标准摘要
[中文适用范围]： 本文件规定了： ——滚动轴承润滑脂噪声试验的基本原理、试验装置和试验机； ——测试方法 BQ+、MQ 和 NQ 中使用的符号。 本文件适用于测试滚动轴承润滑脂，特别是未使用的润滑脂。 注：合适的润滑脂是符合 DIN 51818[6] 的 NLGI 1 至 3 级润滑脂。 适用于滚动轴承润滑的润滑脂尤其是符合 ISO 12924 的润滑脂。 根据本文件的测试方法为滚动轴承提供了有意义的结果；然而，它也适用于类似应用中的润滑脂[12][13]。 [外文原描述]： This document specifies: — basic principles, testing assembly and the test machine for noise testing of rolling bearing greases; — symbols used in the test methods BQ+, MQ and NQ. This document is applicable for testing rolling bearing greases, especially of unused grease. NOTE Suitable greases are greases of NLGI classes 1 to 3 according to DIN 51818 [6] . Suitable greases for lubrication of rolling bearings are especially greases according to ISO 12924. The test method according to this document delivers meaningful results for rolling bearings; however, it can also be applied for greases in similar applications [12][13] .
