Accreditation For Metrology

Accreditation of Metrology helps to deliver accepted definitions and standards for measurements

Most sophisticated products require testing for compliance with specifications and safety regulations before release into markets. Test documentation is very often the basis of trade.

The accuracy of measurements is something that everyone relies on. From the amount of petrol delivered at the pump to the amount of medication patients are given, whether it is ensuring a bridge fits its allotted span other is a reliance on the national measurement system which is underpinned by ISO calibration

ISO 17025 is the internationally recognized standard used to accredit calibration laboratories to provide confidence in the comparability and accuracy of measurements. In this we can include temperature and humidity, pressure, vacuum and flow, magnetics, acoustics, density, dimensional, force, hardness, mass and volume.

Accreditation in Metrology is the formal recognition by an authoritative body that a laboratory or organization is competent to perform specific types of measurement, calibration, and testing according to internationally recognized standards.

It’s the backbone of trust and reliability in measurement science, ensuring that measurements are accurate, traceable, and comparable worldwide.

Core Purpose: Why is Accreditation Crucial?

1. Establishing Trust and Confidence: An accredited certificate or report is accepted globally by regulators, customers, and trading partners. It answers the question: “Can I trust this measurement?”
2. Ensuring Traceability: Accredited labs must ensure their measurements are traceable to the International System of Units (SI) through an unbroken chain of calibrations to national or international measurement standards (e.g., NIST in the USA, NPL in the UK, PTB in Germany).
3. Facilitating Global Trade: It removes technical barriers to trade. A product tested or calibrated in one country is accepted in another without re-testing (“tested once, accepted everywhere”).
4. Supporting Regulatory Compliance: Many industries (pharmaceuticals, environmental, medical devices) require accredited metrology for legal compliance.
5. Risk Management: Reduces the risk of incorrect measurements leading to product failure, safety issues, or financial loss.

Key Standards for Metrology Accreditation

The primary international standard is:

• ISO/IEC 17025:2017 – “General requirements for the competence of testing and calibration laboratories”
  This is the gold standard for metrology labs. It covers all aspects of laboratory operations critical to producing valid, reliable data:
  • Impartiality and structural integrity
  • Competence of personnel
  • Adequacy of methods (validated/standard methods)
  • Calibration and maintenance of equipment
  • Measurement traceability
  • Quality assurance of results
  • Reporting of results

Other relevant standards include:

• ISO 17034:2016: For reference material producers (RMPs).
• ISO 15189:2022: For medical laboratories (applying metrology principles in a medical context).
• ISO/IEC 17020:2012: For inspection bodies (which often involve measurement activities).
• ISO 9001:2015: While a quality management system standard, it often works in tandem with ISO/IEC 17025, but 17025 is far more technically specific for labs.

---

The Accreditation Bodies

Accreditation is granted by national or regional accreditation bodies, which are themselves evaluated through peer review in international forums.

• National Examples:
  • USA: ANSI-ASQ National Accreditation Board (ANAB), A2LA (American Association for Laboratory Accreditation)
  • UK: UKAS (United Kingdom Accreditation Service)
  • Germany: DAkkS (Deutsche Akkreditierungsstelle)
  • China: CNAS (China National Accreditation Service)
• International Recognition: These bodies are often signatories to the ILAC (International Laboratory Accreditation Cooperation) MRA (Mutual Recognition Arrangement). An accreditation certificate with the ILAC MRA mark is recognized in over 100 economies, facilitating global acceptance.

---

Process of Obtaining Accreditation

1. Preparation: The laboratory implements a management system and technical processes that comply with ISO/IEC 17025.
2. Application: Apply to a chosen accreditation body, submitting a quality manual and other documentation.
3. Document Review: The accreditation body reviews the lab’s management system documents.
4. On-Site Assessment: A team of expert assessors (technical experts in the lab’s field) visits the lab to:
   • Audit processes and records.
   • Interview personnel.
   • Witness demonstrations of calibrations/tests (proficiency testing).
   • Review measurement uncertainty calculations and traceability.
5. Corrective Actions: The lab addresses any non-conformities found during the assessment.
6. Granting Accreditation: If all requirements are met, the accreditation body grants accreditation for a specific scope (a detailed list of measurements/calibrations the lab is approved for).
7. Surveillance and Reassessment: Regular surveillance visits (often yearly) and full reassessments (every 4-5 years) ensure ongoing compliance.

