1.1 该分类系统仅涵盖适用于注塑和挤出的ABS材料和ABS合金。这些组合物中的一些也适用于压缩模塑。 1.2 该分类系统和随后的线条标注（规范）旨在提供一种方法，用于标注制造最终产品或零件时使用的塑料材料。它不用于选择材料。材料应由在塑料领域具有专业知识的人员进行选择，选择时应考虑经济性、所遇到的环境、材料的固有财产、零件设计、所需的零件性能和所采用的制造工艺。 1.3 本分类系统中包含的财产是识别所涵盖成分所需的属性。通过使用第节中给出的后缀来解决识别对专业应用重要的特定特性所需的其他要求 5. . 1.4 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 1.5 以下预防性警告仅适用于测试方法部分，第节 12 ，属于该分类系统: 本标准并不旨在解决与其使用相关的所有安全问题（如有）。 本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 注1: 本标准和ISO 19062涉及相同的主题，但技术内容不同。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。

1.1 This classification system covers only ABS materials and ABS alloys suitable for injection molding and extrusion. Some of these compositions are also suitable for compression molding. 1.2 This classification system and subsequent line callout (specification) are intended to provide a means of calling out plastic materials used in the fabrication of end items or parts. It is not intended for the selection of materials. Materials are to be selected by personnel with expertise in the plastics field where the economics, the environment to be encountered, the inherent properties of the materials, the part design, the part performance required, and the manufacturing process to be employed all enter into the selection. 1.3 The properties included in this classification system are those required to identify the compositions covered. Other requirements necessary to identify particular characteristics important to specialized applications are addressed by using the suffixes given in Section 5 . 1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.5 The following precautionary caveat pertains only to the test methods portion, Section 12 , of this classification system: 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Note 1: This standard and ISO 19062 address the same subject matter, but differ in technical content. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
