1.1 本规范 2. 包括镍-铬-铝合金、镍-铬铁合金， 3. 镍铬钴钼合金、镍铁铬钨合金和镍铬钼铜合金，其形式为热加工和冷加工圆形、正方形、六边形、矩形和冷加工线材。 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。 1.3 以下注意事项仅适用于试验方法部分，第节 12 ，本规范的: 本标准并不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熟悉所有危险，包括制造商提供的本产品/材料的适当安全数据表（SDS）中确定的危险，制定适当的安全、健康和环境实践，并在使用前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 2 covers nickel-chromium-aluminum alloy, nickel-chromium-iron alloys, 3 nickel-chromium-cobalt-molybdenum alloy, nickel-iron-chromium-tungsten alloy, and nickel-chromim-molybdenum-copper alloy in the form of hot-finished and cold-worked rounds, squares, hexagons, rectangles, and cold-worked wire. 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 The following precautionary caveat pertains only to the test methods portion, Section 12 , 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 become familiar with all hazards including those identified in the appropriate Safety Data Sheet (SDS) for this product/material as provided by the manufacturer, 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.
