Conformance Assessment Applications for Recognition of Plumbing Product Approvals



L S. Galowin, Maureen A. Breitenberg


Harmonization of regulatory requirements through application of conformity assurance procedures in regulated product acceptance is discussed. Conformity assessment procedures include inspection and testing, product certification, quality system registration, and laboratory accreditation. Manufactured plumbing products are usually regulated by legal requirements through adoption of plumbing codes and reference to national plumbing standards for assuring performance for health, safety and code provisions for installed building systems. Introduction of legal requirements from conformity procedures was established for regulatory requirements applied to plumbing product approvals in the state of Oregon, United States. Reference to international guides for conformity applications to recognized plumbing standards and code organization requirements could be useful as a model under international mutual recognition arrangements for regulatory sectors that would contribute to elimination of trade barriers. The Oregon regulation demonstrates that combining conformity assessment methods is feasible and practical when applied to regulatory actions. That model eliminates selective control for approved plumbing product listing(s) with costly duplicative testing and provides for expanding commercial product applications. Legislative mandates for legally required applications must apply to implement regulatory sector applications.
