CASCO is the ISO committee that works on issues relating to conformity assessment.
CASCO develops policy and publishes international standards related to conformity assessment, it does not perform conformity assessment activities.
As ISO standards for CA and accreditation are used widely at the international level, they facilitate mutual recognition of CA results
Membership to CASCO is open to ISO full and correspondent members

ISO has developed a series of standards for the operation of each of the CABs and for the operation of ABs, as well as for peer evaluation and other associated activities.
These standards are referred to as the ISO/CASCO Toolbox and have been developed by the ISO Committee on conformity assessment (ISO/CASCO). It is the only committee developing standards that is based in Geneva and managed directly by ISO.
