ASSE: American Society of Sanitary Engineering

ASSE, the American Society of Sanitary Engineering, is a nonprofit organization that develops and publishes standards aimed at preventing unsanitary design in plumbing systems. Headquartered in Westlake, United States, ASSE standards contribute heavily to the IAPMO Uniform Plumbing Code, the overarching standard for plumbing in the United States. With 70 member companies and many more individual members, ASSE work promotes the prevention rather than cure philosophy. Standards from ASSE 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.

Below are ASSE's best-selling standards. To find additional standards, please use the search bar above.

ANSI/ASSE 1010-2004

Performance Requirements for Water Hammer Arresters

This standard applies to devices classified as water hammer arresters having a permanently sealed cushion of water or gas isolated from the water way and designed to provide continuous protection, without maintenance, against detrimental surge pressures within the water distribution system. Water hammer arresters are installed on water distribution system piping to prevent over pressures within water distribution systems, thereby prolonging the service life of valves, piping, fittings, trim, equipment, appliances, appurtenances and other devices which are part of the distribution system and to eliminate noise.

ASSE 1016-2017/ASME A112.1016-2017/CSA B125.16-17

Performance requirements for automatic compensating valves for individual showers and tub/shower combinations

This is the second edition of the tr-harmonized ASSE 1016/ASME A112.1016/CSA B125.16, Performance Requirements for Automatic Compensating Valves for Individual Showers and Tub/Shower Combinations. It supersedes the previous edition published in 2011.This standard applies to automatic compensating valves intended to be installed at the point of use, where the user has access to flow or final temperature controls, and where no further mixing occurs downstream of the device.This standard covers automatic compensating valves intended to control the water temperature to wall or ceiling mounted: a) hand-held showers; b) shower heads; c) body sprays either in individual shower or tub/shower combination fittings; and d) tub spouts when part of tub/shower combination fittings. 


ASSE Standard 1004-2017

Performance Requirements for Backflow Prevention Requirements for Commercial Dishwashing Machines

Applies to backflow prevention devices used on potable water supplies connected to commercial dishwashing machines. The backflow prevention devices used in these applications include atmospheric type vacuum breakers complying with ASSE 1001, hose connection vacuum breakers complying with ASSE 1011, pressure vacuum breakers complying with ASSE 1020, hose connection backflow preventers complying with ASSE 1052, spill-resistant vacuum breakers complying with ASSE 1056, and air gaps.


ASSE Standard 1024-2017

Performance Requirements for Dual Check Backflow Preventers

This standard applies to devices classified as dual check backflow preventers. The purpose of this device is to keep polluted water from flowing back into the potable water system when pressure is temporarily higher in the polluted part of the system than in the potable water piping. The devices covered by this standard are intended to protect the potable water supply from low hazard pollution at residential service lines and individual outlets. Dual check backflow preventers consists of two (2) independently acting check valves, internally force loaded to a normally closed position, designed and constructed to operate under intermittent or continuous pressure conditions with cold water service. Usage with hot water is limited to the temperature specified by the manufacturer. 


ASSE Standard 1082-2018

Performance Requirements for Water Heaters with Integral Temperature Control Devices for Hot Water Distribution Systems

This standard covers water heaters with defined setpoint controls under various steady state flow conditions. ASSE 1082 is for water heaters that control the outlet temperature to specific limits and are installed within a hot water distribution system but not at point-of-use. The water heater shall consist of a heat exchanger, a cold water inlet connection, a hot water outlet connection, and a means for precisely governing the outlet temperature. The water heater controller shall be listed to the appropriate electrical safety standard in accordance with the water heater category. These devices are not intended for end use applications without point-of-use control valves, as specified by ASSE 1016 / ASME A112.1016 / CSA B125.16, ASSE 1069, ASSE 1070 / ASME A112.1070 / CSA B125.70, or other appropriate standards. 


ANSI/ASSE 1017-2009

Performance Requirements for Temperature Actuated Mixing Valves for Hot Water Distribution Systems

These devices are used for controlling in-line water temperatures in domestic potable hot water systems and shall be installed at the hot water source. They are not intended for end use application. They shall consist of a hot water and a cold water inlet connection and a mixed water outlet connection plus a temperature sensing and controlling element and a means for adjusting the outlet water temperature.


ASSE 1022-2021

Performance Requirements for Backflow Preventer for Beverage Dispensing Equipment
