1.1 本规范涵盖了用于制造钛合金植入物涂层的非合金钛和Ti-6Al-4V合金粉末的要求。 1.2 本规范涵盖的粉末可用于通过烧结或热喷涂技术形成涂层。 1.3 本规范仅涵盖粉末要求。它不涉及由其形成的涂层的特性。 1.4 细碎的钛粉可能被认为是自燃的，应根据适当的指南进行处理。 1.5 单位- 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值可能不是精确的等效值；因此，每个系统应相互独立使用。将两个系统的值合并可能会导致不符合标准。 1.6 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 the requirements for unalloyed titanium and Ti-6Al-4V alloy powders for use in fabricating coatings on titanium alloy implants. 1.2 Powders covered under this specification may be used to form coatings by sintering or thermal spraying techniques. 1.3 This specification covers powder requirements only. It does not address properties of the coatings formed from them. 1.4 Finely divided titanium powder may be considered pyrophoric and should be handled in accordance with the appropriate guidelines. 1.5 Units— The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 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.
