISO/IEC 17025 Certificate Must Have
- Title: Clearly labeled as a ‘Calibration Certificate’ — not a ‘calibration record,’ ‘service report,’ or ‘test certificate’
- Laboratory identification: Full legal name, address, and PAB-DAP accreditation certificate number
- Client information: Name and contact details of the organization that owns the instrument
- Instrument identification: Make, model, serial number, and tag or asset number
- Date of calibration: The actual date the calibration was performed — not the issue date
- Calibration method: Reference to the specific procedure or standard used
- Traceability statement: Explicit statement linking results to national or international measurement standards through the reference standard chain
- Calibration results: Actual measurement data at each test point — as-found AND as-left readings, not just a pass/fail stamp
- Measurement uncertainty: Expressed as ±X in the relevant unit, with coverage factor (k=2 typical) at each test point — this is non-negotiable
- Authorized signature: Signed and dated by the responsible metrologist — confirming technical review
The Single Most Important Thing to Check: Measurement Uncertainty
Of all ten elements, measurement uncertainty is the most commonly absent from non-compliant certificates and the most important technically. If a calibration certificate does not include measurement uncertainty values at each test point, it does not comply with ISO/IEC 17025:2017 — regardless of any other claims or marks on the document.
Measurement uncertainty tells you how accurate the calibration result itself is. It is the scientific expression of the confidence you can place in the reported measurement. Without it, you cannot properly determine whether your instrument is within acceptable tolerance for its application. And without it, your auditor will correctly identify the certificate as non-compliant.
Ask every prospective calibration provider: ‘Does your calibration certificate include measurement uncertainty values at every test point?’ If the answer is no, or if the provider does not know what measurement uncertainty is, do not use that provider for compliance-critical calibration.
| Real Audit Scenario: An ISO 9001 auditor reviewing calibration records for a Philippine manufacturer found certificates that showed only ‘PASS’ for each instrument — no measurement data, no uncertainty values, no traceability statement. The auditor raised a major non-conformance under Clause 7.1.5. The manufacturer had to replace all calibration certificates with compliant ones from an accredited laboratory — at significant cost and with production disruption. The money saved by using the cheaper unaccredited provider was vastly outweighed by the cost of remediation. PPM Calibration’s certificates always include complete measurement data and uncertainty values on every test point. |
Red Flags on Calibration Certificates
| Red Flag | What It Means |
| No measurement uncertainty values | Certificate does not comply with ISO/IEC 17025:2017. Not acceptable for audit purposes. |
| Only ‘PASS’ or ‘FAIL’ — no measurement data | Not a calibration certificate — a verification record at best. Provides no measurement evidence. |
| No traceability statement | No documented connection to national standards. Results are scientifically unverified. |
| No PAB-DAP accreditation mark | Laboratory is not ISO/IEC 17025 accredited — or the accreditation does not cover this calibration. |
| ISO 9001 logo instead of ISO/IEC 17025 mark | ISO 9001 does not certify measurement competence. Not equivalent to ISO/IEC 17025 accreditation. |
| No authorized metrologist signature | Certificate lacks technical accountability. Who reviewed and approved the results? |
| Certificate date differs from calibration date | May indicate backdated or pre-printed certificates — a quality integrity concern. |
| Unusually fast turnaround for complex instruments | Very fast turnaround may indicate shortcuts in the calibration process. |
| Certificate covers only one test point | Most instruments require multi-point calibration across their measurement range. Single-point is insufficient for most applications. |
Section 5: The 10-Question Checklist for Choosing a Calibration Lab in the Philippines
Use this checklist when evaluating any calibration laboratory. A laboratory that answers all ten questions satisfactorily is one you can trust with your compliance and quality program.
Question 1: Do you hold current ISO/IEC 17025:2017 accreditation from PAB-DAP?
The answer must be yes, and the laboratory must be able to provide a current, unexpired PAB-DAP accreditation certificate upon request. Any answer other than an unambiguous yes, supported by documentation, is disqualifying for compliance-critical calibration.
Question 2: Does your scope of accreditation cover my specific instruments and ranges?
Request the scope of accreditation document and verify that your specific instrument types — including the make and model where possible — and the measurement ranges your instruments operate in fall within the accredited scope. Do not assume coverage — verify it.
Question 3: Do your calibration certificates include measurement uncertainty at every test point?
Request a sample certificate and check for measurement uncertainty values expressed as ±X [unit] with a coverage factor. If the certificate does not include uncertainty values, it is not ISO/IEC 17025 compliant. This question should be asked explicitly because some providers will not volunteer this information.
