1.1 This specification covers additive manufacturing of components via full-melt powder bed fusion processing of titanium alloys. Components made using this processing method are typically used in applications that require mechanical properties similar to wrought products. Products built to this specification may require additional post-processing in the form of machining, polishing, etc., to meet necessary surface finish and dimensional requirements. 1.2 This specification is intended for the use of purchasers or producers, or both, of additively manufactured titanium 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 committee members. 1.4 User requirements considered more stringent may be met by the addition to the purchase order of one or more supplementary requirements, which include, but are not limited to, those listed in Supplementary Requirements S1-S16. 1.5 The values stated in SI units are to be regarded as the standard. Other units are included only for informational purposes. 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.
