(m)  ASSE Standard 1012-2021, "Performance Requirements for Backflow Preventers with an Intermediate Atmospheric Vent" (ANSI Approved: November 2021).  This standard sets forth regulations and requirements for devices that have functional capabilities for preventing both back-siphonage and back pressure and which can operate under continuous or intermittent pressure conditions.

(n)  ASSE Standard 1013-2021, "Performance Requirements for Reduced Pressure Principle Backflow Prevention Assemblies" (ANSI Approved: June 2021). This standard sets forth regulations and requirements for reduced pressure principle backflow prevention assemblies.  These devices are designed to operate under continuous pressure conditions.

(o)  ASSE Standard 1015-2021, "Performance Requirements for Double Check Backflow Prevention Assemblies" (ANSI Approved: June 2021).  This standard sets forth regulations and requirements for double check backflow prevention assemblies.  These assemblies are designed and constructed to operate under intermittent or continuous pressure conditions.

(p)  ASSE Standard 1020-2020, "Performance Requirements for Pressure Vacuum Breaker Assemblies" (ANSI Approved: February 2020).  This standard sets forth regulations and requirements for vacuum breaker assemblies.  These devices are intended for use in both high and low hazard applications.

(q)  ASSE Standard 1024-2017(R2021), "Performance Requirements for Dual Check Backflow Preventers" (ANSI Approved: June 2021).  This standard sets forth regulations and requirements for dual check backflow preventers.  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.

(r)  ASSE Standard 1047-2021, "Performance Requirements for Reduced Pressure Detector Backflow Prevention Assemblies" (ANSI Approved: June 2021).  This standard sets forth regulations and requirements for reduced pressure detector backflow prevention assemblies.  These devices are designed to detect low rates of flow up to 2.0 gpm (0.13 L/s) caused by leakage or unauthorized use.

(s)  ASSE Standard 1048-2021, "Performance Requirements for Double Check Detector Backflow Prevention Assemblies" (ANSI Approved: June 2021).  This standard sets forth regulations and requirements for double check detector backflow prevention assemblies.  These assemblies are also designed to detect low rates of flow up to 2 gpm (0.13 L/s) caused by leakage or unauthorized use.

(t)  ASSE Standard 1052-2016 "Performance Requirements for Hose Connection Backflow Preventers" (ANSI Approved: June 2016).  This standard sets forth regulations and requirements for hose connection backflow preventers.  These devices are designed to be installed on the discharge side of a hose threaded outlet on a potable water system.  These two-check devices protect against backflow, due to back siphonage or low-head backpressure, and are field testable to certify protection under the high-hazard conditions present at a hose threaded outlet.
