Conformity Assessment

IHE International administers the IHE Conformity Assessment Scheme (CAS), which forms the basis for IHE Conformity Assessment Programs and any official certification of conformance to IHE Profiles associated with such testing programs.

The CAS Scheme consists of two volumes:

  • IHE CAS-1 defines the necessary processes for establishing and managing an IHE Conformity Assessment Program and for accrediting and operating testing labs.
  • IHE CAS-2 defines the standardized test methods for assessing conformity to individual IHE Profiles.

On the basis of the Conformity Assessment Scheme, test laboratories are accredited in accordance with the ISO/IEC 17025 standard, General Requirements for Competence of Calibration and Testing Laboratories. Test reports produced in accordance with this standard are accepted worldwide. IHE International authorizes designated test laboratories accredited under this standard to assess the conformity of products with selected IHE profiles.
