ISO 1043-1:2011定义了塑料中使用的基本聚合物的缩写术语、这些术语的组件符号以及塑料特殊特性的符号。它只包括已被确定使用的缩略语，其目的是防止给定塑料出现多个缩略语，并防止给定缩略语被以多种方式解释。 附录中给出了新缩略语的编制指南、用于形成塑料缩略语的塑料术语组件的符号参考列表，以及按类型分组的聚合物缩略语分类。

ISO 1043-1:2011 defines abbreviated terms for the basic polymers used in plastics, symbols for components of these terms, and symbols for special characteristics of plastics. It includes only those abbreviated terms that have come into established use and its aim is both to prevent the occurrence of more than one abbreviated term for a given plastic and to prevent a given abbreviated term being interpreted in more than one way. Guidance for the preparation of new abbreviated terms, reference lists of symbols for the components of plastics terms used to form the abbreviated terms for plastics, and a classification of abbreviated terms for polymers grouped by type are given in annexes.
