1.1 本规范涵盖了与符合以下规定的五种尺寸的插入配件一起使用的不锈钢夹具 F1807 或 F2159 和交联聚乙烯(PEX)塑料管，其符合 F876 并与符合规范的高温聚乙烯（PE-RT）管一起使用 F2769 这些夹具旨在替代规格的铜合金压接环 F1807 适用于100 psi（689.5 kPa）的冷水和热水分配系统，工作温度高达180°F（82°C）。包括对不锈钢夹具的材料、工艺、尺寸和标记的要求；使夹具变形的要求；适用于PEX管组件和规格 F1807 和 F2159 根据本规范，用变形夹具固定插入件。1.2 以英寸-磅单位表示的值应被视为标准值。括号中给出的值是对SI单位的数学转换，仅供参考，不被视为标准。 1.3 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。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法规限制的适用性。 1.4 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》中确立的国际公认的标准化原则制定的。

1.1 This specification covers stainless steel clamps for use with five sizes of insert fittings that comply with F1807 or F2159 , and cross-linked polyethylene (PEX) plastic tubing that complies with F876 and for use with polyethylene of raised temperature (PE-RT) tubing that complies with Specification F2769 . These clamps are intended as an alternative to the copper-alloy crimp-rings of Specifications F1807 for use in 100 psi (689.5 kPa) cold- and hot-water distribution systems operating at temperatures up to and including 180 °F (82 °C). Included are requirements for materials, workmanship, dimensions and marking of the stainless steel clamps; requirements for deforming the clamps; which apply to assemblies of PEX tubing and Specifications F1807 and F2159 , insert fittings secured with deformed clamps per this specification. 1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.3 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. 1.4 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.
