If you need the legal, enforceable version of the standard for compliance, you must avoid free PDF traps. Here is the legitimate path.
Unlike general safety codes (like ASME Boiler and Pressure Vessel Code), ASHRAE 70 provides a uniform, reproducible laboratory method for testing the relieving capacity of pressure relief valves (PRVs). These valves are the last line of defense in a refrigeration system; if the pressure vessel overheats or malfunctions, the PRV must open and vent enough refrigerant to prevent a catastrophic explosion.
Standard 70 dictates:
If you are looking for the most current version because the 2006 edition is outdated, here is the version history:
Key Updates since 2006: The newer versions typically include more refined requirements for testing accuracy, updated definitions, and occasionally new annexes regarding how to handle specific types of high-induction diffusers or noise calculation methods.
ASHRAE Standard 70-2006 provides guidelines for the testing and evaluation of the thermal performance of buildings, specifically focusing on the thermal envelope and energy efficiency. This standard was published by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE).
