GB/T 43617.2-2024 《Rolling bearings—Noise testing of rolling bearing greases—Part 2：Test and evaluation method BQ+》 Related products

The standard GB/T 43617.2-2024 specifies the BQ + test and evaluation method for rolling bearing grease noise testing, which is suitable for evaluating the effect of grease on rolling bearing operating noise. The standard describes in detail the test equipment requirements, test procedures, data collection and processing, and technical specifications for result evaluation to ensure the accuracy and repeatability of the test. The BQ + method provides a scientific basis for the selection of grease suitable for specific applications by quantitatively analyzing the noise performance of grease by simulating actual operating conditions. This standard is widely applicable to quality control and Product Research & Development in bearing manufacturing, Machinery and related industries.