Question 4: What reference standards do you use, and how are they traceable?
A competent laboratory should be able to explain its traceability chain — that its reference standards were calibrated at ITDI-DOST or at another recognized national metrology institute, and that the calibration certificates for those reference standards are current. If the laboratory cannot explain its traceability chain, its results are not traceable regardless of what it claims.
Question 5: Do you offer both laboratory and onsite calibration?
For Philippine businesses with large instrument inventories or fixed installations, onsite calibration capability is essential. A laboratory that offers only laboratory calibration may not be the right fit for your operational needs. Verify that the onsite calibration service is also covered under the laboratory’s ISO/IEC 17025 accreditation — not just offered as an unaccredited field service.
Question 6: What is your turnaround time for my instrument types?
Calibration turnaround time has real operational implications. Ask for specific turnaround time estimates for your instrument types — not just a general statement. Ask whether rush or priority processing is available for urgent requirements. For large calibration campaigns, ask whether a dedicated schedule can be arranged to coordinate with your production planning.
Question 7: Do you offer instrument repair if instruments are found out of tolerance?
The calibration process sometimes reveals that instruments are significantly out of tolerance and need repair before they can be returned to service. A calibration provider that also offers instrument repair saves you the time, cost, and logistics complexity of managing repair and recalibration through separate vendors. Ask whether repair services are available and whether recalibration after repair is offered.
Question 8: Have you served clients in my industry, and are you familiar with our regulatory requirements?
Industry experience matters in calibration. A laboratory that has calibrated instruments for pharmaceutical manufacturers understands FDA Philippines GMP documentation requirements. A laboratory experienced with automotive clients understands IATF 16949 certificate requirements. Ask for references from clients in your industry, or ask the laboratory to explain the specific regulatory requirements relevant to your sector. A laboratory that cannot speak to your regulatory environment with confidence may not be the right partner.
Question 9: What is your geographic coverage, and can you serve our location?
For Metro Manila and Luzon-based clients, most accredited laboratories can provide service. But for businesses in Cebu, Davao, or other regions, geographic coverage becomes an important consideration. For businesses in PEZA ecozones or industrial parks, ask specifically whether the laboratory regularly serves that location and whether any access or permit requirements have been navigated before.
Question 10: What support do you offer beyond issuing certificates?
The best calibration providers offer more than certificates. Ask about: proactive recalibration reminders, calibration management support for large instrument inventories, consultation on calibration intervals, guidance on out-of-tolerance situations, calibration training for your team, and updates on changes to measurement standards or regulatory requirements that affect your calibration program. These services distinguish a calibration partner from a calibration vendor.
| PPM Calibration answers yes to all ten questions. With 25 years of experience, ISO/IEC 17025:2017 PAB-DAP accreditation, the broadest calibration scope in the Philippines, laboratory and onsite service, instrument repair, free calibration training, and nationwide coverage — PPM Calibration is the calibration partner that Philippine businesses choose when they need to get it right. |
Section 6: Comparing Calibration Providers — Laboratory vs. Laboratory
When evaluating multiple calibration providers, a direct comparison using consistent criteria provides the clearest picture. Here is a framework for comparing calibration laboratories in the Philippines.
The Comparison Framework
| Evaluation Criterion | Accredited Lab (PPM Calibration) | Unaccredited Provider |
| ISO/IEC 17025:2017 accreditation | Yes — PAB-DAP, current and valid | No — not independently assessed |
| Measurement traceability | Fully documented to ITDI-DOST and BIPM | Unknown or unverified |
| Measurement uncertainty on certificates | Yes — required, always included | No — typically absent |
| As-found / as-left data | Yes — complete measurement data | Often absent — only pass/fail |
| Acceptance by ISO 9001 auditors | Yes — fully accepted | Often rejected — major non-conformance risk |
| Acceptance by FDA Philippines | Yes — satisfies GMP requirements | May be challenged or rejected |
| International customer acceptance | Yes — ILAC MRA recognized globally | Not recognized internationally |
| Technical competence | Independently verified by PAB-DAP assessors | Not independently verified |
| Quality of reference standards | Traceable, regularly recalibrated | Unknown or unverified |
| Proficiency testing participation | Required for accreditation | Not required — may not participate |
| Price | Higher — reflects genuine technical cost | Lower — reflects absence of real calibration infrastructure |
| True value | High — certificates usable for all compliance purposes | Low to negative — certificate failure costs dwarf savings |
Section 7: Calibration Lab Selection by Industry — What to Prioritize
Different Philippine industries have different calibration priorities. Here is guidance on what to emphasize when choosing a calibration lab for each major sector.
