Abstract
Overview
ISO 21250-3:2020 - "Rolling bearings - Noise testing of rolling bearing greases - Part 3: Test and evaluation method MQ" defines the for assessing the noise behaviour of greases used in rolling bearings. The standard specifies the test sequence, measurement principles, calculation methods and the rating scale used to assign a grease noise class. It is intended to be used together with other parts of the series and relevant measurement standards.
