About ASSE's Standards Program

ASSE’s product performance standards, developed through industry consensus, detail how a product is intended to function under normal operating conditions and include testing procedures and requirements for performance, health and safety. Standards may also include requirements for construction, maintenance and operation.

ASSE’s professional qualifications standards, also developed through industry consensus, set minimum education and performance requirements for professionals who test, install, inspect and maintain our buildings’ water and sanitation systems.

ASSE standards are developed under the ANSI-accredited standards development process.

ASSE Product and
PQ standards

Deep knowledge and constant improvement of nearly 50 product performance standards for plumbing components, most notably backflow prevention devices and temperature actuated mixing valves, as well as eight professional qualifications standards puts ASSE in a class of its own.

Standards development process

Product and Professional Qualifications Standards Committees were established on ANSI's policy of openess and consensus with specific responsibilities, as shown in ASSE International's Bylaws. The interests of the public and the producers are the most vital parts of the procedures, with emphasis on performance and application needs.
