本标准规定了金属基镶嵌型固体自润滑轴承（衬）产品质量等级水平。
产品在符合现行标准的基础上，根据质量水平和使用价值分为合格品、一等品和优等品三个等级。
摩擦系数和PV值的检测规定为：20mm×38mm×48mm的试样在PV1500型摩擦试验机上进行。
速度恒定为13.8 m/min，负荷从零开始，每隔一定时间逐级加载10 kg，以轴承温度超过120℃或摩擦力矩超过40 N·m为破坏标准。
评定产品质量等级时须按各等级所要求的每项指标进行考核。
This standard specifies the product quality grade levels for metal-based embedded solid self-lubricating bearings (bushings).
Based on the current standard, products are classified into three grades: qualified product, first-class product, and superior product, according to quality level and use value.
The test for friction coefficient and PV value is specified as: a specimen of 20mm×38mm×48mm is tested on a PV1500 friction testing machine.
The speed is constant at 13.8 m/min, the load starts from zero and is increased stepwise by 10 kg at regular intervals, with bearing temperature exceeding 120°C or friction torque exceeding 40 N·m as the failure criterion.
When assessing product quality grades, each indicator required for the respective grade must be evaluated.
