What ASSE International does
ASSE International, founded in 1906 as the American Society of Sanitary Engineering and headquartered in Mokena, Illinois, is an ANSI-accredited standards developer and ANAB- and SCC-accredited third-party product and personnel certification body serving the plumbing and mechanical industries. Its core outputs are 50+ product performance standards (e.g., ASSE 1013 reduced pressure backflow preventers, ASSE 1017 temperature-actuated mixing valves) and 13 professional qualifications standards organized into numbered series (5000 cross-connection control, 6000 medical gas, 12000 infection control, 15000 fire protection, 19000 hydronic, 21000 rainwater catchment, 22000 water treatment). These standards are incorporated into US model plumbing codes (UPC, IPC) and Canadian National Standards, giving them quasi-regulatory force.
The organization operates a five-stream revenue model: product listing fees from manufacturers, personnel certification and recertification fees from individual tradespeople, standards publication sales through the ASSE Webstore and IAPMO Bookstore, membership dues, and annual meeting/event revenue. Customer segments include licensed plumbers and pipefitters, plumbing product manufacturers, code inspectors, healthcare facilities (medical gas, Legionella, infection control), fire protection professionals, water utilities, and HVAC engineers. ASSE is a wholly owned subsidiary of IAPMO R&T and operates a 30-chapter community across the US, Canada, and International regions, with standards developed through ANSI-accredited industry consensus committees.
Distribution combines direct e-commerce (ASSE Webstore, IAPMO Bookstore), searchable online certification directories, approved third-party testing laboratories, and a chapter-based member network. Recent strategic activity has focused on extending the qualifications franchise into adjacent verticals — fuel gas (ASSE 18000 in development), water treatment (Series 22000-2026 launched), and Legionella water safety (ASSE 12080) — and on geographic formalization in Canada (chapter established 2024) and Israel (2020 standards licensing agreement).
