ISO Guide 25 Replaced by ISO 17025

ISO 17025, “General Requirements for the Competence of Testing and
Calibration Laboratories,” has been approved as a replacement for ISO
Guide 25.

The American Association for Laboratory Accreditation (A2LA) plans to
begin assessing to ISO 17025 this July. After a phase-in period of two
years, ISO Guide 25 will be withdrawn.

The new document defines requirements to be met for laboratories to be
recognized as competent to carry out tests and calibrations. Six new
requirements are included, along with a number of significant changes
to previous ISO Guide 25 requirements.
