1.1 本规范规定了最大允许工作压力为300磅/平方英寸（300磅/平方英寸）[2.07兆帕]的管道系统中使用的金属压接配件所需的性能特征。这些配件通过管道或管件或其组合的机械变形直接连接到管道或管件，形成密封和约束接头。密封可以通过（管道、管子或配件的）机械变形创建，也可以独立创建。本文所述测试的成功完成构成鉴定过程技术部分的完成。 1.2 规定的试验仅适用于确定性能特性。这些试验不用于评估非压接配件。 1.3 有关金属压接配件的应用，请参阅IACS UR P2.7.4，表7。 1.4 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值可能不是精确的等效值；因此，每个系统应相互独立使用。将两个系统的值合并可能会导致不符合标准。 1.5 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。 1.6 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 establishes the performance characteristics required for Metallic Press-Connect Fittings for use in piping and tubing systems with a maximum allowable working pressure of three-hundred pounds per square inch (300 psi) [2.07 MPa]. These fittings directly attach to pipe or tube by mechanical deformation of the pipe or tube or fitting, or a combination thereof, creating a seal and a restrained joint. The seal may be created via the mechanical deformation (of the pipe, tube or fitting) or created independently. Successful completion of the tests described herein constitutes completion of the technical portion of the qualification process. 1.2 The tests specified are applicable only to ascertain the performance characteristics. These tests are not intended for use in the evaluation of non-Press-Connect Fittings. 1.3 Refer to IACS UR P2.7.4, Table-7 for Metallic Press-Connect Fittings applications. 1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.5 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. 1.6 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.
