滚动轴承 滚动轴承润滑脂噪声测试 第4部分：测试和评估方法NQ
Application Summary AI generated
This standard specifies the NQ test and evaluation method for measuring the noise generated by greases used in rolling bearings. It is applied in the bearing manufacturing and lubrication industries to assess the acoustic performance of greases under controlled laboratory conditions. The method helps ensure that greases meet noise-level requirements for applications such as precision machinery, electric motors, and automotive components.
