ASHRAE 158.2-2006 Standard 158.2-2006 -- Methods of Testing Capacity of Refrigerant Pressure Regulators (ANSI Approved)
standard by ASHRAE, 2006
This standard provides methods of determining the mass flow capacity of refrigerant pressure regulators with sufficient accuracy to facilitate proper engineering application of the device in systems operating at various conditions with various refrigerants by
a. prescribing a method of measuring key flow and gradient characteristics of refrigerant pressure regulators using air or water as the working fluid and
b. prescribing computational means to enable reliable prediction of refrigerant vapor and liquid mass flow capacity based on the measured flow and gradient characteristics.
