发布日期: 2024-04-01
1.1 本规范涵盖三氟氯乙烯、全氟烷氧基和四氟乙烯的共聚物,适用于挤出、压缩和注射成型。 1.2 本规范不包括混合材料,也不包括再生材料。 1.3 以国际单位制表示的数值详见 IEEE/ASTM SI-10 被视为标准。括号中给出的值仅供参考。 1.4 以下安全隐患警告仅适用于试验方法部分,第节 11 。 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: 尽管这个分类系统和ISO 20568-1和ISO 20568-2在方法或细节上有所不同,使用其中一种方法获得的数据在技术上是等效的。 1.5 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 copolymers of chlorotrifluoroethylene, perfluoroalkoxy, and tetrafluoroethylene and are suitable for extrusion, compression, and injection molding. 1.2 This specification does not cover blended materials and does not cover recycled materials. 1.3 The values stated in SI units as detailed in IEEE/ASTM SI-10 are to be regarded as the standard. The values given in parentheses are for information only. 1.4 The following safety hazards caveat pertains only to the test method portion, Section 11 , of this specification. 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: Although this classification system and ISO 20568-1 and ISO 20568-2 differ in approach or detail, data obtained using either are technically equivalent. 1.5 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.
