Since 1938, the National Association of Architectural Metal Manufacturers (NAAMM) has represented a wide variety of architectural metal products for building construction. NAAMM currently has six operating divisions, which promote the use of their specific products through the development and distribution of technical standards.

MSS, the Manufacturers Standardization Society of the Valve and Fittings Industry is a non-profit standards developing organization that is devoted to the development of the industry. Standards written by MSS address valves, valve actuators, valve modification, pipe fittings, pipe hangers, pipe supports, flanges, and associated seals. These materials and associated guidelines are used in almost every industry, and are found in facilities for waste management, nuclear energy, and oil refining.Standards from MSS are available both individually, directly through the ANSI webstore, and as part of a Standards Subscription. If you or your organization are interested in easy, managed, online access to standards that can be shared, a Standards Subscription may be what you need - please contact us at: StandardsSubscriptions@ansi.org or 1-212-642-4980 or Request Proposal Price.

The divisions are:

Through NAAMM, the six divisions receive symbiotic benefits. For example, the Metal Finishes Manual provides information on finishing which is applicable to all Divisions. Issues related to topics of mutual interest to manufacturers, such as workman's compensation, employee relationships, right-to-know, insurance issues, EPA and OSHA are addressed among NAAMM members.
