1.1 本说明书涵盖了用于确定由生产商提供的铸造或锻造镍、镍合金和钴合金部件和/或材料的化学组成的可接受性的变化限制。目前未在此列出的元素或元素范围的检查分析限度应在适用的材料质量标准中规定或由买方和供应商商定。 1.2 如果有任何冲突的要求，采购订单的要求、单个材料规格和本通用规格应按指定的顺序为准。 1.3 当在材料规范中特别提及时，买方可以选择在其最终验收或验证程序中应用检查分析限度来确定可接受性。检查分析限值不允许或不允许由生产商用于其自己的钢包或钢锭分析验收测试。1.4 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。 1.5 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》中确立的国际公认的标准化原则制定的。

1.1 This specification covers limits of variation for determining acceptability of the chemical composition of cast or wrought nickel, nickel alloy, and cobalt alloy parts and/or material supplied by a producer. Check analysis limits for elements or for ranges of elements not currently listed herein shall be as specified in the applicable material specification or as agreed upon by purchaser and supplier. 1.2 In case of any conflicting requirements, the requirements of the purchase order, the individual material specification, and this general specification shall prevail in the sequence named. 1.3 When specifically referenced in the material specification, the buyer may elect to apply check analysis limits to determine acceptability at his final acceptance or verification procedures. Check analysis limits are not permitted or are to be used by the producer for their own ladle or ingot analysis acceptance testing. 1.4 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. 1.5 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.
