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).

To get the most updated information or to access the standard, you can follow these steps:

Given that standards can change and that direct links or specific instructions might not always be up-to-date, it's best to follow the general steps above to find the most current version of ASHRAE Standard 70 or any other standard you're interested in.

Officially titled "Method of Testing the Performance of Air Outlets and Inlets," ASHRAE Standard 70-2006 serves a vital role in the HVAC industry.

Before this standard, testing airflow performance could vary significantly between manufacturers, making it difficult for engineers to compare products "apples-to-apples." Standard 70 establishes a uniform method for testing, rating, and reporting the performance of:

Essentially, if you are selecting a diffuser for a conference room and need to know its throw, drop, and sound power level, the data you are looking at was likely generated using the protocols set in Standard 70.

If you specifically need 70-2006 for legacy research, ASHRAE does not freely distribute outdated standards. However, they offer the ASHRAE Standards CD Colleciton (Historical), which includes every version back to 2000. Alternatively, university engineering libraries often have physical or digital archival access.

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:
