Summary: This standard specifies the determination of the A-weighted sound pressure level of packaging machinery and calculated through the A-weighted sound power level approach. This standard applies to stationary noise generated radiation wideband and narrow band, discrete frequencies and combinations of packaging machinery products. In addition to the repetition rate of less than five per second burst sound, but also applies to non-stationary noise generated packaging machinery products. This standard is especially suitable for field measurements, no need to test the sound source into a dedicated acoustic environment. On the volume of the tested products are no restrictions for oversize product selection that part of the main noise source is measured. According to the method specified in this standard and the measured data can be used: a similar size and type of product for comparison; b assess the product's A-weighted sound power level...