Manufacturing — ISO 9001 and IATF 16949
For ISO 9001 certified Philippine manufacturers, the most important criterion is that certificates satisfy Clause 7.1.5 — which means ISO/IEC 17025 accreditation, traceability, and uncertainty documentation. For IATF 16949 certified automotive suppliers, add the requirement for measurement system analysis (MSA) support and the ability to handle the full range of instruments in automotive manufacturing — torque, dimensional, electrical, and pressure.
Key questions for manufacturing: Does the lab cover all my instrument types? Can they handle high-volume calibration campaigns efficiently? Do they offer onsite calibration for fixed production equipment? Do their certificates include everything my IATF auditor will ask for?
Pharmaceutical — FDA GMP and ASEAN GMP
Philippine pharmaceutical manufacturers face the most stringent calibration documentation requirements of any industry. The calibration laboratory must be ISO/IEC 17025 accredited, its certificates must include full measurement data and uncertainty values, and its staff must understand pharmaceutical GMP calibration documentation requirements.
Key questions for pharma: Does the lab have experience calibrating pharmaceutical instruments — stability chambers, autoclaves, HVAC sensors, analytical balances? Can they support temperature mapping and equipment qualification activities? Are their certificates formatted to satisfy FDA Philippines documentation requirements?
Food and Beverage — FDA GMP and HACCP
Food manufacturers need calibration certificates for temperature instruments at CCPs, weighing scales for product weight control, and pH meters. The key is a laboratory that covers these disciplines under ISO/IEC 17025 accreditation and understands HACCP critical control point documentation requirements.
Key questions for food: Does the lab cover temperature and weight calibration — the two most common disciplines for food processing? Can they provide onsite calibration for installed cold storage and processing line instruments? Are their certificates accepted by FDA Philippines GMP inspectors?
Electronics and Semiconductor — PEZA and Export Quality
Philippine electronics and semiconductor manufacturers need electrical calibration for DMMs, LCR meters, oscilloscopes, and power analyzers, combined with temperature calibration for process ovens and chambers. International customer acceptance of certificates is a key requirement.
Key questions for electronics: Does the lab cover the full range of electrical calibration disciplines needed? Are their certificates internationally recognized through ILAC MRA? Can they serve PEZA ecozone facilities with onsite calibration?
Utilities and Power — Revenue Metering and Safety
Power utilities and industrial energy managers need calibration of revenue meters, power analyzers, and high-voltage measurement equipment. Safety is paramount — calibration of protection relay test equipment and insulation resistance testers has direct implications for grid and worker safety.
Healthcare — FDA Philippines and Patient Safety
Hospitals and medical device manufacturers need calibration of autoclaves, laboratory instruments, patient monitoring equipment, and electrical safety analyzers. FDA Philippines requirements for medical device manufacturers apply, and patient safety considerations make accuracy non-negotiable.
Section 8: Why Philippine Businesses Choose PPM Calibration
Based on the criteria covered throughout this guide, Premier Physic Metrologie, Incorporated (PPM Calibration) consistently emerges as the clear choice for Philippine businesses that need calibration services they can stake their compliance on.
25 Years — The Track Record That Speaks for Itself
PPM Calibration has been providing ISO/IEC 17025 accredited calibration services in the Philippines for 25 years. This is not a marketing number — it is a verifiable fact. Twenty-five years of continuous accredited operation means PPM has served clients through multiple generations of ISO standards, through multiple cycles of FDA Philippines regulatory updates, through economic cycles that tested the resilience of Philippine industry.
The clients who have stayed with PPM for years — and the new clients who choose PPM based on their competitors’ or partners’ recommendations — are the most meaningful measure of PPM’s quality and reliability. In an industry where trust is everything, 25 years of sustained client relationships is the most credible credential a calibration laboratory can hold.
ISO/IEC 17025:2017 PAB-DAP Accreditation — Current and Valid
PPM Calibration holds current ISO/IEC 17025:2017 accreditation from the Philippine Accreditation Bureau (PAB-DAP). This accreditation is:
- Granted by the Philippines’ recognized national accreditation body — not self-declared or based on a foreign accreditation body with no Philippine recognition
- Internationally recognized through PAB-DAP’s signatory membership in APLAC and ILAC — accepted in over 100 countries worldwide
- Subject to ongoing surveillance assessment — maintained continuously, not a one-time certification
- Covering the broadest scope of calibration disciplines of any independent calibration laboratory in the Philippines
Full Service Range Under One Accreditation
PPM Calibration’s accredited scope covers temperature, pressure and vacuum, electrical, weight and mass, torque, flow, force, and volume calibration — all major disciplines required by Philippine manufacturing, pharmaceutical, food, electronics, and industrial sectors. This comprehensive scope means clients can consolidate all their calibration needs with a single trusted provider, eliminating the administrative complexity and consistency risks of managing multiple calibration vendors.
