ASHRAE 70-2006 PDF

The purpose of this standard is to define laboratory methods of testing air outlets and air inlets used to terminate ducted and unducted systems for distribution and return of building air.

This standard was first published in 1972 and revised in 1991. This current edition of the standard updates the 1991 edition by covering a broader range of air-device types and sizes, by specifying commercially available test instruments that have increased accuracy, by defining test facilities and installation procedures to better reflect the device under investigation at its intended application, and by clarifying methods of calculating test data so they apply to the broader range of air devices now available in the market.
