1.1 本规范涵盖聚醚酮酮材料，通常称为PEKK，适用于成型、挤压、复合材料、粉末涂料和增材制造。本规范仅涵盖6-8级材料。该分类系统提供了使用再研磨或再加工材料的要求。 1.2 本规范涵盖以颗粒和粉末形式提供的热塑性树脂材料。 1.3 本规范仅适用于PEKK共聚物，不含任何额外的填料或无机添加剂、合金或属性改性处理。 1.4 本分类系统和随后的标注（规范）旨在提供标注最终产品或零件制造中使用的聚醚酮材料的方法。 1.5 聚（醚酮）（PEKK）是聚（芳基醚酮）或PAEK聚合物家族的成员。PEKK具有广泛的间苯二甲酰基和对苯二甲酰重复单元的重复单元组合。本标准对聚合物选项进行了分类。 1.6 IEEE/ASTM S-10中详细说明的以国际单位制表示的值应视为标准。括号中给出的值仅供参考。 1.7 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。 注2: PEKK是一种热塑性聚合物。测试条件可能会影响技术结果。采用不同于本规范规定的技术制备的试样可能具有与规定值不同的特性。 1.8 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 specification covers poly(ether ketone ketone) materials, commonly referred to as PEKK, which are suitable for molding, extrusion, composites, powder coating and additive manufacturing. Only materials in this Class 6-8 are covered by this specification. This classification system provides requirements for the use of regrind or reprocessed materials. 1.2 This specification covers thermoplastic resin materials supplied in pellet as well as powder form. 1.3 This specification applies only to PEKK copolymers, without any additional fillers or inorganic additives, alloys, or treatments for modification of attributes. 1.4 This classification system and subsequent line callout (specification) are intended to provide means of calling out poly(ether ketone ketone) materials used in the fabrication of end items or parts. 1.5 Poly(ether ketone ketone) (PEKK) is a member of the poly (aryl ether ketone) or PAEK polymer family. PEKK has a broad range of repeat unit combinations of Isophthaloyl and Terephthaloyl repeat units. This standard classifies the polymer options. 1.6 The values stated in SI units, as detailed in IEEE/ASTM S-10, are to be regarded as the standard. The values given in parentheses are for information only. 1.7 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. Note 2: PEKK is a thermoplastic polymer. Testing conditions can affect the technical results. Specimens prepared by techniques different than prescribed in this specification can have properties that vary from the values specified. 1.8 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.
