ISO/IEC 17025 Laboratory Audit Checklist

A working kit for internal audits of a testing or calibration laboratory against ISO/IEC 17025:2017. The checklist follows the standard from clause 4 to clause 8, so each finding can be traced to a requirement, and the log gives you the equipment and calibration records that auditors and assessors ask for first.

What is inside

ISO/IEC 17025 Laboratory Audit Checklist — 114 checks in 11 sections across clauses 4 to 8: impartiality and confidentiality, structure, resources, the laboratory process from contract review to the report, and the management system. Each check is a statement you can find evidence for, with Yes / No / N/A boxes and space for notes.

Equipment and Calibration Log — four templates: an equipment register, a calibration and intermediate check schedule, a calibration record and an out-of-tolerance / nonconforming work record.

Both documents as a designed, print-ready PDF and as an editable Word file.

Who it is for

Laboratory managers, quality managers, technical managers and internal auditors in testing and calibration laboratories — whether you are preparing for an accreditation assessment, keeping an accredited laboratory in shape, or running an in-house laboratory that wants results people can rely on.

How to use it

Audit the technical work as well as the paperwork. Pick a few recent reports or certificates and trace each one backwards: the contract review, the method and its verification or validation, the person and their authorisation, the equipment and its calibration, the environmental conditions, the raw data, the uncertainty, the quality control results and the review of the report. Witness a test or calibration being done. Use the checklist to make sure nothing is missed. For every No, write a nonconformity that states the requirement, the evidence and why it does not conform.

This kit covers the standard only. Accreditation bodies and regulators publish their own requirements and policies, for example on proficiency testing, metrological traceability and the use of accreditation symbols — check the ones that apply to your laboratory, and check which edition of the standard applies to you.
