Accreditation readiness

ISO/IEC 17025 Testing & Calibration Laboratories

Current edition: ISO/IEC 17025:2017

The international standard for the competence, impartiality and consistent operation of testing and calibration laboratories. Accreditation to it means your results are accepted by customers and regulators across borders. We prepare laboratories for that accreditation.

What the standard covers

Requirements, clause by clause

ISO/IEC 17025 combines requirements for impartiality and structure with detailed technical requirements for methods, equipment and results.

4

General requirements

Impartiality and confidentiality.

5

Structural requirements

Legal entity, management, defined scope of activities.

6

Resource requirements

Personnel competence, facilities, equipment, metrological traceability, externally provided products and services.

7

Process requirements

Contract review, method selection and validation, sampling, measurement uncertainty, validity of results, reporting, complaints, nonconforming work, data control.

8

Management system

Option A requirements, or Option B for laboratories with an ISO 9001 system.

Accreditation is assessed for a defined scope of tests or calibrations, together with the accreditation body's own policies, such as those on traceability and proficiency testing.

Why organisations implement it

What accreditation delivers

Accepted results

Reports accepted by customers, regulators and other laboratories internationally.

Tender eligibility

Many contracts and regulations require accredited testing.

Fewer repeat tests

Results accepted across borders reduce duplicate testing.

Technical confidence

Validated methods, known uncertainty and traceable measurements.

Risk-based operation

Risks to impartiality and validity of results managed.

Competitive edge

A clear differentiator for commercial laboratories.

Who decides

Accreditation by your national accreditation body

Testing and calibration laboratories are accredited by national accreditation bodies such as UKAS, DAkkS or PNAC. Accreditation under the Global ACI mutual recognition arrangement is recognised internationally. AEC prepares your organisation for the assessment; the accreditation decision is theirs.

Independent

We prepare you for the accreditation body your customers and regulators recognise.

Assessment-ready

Mock assessment and closed findings before the accreditation visit.

No guarantees

We prepare you thoroughly and never promise an outcome only an accreditation body can decide.

Questions

ISO/IEC 17025 FAQ

Does AEC accredit laboratories?

No. Accreditation is granted by national accreditation bodies such as UKAS, DAkkS or PNAC. AEC prepares your laboratory for that assessment.

Is ISO/IEC 17025 the same as ISO 9001 certification?

No. ISO 9001 certification covers a quality management system. ISO/IEC 17025 accreditation also confirms technical competence to produce valid results for a defined scope of tests or calibrations.

Do we need proficiency testing?

Yes. Laboratories must monitor the validity of results, and accreditation bodies expect participation in proficiency testing or interlaboratory comparisons where available.

Can we accredit only some of our tests?

Yes. Accreditation applies to a defined scope. Many laboratories start with their most requested tests and extend the scope later.
