GB/T 7323-2008 in English

《GB/T 7323-2008极压锂基润滑脂》由TC280（全国石油产品和润滑剂标准化技术委员会）归口，TC280SC1（全国石油产品和润滑剂标准化技术委员会石油燃料和润滑剂分会）执行，主管部门为国家标准化管理委员会。
本标准代替ＧＢ７３２３―１９９４《极压锂基润滑脂》。本标准规定了由脂肪酸锂皂稠化矿物润滑油并加入抗氧、极压添加剂所制得的极压锂基润滑脂的分类和标记、要求和试验方法、检验规则及标志、包装、运输和贮存。本标准所属产品适用于工作温度在－２０ ℃～１２０ ℃范围的高负荷机械设备轴承及齿轮的润滑，也可用于集中润滑系统。本标准与ＧＢ７３２３―１９９４相比主要变化如下：
―――由强制性标准修改为推荐性标准；
―――极压锂基润滑脂１号和２号的滴点由１７０ ℃改为１７５ ℃；
―――防腐蚀性结果表述方式由“不大于１级”改为“合格”；
―――增加了第３章分类和标记；
―――增加了第５章检验规则。
