1.1 本规范涵盖四种尺寸复合压力管的带开口环和压缩螺母的金属插入配件（压缩接头）以及带铜压接环的金属插入接头（压接接头）。这些配件适用于125 psi（690 kPa）的冷水和热水分配系统，其运行温度高达180 华氏度（82 °C）。（当用于聚乙烯/铝/聚乙烯系统时，管道的最高工作温度限制为140 °F（60 °C），适用时180 华氏度（82 °C））。包括材料、工艺、爆破压力、持续压力、过高温度和压力、温度循环试验以及配件和环上使用的标记的要求。本规范涵盖的配件适用于住宅和商业应用的饮用水分配系统、供水、地下灌溉系统和辐射板供暖系统、底板、雪地- 以及与复合管和配件兼容的气体。 1.2 以英寸磅为单位的数值应视为标准。括号中给出的值是国际单位制的数学转换，仅供参考，不被视为标准。 注1: 表中显示了以毫米为单位的“标称尺寸”，括号内为英寸尺寸。这一例外是为了使“标称尺寸”与两个管道标准规范相协调 F1281美元 和 第1282页 。 1.3 以下注意事项仅适用于试验方法部分，第节 9 ，本规范的。 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。 1.4 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 metal insert fittings with split ring and compression nut (compression joint) and metal insert fittings with copper crimp rings (crimp joint) for four sizes of composite pressure pipe. These fittings are intended for use in 125 psi (690 kPa) cold- and hot-water distribution systems operating at temperatures up to and including 180 °F (82 °C). (When used in polyethylene/aluminum/polyethylene systems the maximum operating temperature is limited by the pipe to 140 °F (60 °C) and where applicable 180 °F (82 °C)). Included are the requirements for materials, workmanship, burst pressure, sustained pressure, excessive temperature and pressure, temperature cycling tests, and markings to be used on the fittings and rings. The fittings covered by this specification are intended for use in potable water distribution systems for residential and commercial applications, water service, underground irrigation systems, and radient panel heating systems, baseboard, snow- and ice-melt systems, and gases that are compatible with the composite pipe and fittings. 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. Note 1: The tables show the “nominal size” in millimetres with the inch size in parentheses. This exception is made to harmonize the “nominal size” with the two pipe standards, Specifications F1281 and F1282 . 1.3 The following precautionary caveat pertains only to the test method portion, Section 9 , 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. 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.
