description abstractThis standard applies to laboratory and field gas flow measurement for testing heating, ventilating, air-conditioning, and refrigerating systems and components. This standard is restricted to applications where the entire flow stream of gas enters and exits the gas flowmeter in a gas-only state during data recording with the following exceptions:
a. This standard does not apply to airflow measurements at pressures within this range: –25 kPa to +25kPa (–100 in. H2O to +100 in. H2O) referenced to ambient pressure. Those measurements are within the scope of ASHRAE Standard 41.2.
b. This standard does not apply to fan performance rating airflow measurements. Those measurements are within the scope of ASHRAE Standard 51.
c. This standard does not apply to gaseous-phase refrigerant mass flow measurements where the gas flow includes circulating lubricant. Those measurements are within the scope of ASHRAE Standard 41.10.
PURPOSE
This standard prescribes methods for gas flow measurement.
