Standards Committee
 American National Standards (ANSI) 
IAPMO Standards > American National Standards

For more than 30 years, IAPMO has developed American National Standards (ANS), initially as the Secretariat for the ANSI Z124 Technical Committee, and since 2005 as an ANSI-accredited standards development organization, thus changing the designation of the standards to IAPMO/ANSI.

Although IAPMO's standards have traditionally focused primarily on plumbing, in the last few years IAPMO has also developed national standards for solar heating systems and components.

IAPMO's national standards are developed via an open consensus process, in accordance with the ANSI Essential Requirements: Due process requirements for American National Standards and the IAPMO PP-1 Policies and Procedures for Consensus Development of American National Standards, and approved by the respective standards committee.
