CASCO is the ISO committee responsible for conformity assessment in ISO. CASCO develops policy and publishes standards related to conformity assessment, but it does not perform conformity assessment activities.


CASCO is made up of a number of groups that take care of different tasks.

CASCO’s standards development work is carried out by working groups of experts who are put forward by the ISO member bodies. The experts do not always belong to the member body but represent an expertise required by the working group.

CASCO’s policy work is support by three standing groups (CPC, TIG, STAR) that work to ensure a consistent and organized approach to conformity assessment.
