1.1 本规范涵盖使用全熔粉末床熔合（如电子束熔合和激光熔合）额外制造的钛-6Al-4V（Ti-6Al-4V）组件。通过这些工艺生产的部件通常用于要求机械性能类似于机加工锻件和锻造产品的应用中。根据本规范制造的部件通常（但不一定）通过机加工、磨削、放电加工（EDM）、抛光等进行后处理，以达到所需的表面光洁度和关键尺寸。 1.2 本规范旨在供额外制造的Ti-6Al-4V部件的购买者或生产者（或两者）使用，以定义要求并确保部件性能。 1.3 建议用户使用本规范作为获取满足委员会成员协商一致确定和修订的最低验收要求的组件的基础。 1.4 在采购订单中添加一个或多个补充要求可以满足被认为更严格的用户要求，这些补充要求可能包括但不限于S1-S16中列出的要求。 1.5 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.6 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。 1.7 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 covers additively manufactured titanium-6aluminum-4vanadium (Ti-6Al-4V) components using full-melt powder bed fusion such as electron beam melting and laser melting. The components produced by these processes are used typically in applications that require mechanical properties similar to machined forgings and wrought products. Components manufactured to this specification are often, but not necessarily, post processed via machining, grinding, electrical discharge machining (EDM), polishing, and so forth to achieve desired surface finish and critical dimensions. 1.2 This specification is intended for the use of purchasers or producers, or both, of additively manufactured Ti-6Al-4V components for defining the requirements and ensuring component properties. 1.3 Users are advised to use this specification as a basis for obtaining components that will meet the minimum acceptance requirements established and revised by consensus of the members of the committee. 1.4 User requirements considered more stringent may be met by the addition to the purchase order of one or more Supplementary Requirements, which may include, but are not limited to, those listed in S1-S16. 1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6 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. 1.7 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.
