ISO 17021 (Standard for Conformity Assessment Bodies)
What is ISO 17021?
SO/IEC 17021-1:2015 contains principles and requirements for the competence, consistency and impartiality of bodies providing audit and certification of all types of management systems.
Certification bodies operating to ISO/IEC 17021-1:2015 do not need to offer all types of management system certification.
Certification of management systems is a third-party conformity assessment activity and bodies performing this activity are therefore third-party conformity assessment bodies.