Both Laboratory and Onsite Calibration — Both Under Accreditation
PPM Calibration offers laboratory calibration at its environmentally controlled facility and onsite calibration at client facilities throughout Metro Manila, Luzon, and the Philippines. Critically, both service modes are performed under PPM’s ISO/IEC 17025:2017 PAB-DAP accreditation — onsite certificates carry the same technical authority as laboratory certificates. There is no distinction in certificate quality between the two service modes.

Section 9: Frequently Asked Questions — Choosing a Calibration Lab in the Philippines
Q: What is the most important thing to look for when choosing a calibration lab in the Philippines?
A: ISO/IEC 17025:2017 accreditation from PAB-DAP is the single most important credential. Without it, there is no independent verification that the laboratory is technically competent to produce valid calibration results. After confirming accreditation, verify that the scope covers your specific instruments, that certificates include measurement uncertainty, and that the laboratory has experience with your industry’s regulatory requirements.
Q: How do I know if a calibration lab in the Philippines is really accredited?
A: Request the laboratory’s current PAB-DAP ISO/IEC 17025:2017 accreditation certificate and check the certificate number, expiry date, and scope of accreditation. Verify the certificate number against the PAB-DAP online laboratory directory for independent confirmation. Genuine accreditation certificates display the PAB-DAP logo and the ILAC MRA combined mark. ISO 9001 certificates, ‘calibration standard’ claims, and other language are not substitutes.
Q: Can I use a cheaper, unaccredited calibration provider for some of my instruments?
A: For instruments used only for general monitoring where measurement validity is not required for compliance, product release, or safety decisions — possibly. But for any instrument used in quality-critical decisions, product release, ISO audit documentation, FDA GMP compliance, DOLE OSHS assessments, or international customer requirements — no. The risk of an unaccredited certificate failing in an audit or inspection, combined with the potential costs of the resulting non-conformance, almost always outweighs the cost savings.
Q: How many calibration providers should I have?
A: Ideally, one — provided that provider’s accredited scope covers all your instrument types. Using a single accredited provider simplifies vendor qualification, ensures consistent certificate format and quality, reduces administrative burden, and often results in better pricing through volume. PPM Calibration’s broad accredited scope makes it possible for most Philippine businesses to consolidate all their calibration with a single provider.
Q: What should I do if my current calibration certificates are from an unaccredited provider?
A: If you discover that your calibration certificates are not from an ISO/IEC 17025 accredited laboratory, you should take action before your next audit or regulatory inspection. Engage an accredited provider — such as PPM Calibration — to recalibrate your instruments and issue compliant certificates. Update your calibration records to reflect the new accredited certificates. Review whether any compliance-critical measurements were made using instruments calibrated by the unaccredited provider and assess whether a retrospective quality review is needed.
Q: Does PPM Calibration offer a free consultation to help me choose the right service?
A: Yes. PPM Calibration offers free calibration consultation — including advice on which instruments need calibration and at what intervals, guidance on laboratory vs. onsite service selection, and review of your calibration program to identify any gaps or compliance risks. This consultation is available to both existing and prospective clients. Contact PPM Calibration through ppmcalibration.com or via Facebook at facebook.com/ppmcalab to schedule a consultation.
Q: Is it worth paying more for an accredited calibration provider?
A: Yes — consistently and without exception. The additional cost of accredited calibration over unaccredited calibration is typically modest — a few hundred to a few thousand pesos per instrument. Compare this to the cost of a single failed ISO audit major non-conformance (corrective action, recertification review, customer notification, internal investigation — potentially hundreds of thousands of pesos), a single FDA Philippines GMP finding (corrective action requirements, potential production hold, reinspection costs), or a single lost international customer due to non-compliant calibration certificates. The return on the investment in accredited calibration is consistently positive.
Q: How do I get started with PPM Calibration?
A: Getting started with PPM Calibration is straightforward. Visit ppmcalibration.com/request-a-quote and provide your instrument list — including instrument types, quantities, makes and models, and your facility location. PPM will confirm scope coverage, provide a detailed quotation, and schedule your calibration at a time that works for your operations. Alternatively, contact PPM through the website contact page, email, or Facebook at facebook.com/ppmcalab. First-time clients are welcome to request a sample calibration certificate to review before committing.
