This document specifies the technical specification, measuring methods and inspection rules for the noise of deep groove ball bearing (hereinafter referred to as bearings) with boundary dimensions conforming to 0, 2 and 3 diameter series in GB/T 276-1994, nominal inside diameter of 3~120mm and radial internal clearance conforming to Groups 0, 2 and 3 of internal clearance in GB/T 4604-2006.
This document specifies the measurement method for the determination of sound level by measuring bearing surface vibration and this method is applicable to situations with high background noise. Bearing noise pressure level in production site may also be measured according to octave frequency specified in Table 1.
This document is applicable to the measurement of bearing noise sound level by test instrument and adopted acceleration sensor conforming to the principle specified in GB/T 16539-1996.
This document is applicable to the inspection of bearing by manufacturing plant and user acceptance.
