Conformity Assessment in the North American Market: 21st Century Challenges and Opportunities



Belinda L. Collins


Conformity assessemnt arrangements that exist between a variety of national and international bodies and agencies, primarily at the voluntary level, were described in terms of their role in supporting trade facilitation. The role of first party, second party, and third party schemes are described in terms of both value added and cost. NIST's role as a designating authority under the U.S.-EU MRA was discussed, as well as its role in laboratory accreditation. The role of international accreditation bodies such as the International Laboratory Accreditation Cooperation (ILAC) was presented along with the concept of facilitating acceptance of test and callibration data across borders, and thus trade. Finally, the role of the National Cooperation for Laboratory Accreditation (NACLA) in reducing duplicative assessments and increasing confidence in U.S. Laboratory data was discussed.
