1.1 该分类系统涵盖适用于注塑和挤出的液晶聚合物（LCP）材料。该分类系统允许使用回收、重构、回收再研磨、回收或再加工的液晶聚合物，或其组合，前提是满足该分类系统中规定的要求。液晶聚合物的供应商和买方有责任确保合规性，这些聚合物可回收、重构、回收、再研磨、回收或再加工，或其组合。 1.2 本分类系统中包含的财产是识别所涵盖成分所需的属性。 允许有其他必要的要求来识别对专门应用程序很重要的特定特性。这些应由用户和供应商通过使用第节中给出的后缀达成一致 5. . 1.3 该分类系统和随后的线条标注（规范）旨在作为一种标注最终用途物品或零件制造中使用的塑料材料的方法。它不用于材料的选择。在仔细考虑了零件所需的设计和性能、零件所处的环境、所采用的制造工艺、所涉及的成本以及除本分类系统所涵盖的材料以外的其他材料的固有财产后，塑料领域的专业人士可以选择材料。 1.4 以国际单位制表示的数值应视为标准。 1.5 以下注意事项仅适用于试验方法部分，第节 11 ，属于该分类系统: 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 注1: 目前还没有与该标准等效的ISO。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

1.1 This classification system covers liquid crystal polymeric (LCP) materials suitable for injection molding and extrusion. This classification system allows the use of liquid crystal polymers that are recycled, reconstituted, recycled-regrind, recovered, or reprocessed, or a combination thereof, provided that the requirements as stated in this classification system are met. It is the responsibility of the supplier and the buyer of liquid crystal polymers that are recycled, reconstituted, recycled-regrind, recovered, or reprocessed, or a combination thereof, to ensure compliance. 1.2 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 allowed. These shall be agreed upon between the user and the supplier, by using suffixes as given in Section 5 . 1.3 This classification system and subsequent line callout (specification) are intended to be a means of calling out plastic materials used in the fabrication of end-use items or parts. It is not intended for the selection of materials. Material selection can be made by those having expertise in the plastics field after careful consideration of the design and the performance required of the part, the environment to which it will be exposed, the fabrication process to be employed, the costs involved, and the inherent properties of the material other than those covered by this classification system. 1.4 The values stated in SI units are to be regarded as standard. 1.5 The following precautionary caveat pertains only to the test method portion, Section 11 , 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: There is no known ISO equivalent to this standard. 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.