---

Key Technical Concepts in Metrology Accreditation

• Scope of Accreditation: A precise list of the measurements, calibrations, or tests a lab is accredited to perform. This is the lab’s “certificate of competence.”
• Measurement Uncertainty (MU): A quantitative indicator of the quality of a measurement. Accredited labs must evaluate and report MU for their results. It is a fundamental requirement of ISO/IEC 17025.
• Proficiency Testing (PT)/Interlaboratory Comparisons: Accredited labs must regularly participate in PT schemes to validate their technical competence against other labs.
• Reference Standards and Equipment: All critical equipment must be calibrated, and standards must be traceable to national or international standards.

---

Who Needs It?

• Calibration Laboratories: Servicing industry by calibrating instruments (micrometers, oscilloscopes, pressure gauges, etc.).
• Testing Laboratories: Performing material testing, environmental analysis, etc.
• In-house Metrology Labs: Within large manufacturing companies (e.g., aerospace, automotive) to ensure their production measurements are valid.
• National Metrology Institutes (NMIs): Like NIST, which are accredited by peer NMIs through the CIPM MRA (a higher-level framework for national standards).
• Legal Metrology Services: For verification of instruments used in trade (scales, fuel pumps, gas meters).

Conclusion

In essence, accreditation is the formal proof of a metrology laboratory’s competence. It transforms a measurement from a simple number into a credible, defensible, and internationally accepted piece of data. It is the critical infrastructure that supports innovation, quality, safety, and fair trade in the global economy.

What is Required Accreditation For Metrology

Here’s a breakdown of the accreditation requirements based on different roles and goals.

---

1. For a Commercial Calibration or Testing Laboratory

If you sell measurement, calibration, or testing services to external customers, accreditation to ISO/IEC 17025 is effectively mandatory to be competitive and credible.

• Primary Requirement: ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories).
• Why it’s Required: It’s the international benchmark. Customers (especially in regulated industries), tenders, and contracts will demand it. Without it, your reports lack global recognition.
• Optional but Valuable: Accreditation to ISO 17034 if you produce Reference Materials.

2. For an In-House/Corporate Metrology Laboratory

If you perform measurements and calibrations to support your own company’s quality control, manufacturing, or R&D, the requirement is often driven by internal quality systems and customer contracts.

• Typical Requirement: ISO/IEC 17025 is strongly preferred and often contractually mandated by customers (e.g., in automotive, aerospace, medical device sectors).
• Alternative/Stepping Stone: Many labs start with implementing ISO 9001 (Quality Management System), which requires controlled calibration but is less technically rigorous than 17025. However, major customers often require 17025 for measurement data used in product validation.
• Key Driver: Customer requirements in supply chains (e.g., ISO/TS 16949 for automotive, AS9100 for aerospace) frequently stipulate that measurement equipment must be calibrated by labs competent to ISO/IEC 17025.

3. For Legal Metrology (Government-Regulated Measurements)

This covers measurements that impact public safety, health, fair trade, and the environment (e.g., fuel pumps, water meters, breathalyzers, scales in supermarkets).

• Primary Requirement: Compliance with national legal metrology regulations (e.g., OIML recommendations, NIST Handbook 44 in the USA, Measuring Instruments Directive in the EU).
• Accreditation’s Role: The organizations that verify, inspect, and certify these measuring instruments are often required to be accredited to ISO/IEC 17020 (for inspection bodies) or ISO/IEC 17065 (for product certification bodies). The calibrations supporting this work are done by labs accredited to ISO/IEC 17025.

4. For a National Metrology Institute (NMI)

NMIs (like NIST, NPL, PTB) maintain national measurement standards and provide the highest level of traceability.

