1.1本指南是用于描述聚合物颗粒缺陷的术语汇编。术语中普遍理解或充分定义的术语 D883 或其他现成的来源不包括在内。 1.2并非每个术语都适用于每种类型的颗粒。例如，适用于透明颗粒的术语并不总是适用于半透明或不透明颗粒。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 笔记 1-没有已知的ISO等效于本指南。 ====意义和用途====== 本指南旨在为聚合物颗粒的供应商和用户提供术语，以确保在讨论颗粒缺陷时相互理解。 这不是一个绝对标准，但在聚合物材料的质量和/或描述出现问题时可参考。 本指南根据最适合该术语及其描述进行分类，以便于找到某些描述类型。 本指南中的某些术语不适用于所有树脂类型。它是用户 ’ 确定该术语及其后续定义是否适用于相关材料的责任。 本文件中未包含的与聚合物相关的其他术语可在其他标准（如术语）中找到 D883 .

1.1 This guide is a compilation of terms used to describe defects of polymeric pellets. Terms that are generally understood or defined adequately in Terminology D883 or in other readily available sources are not included. 1.2 Not every term is applicable to every type of pellet. Terms which apply to transparent pellets, for example, do not always apply to translucent or opaque pellets. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Note 1—There is no known ISO equivalent to this guide. ====== Significance And Use ====== This guide is intended to provide terminology for both suppliers and users of polymer pellets to ensure mutual understanding in discussions concerning pellet defects. It is not an absolute standard but is to be referred to when issues with the quality and/or description of the polymeric materials arise. The guide is categorized according to the best fit for the term and its description for ease of finding certain description types. Some terms within this guide do not apply to all resin types. It is the user ’ s responsibility to determine if the term and its subsequent definition are applicable to the material in question. Other terminology relating to polymers that are not included in this document can be found in additional standards such as Terminology D883 .
