  Description:

Acoustics - Noise test code for compressors and vacuum pumps - Engineering method (Grade 2) (ISO 2151:2004)

  Purpose

This International Standard specifies methods for the measurement, determination and declaration of the noise emission from portable and stationary compressors and vacuum pumps. It prescribes the mounting, loading and working conditions under which measurements are to be made, and includes measurement or determination of the noise emission expressed as - the sound power level under specified load conditions, - the emission sound pressure level at the work station under specified load conditions. It is applicable to - compressors for various types of gases, - oil-lubricated air compressors, - oil-flooded air compressors, - water injected air compressors, - oil-free air compressors, - compressors for handling hazardous gases (gas compressors), - compressors for handling oxygen, - compressors for handling acetylene, - high-pressure compressors [over 4 Mpa (40 bar)], - compressors for application at low inlet temperatures, i.e. below 0 °C, - large compressors (over 1 000 kW input power), - portable and skid-mounted air compressors, and - rotary positive displacement blowers and centrifugal blowers and exhausters in applications u 0,2 MPa (u 2 bar).
