ASHRAE 158.1-2024

ANSI/ASHRAE Standard 158.1 provides a standard method of test for the capacity of refrigerant solenoid valves. ANSI/AHRI Standard 760 (I-P), Performance Rating of Solenoid Valves for Use With Volatile Refrigerants, and ANSI/AHRI Standard 761 (SI), Performance Rating of Solenoid Valves for Use With Volatile Refrigerants, require this standard be used as a method of test for capacity. It is further anticipated that AHRI will continue to maintain Standard 760/761 as it relates to standard methods of rating refrigerant service solenoid valves. AHRI Standard 760/761 may also include information concerning other solenoid valve performance characteristics.

ANSI/ASHRAE Standard 15, Safety Standard for Refrigeration Systems, and ANSI/ASHRAE Standard 34, Designation and Safety Classification of Refrigerants, list the various refrigerants to which this standard is applicable.

The 2024 edition of Standard 158.1 includes updated references.
