1.1 本规范涵盖了降低电镀、自催化电镀、搪瓷、化学转化涂层、磷化和相关预处理过程中可能出现的氢脆或降解易感性或易感性的程序。本规范适用于那些性能不会因190℃烘烤而受到不利影响的钢 °C至230 °C或更高（参见 6.1.1 )。 1.2 本文建立的热处理程序已被证明可有效降低抗拉强度为1000MPa或更高的钢部件的敏感性，这些钢部件在热处理后已被机械加工、研磨、冷成型或冷矫直。该热处理程序在任何能够给零件充氢的操作之前使用，例如电镀、自催化电镀、搪瓷和其他化学涂层操作之前的清洁程序。 注1: 1兆帕 = 145.1磅/平方英寸。 1.3 本规范已与ISO/DIS 9587进行了协调，在技术上是等效的。 1.4 以国际单位制表示的数值应视为标准。 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。 1.6 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 procedures for reducing the susceptibility or degree of susceptibility to hydrogen embrittlement or degradation that may arise in electroplating, autocatalytic plating, porcelain enameling, chemical conversion coating, and phosphating and the associated pretreatment processes. This specification is applicable to those steels whose properties are not affected adversely by baking at 190 °C to 230 °C or higher (see 6.1.1 ). 1.2 The heat treatment procedures established herein have been shown to be effective for reducing the susceptibility of steel parts of tensile strength 1000 MPa or greater that have been machined, ground, cold-formed, or cold-straightened subsequent to heat treatment. This heat-treatment procedure is used prior to any operation capable of hydrogen charging the parts, such as the cleaning procedures prior to electroplating, autocatalytic plating, porcelain enameling, and other chemical coating operations. Note 1: 1 MPa = 145.1 psi. 1.3 This specification has been coordinated with ISO/DIS 9587 and is technically equivalent. 1.4 The values stated in SI units are to be regarded as 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.
