IAPMO Industry Standards
For more than 30 years, IAPMO has developed industry standards (e.g., IGCs, PSs, and TSs) to cover innovative new plumbing products not covered by existing standards. Often, new products or new technologies surge ahead far faster than most standards can keep pace. Through our industry standards, IAPMO provides manufacturers and product developers a vehicle for introducing new products to the marketplace in timely manner.
Although IAPMO industry standards have traditionally focused primarily on plumbing, in the last few years IAPMO has also developed standards for solar heating systems and components, mechanical products (e.g., heating, ventilation, cooling and refrigeration system products), and also for products used in the recreational vehicle and manufactured housing industry.
IAPMO's industry standards are jointly developed by IAPMO staff and stakeholders via an open process, which utilizes the principles of consensus, in accordance with IAPMO Policy S-001 and IAPMO Policy S-008. Such standards are widely accepted by industry and regulators (jurisdictions). Additional information can be found in our Standards brochure.
If you wish to initiate development of a new IAPMO industry standard or revise an existing one, please fill in the Standards Application Form and submit it to standards@IAPMOstandards.org.
