1.1 本规范涵盖可熔融加工的成型和挤出材料，以及聚偏氟乙烯氟塑料（通常缩写为PVDF）的涂层材料 2. 在科学文献中）。本规范涵盖以颗粒或粉末形式提供的热塑性树脂材料。 1.2 本规范仅适用于由偏氟乙烯制备的未净化均聚物，而非共聚物，增强、填充等级或特殊等级，带有添加剂或属性修改处理。 1.3 所涉及的试验旨在为未改性聚偏氟乙烯均聚物树脂的规范提供信息。本规范的目的不是为设计目的提供工程数据。 1.4 聚偏氟乙烯氟塑料在156至180°C（312至356°F）之间熔融，热稳定性高达约370°C（698°F）。( 警告- 在某些条件下，腐蚀性和有毒氟化氢可能会发生演变。） 1.5 以国际单位制表示的数值，详见 IEEE/ASTM S-10 ，将被视为标准。括号中给出的值仅供参考。 注1: 聚偏氟乙烯表现出多态性。 2. 晶体结构的类型和程度随样品的热机械历史而变化。采用不同于本规范规定的技术制备的试样可能具有不同于规定值的特性。 1.6 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、健康和环境实践，并确定监管限制的适用性。 第节给出了具体的预防说明 10 . 注2: 本规范没有等效的ISO标准。本规范中的信息在技术上等同于ISO 12086-1和ISO 12086-2中的相关信息。 1.7 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《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

1.1 This specification covers melt processable molding and extrusion materials, as well as coating materials of poly(vinylidene fluoride) fluoroplastic, commonly abbreviated PVDF (or PVF 2 in scientific literature). This specification covers thermoplastic resin materials supplied in pellet or powder form. 1.2 This specification applies only to the virgin homopolymer prepared from vinylidene fluoride, not copolymers, reinforced, filled grades or special grades with additives or treatments for modification of attributes. 1.3 The tests involved are intended to provide information for specification of unmodified PVDF homopolymer resins. It is not the purpose of this specification to provide engineering data for design purposes. 1.4 PVDF fluoroplastics melt between 156 and 180°C (312 and 356°F) and are thermally stable up to about 370°C (698°F). ( Warning— Evolution of corrosive and toxic hydrogen fluoride can occur under certain conditions.) 1.5 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. Note 1: PVDF exhibits polymorphism. 2 The type and extent of crystalline structure varies with the thermomechanical history of the sample. Specimens prepared by techniques different than prescribed in this specification can have properties that vary from the values specified. 1.6 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. Specific precautionary statements are given in Section 10 . Note 2: There is no equivalent ISO standard for this specification. Information in this specification is technically equivalent to related information in ISO 12086-1 and ISO 12086-2. 1.7 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.
