FAQ

ISO 17025 frequently asked questions

01Who grants ISO 17025 accreditation?

A national accreditation body that is a signatory to the ILAC Mutual Recognition Arrangement. Lisora prepares your laboratory and supports you through the assessment.

02Is ISO 9001 enough for a laboratory?

ISO 9001 covers quality management but not technical competence. ISO 17025 adds requirements for method validation, measurement traceability and uncertainty — which is why customers and regulators ask for it.
