Introduction

Laboratories performing testing for conformance to ISO/IEC 19790 and the test requirements in

ISO/IEC 24759 may utilize and require conformance to ISO/IEC 17025:2017. ISO/IEC 17025:2017 gives

generalized requirements for a broad range of testing and calibration laboratories to enable them to

demonstrate that they operate competently and are able to generate valid results.

Laboratories that perform such validations have specific requirements for competence to ISO/IEC 19790

that will enable them to generate valid results.

By providing additional details and supplementary requirements to ISO/IEC 17025:2017 that are specific

to information security testing and evaluation laboratories, this document will facilitate cooperation

and better conformity and harmonization between laboratories and other bodies. This document

may be used by countries and accreditation bodies as a set of requirements for lab assessments and

accreditations.

To help implementers, this document is numbered identically to ISO/IEC 17025:2017. Supplementary

requirements are presented as subclauses additional to ISO/IEC 17025:2017.
