Summary:
This standard specifies the following contents related to machines and equipment: - Indication of noise emission values; - The noise emission values of the product and acoustic information related to the product should be provided in the technical documents; - The verification method of the noise emission values is explained. The noise emission indication values used in this standard can be divided into single-value noise emission indication values Ld or dual-value noise emission indication values L and K. L is the directly measured noise emission value, K is the uncertainty associated with the measurement, Ld is the sum of L and K, the upper limit value that cannot be exceeded within the confidence range obtained by repeated measurements, and Ld corresponds to the Lc label value defined in GB/T14573.1.
