- Scope
- This standard specifies a method for determining noise sound power levels using sound intensity measurements on site, with engineering-level accuracy. This standard is applicable to the on-site noise and sound power level measurement of various types of general machinery such as compressors with prime movers, refrigeration machines, separation machinery, reciprocating pumps, HVAC, etc., especially for large units that do not meet the requirements of general sound power level measurement methods. Applicable to environmental conditions.
