This document supplements ISO 17025 by providing specific guidance for both assessors and for laboratories carrying out microbiological testing. It gives detailed guidance on the interpretation of ISO 17025 for those undertaking the examination of materials, products and substances. The guidance is applicable to the performance of all objective measurements, whether routine, non-routine, or as part of research and development. Although it is written primarily for food and environmental microbiological testing, the general principles may be applied to other areas. The guidance given in this document may also be of use to those working towards registration under other quality standards such as GLP, GMP, GCP.
