1.1本术语的目的是提供塑料相关术语的统一缩写。缩写术语在广泛使用中不断发展。编制本汇编是为了避免给定塑料术语出现一个以上的缩略语，以及缩略语的多个含义。 1.2这些缩略语的范围包括与成分有关的塑料术语，以及根据制备模式或原理区别特征与类型或种类有关的塑料术语。 还包括与塑料共聚物、共混物和合金以及增塑剂、填料等添加剂有关的术语的缩写。 注1 — 实践中给出了与橡胶成分有关的代码 D1418 . 1.3本文未试图将聚合物的速记术语正式系统化。国际纯化学和应用化学联合会正在研究和标准化自然和合成聚合物领域科学文献中使用的术语，包括命名法、代码、符号和配方名称。 2. 1.4这些缩写术语绝不包括塑料术语。一般来说，它们代表那些已被广泛使用的术语。由于人们认识到，除非缩写词被普遍接受和使用，否则没有任何有用的用途，因此没有人试图建立一个严格的代码来设计标准缩写词。这将导致尴尬地偏离现有和公认的缩写词的既定用法，并导致在未来进行繁琐的组合，这不太可能得到广泛接受。 现在使用的缩略语是出于对长化学名称方便、易于理解的速记的需要而自然产生的。预计这一过程将沿着阻力最小的自然路线继续进行，并将在需要时作为进一步标准化的基础。然而，似乎需要一份编写缩略语的通用指南，以促进未来更具组织性和统一性的标准化。随附附录，其中提出了编写缩写词的统一方法。 1.5注意，大写字母F应用于指定磷酸盐，其他元素也可指定为F。 1.6提供了缩写词（FR）和代码编号，以识别用作添加到塑料中的阻燃剂的材料类别。该系统用于需要标记塑料产品的情况。 注释2 — ISO 1043第1部分至第3部分中的许多缩写术语、代码、数字和符号 ISO/DIS 1043-4 与ASTM D1600中的相应项目相同。D1600包括许多ISO 1043中没有的缩写术语 .

1.1 The purpose of this terminology is to provide uniform contractions of terms relating to plastics. Abbreviated terminology has evolved through widespread common usage. This compilation has been prepared to avoid both the occurrence of more than one abbreviated term for a given plastics term and multiple meanings for abbreviated terms. 1.2 The scope of these abbreviated terms includes plastics terms pertaining to composition and relating to type or kind according to mode of preparation or principle distinguishing characteristics. Also included are abbreviated terms for terms relating to copolymers, blends and alloys of plastics, and additives such as plasticizers, fillers, etc. Note 1 — A code relating to the composition of rubbers is given in Practice D1418 . 1.3 No attempt is made here to systematize formally a shorthand terminology for polymers. Terminology, including nomenclature, codes, symbols, and formula designations for use in scientific literature in the field of natural and synthetic polymers, are being studied and standardized by the International Union of Pure and Applied Chemistry. 2 1.4 These abbreviated terms are by no means all-inclusive of plastics terminology. They represent, in general, those terms that have come into established use. Since it is recognized that abbreviated terms serve no useful purpose unless they are generally accepted and used, no attempt has been made to establish a rigorous code for devising standard abbreviated terms. This would result in awkward departures from established usage of existing and accepted abbreviated terms and lead to cumbersome combinations in the future, which would not be likely to receive widespread acceptance. The abbreviated terms now in use have grown naturally out of the need for convenient, readily comprehended shorthand for long chemical names. This process can be expected to continue along the natural lines of least resistance and will serve as a basis for further standardization as the need arises. A general guide for the preparation of abbreviated terms appears desirable, however, to facilitate more organized and uniform standardization in the future. An appendix is attached, which suggests a uniform way to prepare abbreviated terms. 1.5 Note that the uppercase letter F should be used to designate phosphate and that other elements may also be designated F. 1.6 An abbreviated term (FR) and code numbers are provided to identify classes of materials used as flame retardants added to plastics. The system is provided for use in situations where marking of plastics products is desired. Note 2 — Many of the abbreviated terms, codes, numbers, and symbols in ISO 1043 parts 1 through 3 and in ISO/DIS 1043-4 are the same as the corresponding item in ASTM D1600. D1600 includes a number of abbreviated terms that are not in ISO 1043 .