• Primary Requirement: Participation in the CIPM MRA (Mutual Recognition Arrangement). This is not a traditional “accreditation” but a peer-review system among NMIs.
• How it Works: NMIs compare their measurement standards through international comparisons. Their Calibration and Measurement Capabilities (CMCs) are reviewed and published in the BIPM KCDB. This is the highest-level “accreditation” for national measurement standards.
• Supporting Role: Their calibration services are often accredited to ISO/IEC 17025 as well, to serve industry needs.

5. For Individuals (Metrologists and Calibration Technicians)

While accreditation applies to organizations, individual competence is a core part of it.

• Primary Requirement: There is no single mandatory global certification for individuals.
• Common Standards: Organizations often require personnel to meet the competence guidelines outlined in:
  • ISO/IEC 17025 (clauses 6.2.1 – 6.2.5) which mandates demonstrated competence.
  • ANSI/NCSL Z540.3 (U.S. standard for calibration labs).
• Voluntary Certifications: To demonstrate competence, individuals pursue certifications like:
  • CMI (Certified Measurement & Verification Professional) from AEE.
  • CCM (Certified Calibration Technician) through ASQ or other bodies.
  • Metrology-specific certifications from NIST, NPL, or other training institutions.

---

Industry-Specific Mandates

• Medical Devices & Pharmaceuticals (FDA/ISO 13485): Requires equipment calibration critical to product quality. Using an ISO/IEC 17025 accredited lab is the clearest, most defensible way to meet FDA/EU MDR expectations for measurement data in submissions and audits.
• Aerospace (AS9100/NADCAP): NADCAP for measurement and testing explicitly requires accreditation to ISO/IEC 17025 for calibration suppliers.
• Automotive (IATF 16949): Mandates that calibration sources must demonstrate competence, with ISO/IEC 17025 being the recognized standard.
• Environmental Testing (EPA Regulations): Requires labs to be accredited (often to ISO/IEC 17025) for data submitted for regulatory compliance.

Summary: The Bottom Line

• For Organizations Providing Measurement Services: ISO/IEC 17025 accreditation is the universal, non-negotiable requirement for technical credibility and market access. It is enforced by customer contracts, industry standards, and regulators.
• For Organizations Using Measurements: You are required to use accredited calibration services (ISO/IEC 17025) if your customers or quality management system (like AS9100, IATF 16949) demand it. It is the best practice to mitigate risk.
• For Individuals: Competence must be demonstrated per ISO/IEC 17025, often supported by voluntary personal certifications.

In essence, if your measurements need to be trusted beyond your own walls—for trade, regulation, litigation, or complex supply chains—accreditation to ISO/IEC 17025 is not optional; it is required.

Key Takeaway Triggers:

You need metrology accreditation WHEN:

1. Legally Mandated: Public safety, trade, or specific regulations require it
2. Contractually Required: Customer contracts specify accredited data
3. Regulatorily Expected: Industry norms or standards demand it
4. Commercially Necessary: Market access depends on credible data
5. Legally Defensible: Data may face legal challenge

Most Critical Timing: Accreditation must be in place BEFORE data is used for regulatory decisions, commercial claims, or legal proceedings—not as an afterthought.

The trend is clear: as measurement complexity increases and global harmonization progresses, the “when” of accreditation requirements is shifting earlier in development cycles and becoming more pervasive across industries.

✅ All points where measurement data crosses organizational boundaries
✅ All facilities generating data for regulatory submissions
✅ All commercial calibration/testing service providers
✅ All legal metrology verification points
✅ All critical supply chain measurement nodes
✅ All international trade compliance testing locations

The trend is toward global harmonization—what starts as a regional requirement (EU MDR) often becomes a global expectation. The safest approach is to assume accreditation is required whenever measurements support product quality, safety, regulatory compliance, or commercial transactions. When in doubt, implement ISO/IEC 17025—it’s increasingly becoming the universal passport for credible measurement data worldwide.
