scope:
This standard may be used to determine the change in total pressure resulting from airflow in HVAC ducts and fittings.
The test results can be used to determine duct flow losses in pressure loss per unit length. Fitting losses are reported as local loss coefficients.
This standard does not cover interpretation of test data.
PURPOSE
This standard establishes uniform methods of laboratory testing of HVAC ducts and fittings to determine their resistance to airflow.
