1.1 本规范规定了最大允许工作压力为每平方英寸300磅（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或配件的机械变形或其组合直接附接到管道或管，从而产生密封和约束接头。密封可以经由(管、管或配件的)机械变形产生或独立地产生。成功完成本文所述的测试构成确认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征。这些测试不用于评估非压接配件。 1.3 有关金属压接接头应用，请参见IACS UR P2.7.4表-7。 1.4 以SI单位或英寸-磅单位表示的值应单独视为标准值。每个系统中陈述的值不一定完全等同；因此，为确保符合标准，每个系统应独立使用，两个系统的数值不得合并使用。 1.5 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。 1.6 本国际标准是根据国际公认的标准化原则制定的世界贸易组织技术性贸易壁垒委员会。

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 are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 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.
