本文件规定了滑动轴承用最常见的未填充热塑性聚合物的分类和命名系统。 未填充的热塑性聚合物根据其特殊性能、添加剂的适当水平以及有关其在滑动轴承中应用的信息进行分类。指定系统不包括所有财产；因此，具有相同名称的热塑性聚合物不能在所有情况下互换。 它还概述了最常见的未填充热塑性聚合物的性能和应用，并列出了影响滑动轴承用热塑性聚合物选择的一些基本参数。 注？在进一步的工作过程中，计划编制滑动轴承“热固性聚合物”和“混合聚合物”的标准。

This document specifies a classification and designation system for a selection of the most common unfilled thermoplastic polymers for plain bearings. The unfilled thermoplastic polymers are classified on the basis of appropriate levels of distinctive properties, additives and information about their application for plain bearings. The designation system does not include all properties; thermoplastic polymers having the same designation cannot therefore be interchanged in all cases. It also provides an outline of the properties and applications of the most common unfilled thermoplastic polymers as well as listing some of the fundamental parameters that influence the selection of thermoplastic polymers for use for plain bearings. NOTE？In the further course of the work, it is intended to prepare standards on “thermosetting polymers” and “mixed polymers” for plain bearings.
