本文件建立了一个扩展的分类，包括环境可接受润滑剂的子类别，并根据ISO 6743-6规定了CKH、CKJ和CKM类矿物或合成基润滑剂的最低要求，以及用于润滑开式和半封闭齿轮的环境可接受润滑剂的子类别。 本文件涵盖了行业中目前最常见的开式和半封闭式齿轮系统中使用的润滑剂。它不包括与温度和极端充电条件有关的极端使用情况。 注1:对于在特殊情况下使用，润滑油供应商和采购商可就产品的附加测试方法和可接受性标准达成一致。 注2:本文件可结合ISO 6743-6阅读。

This document establishes an extended classification which includes sub-categories of environmentally acceptable lubricants and specifies the minimum requirements for mineral or synthetic based lubricants for the categories CKH, CKJ and CKM, according to ISO 6743-6, and their sub-categories of environmentally acceptable lubricants, intended for the lubrication of open and semi-enclosed gears. This document covers the lubricants applied in the open and semi-enclosed gear systems most currently encountered in the industry. It does not cover the extreme cases of use with regards to temperature and extreme charges conditions. NOTE 1 For use in exceptional conditions, suppliers and purchasers of lubricants can mutually agree on additional testing methods and acceptability criteria of the products. NOTE 2 This document can be read in conjunction with ISO 6743-6.
