1.1 本规范描述了一种方法，用于定义使用粉末床熔合工艺制造的塑料零件的要求并确保其组件完整性。材料包括未填充配方和含有填料、功能添加剂（例如，阻燃剂）和增强材料或其组合的配方。工艺包括术语中定义的所有粉末床熔合工艺 F2792 . 1.2 本规范旨在供使用粉末床熔接的塑料零件制造商和采购此类零件的客户使用。 1.3 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不一定是精确的等价物；因此，为确保符合本标准，每个系统应独立使用，且两个系统的值不得组合。 1.4 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。 1.5 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》中确立的国际公认标准化原则制定的。

1.1 This specification describes a method for defining requirements and ensuring component integrity for plastic parts created using powder bed fusion processes. Materials include unfilled formulations and formulations containing fillers, functional additives (for example, flame retardant), and reinforcements or combinations thereof. Processes include all powder bed fusion processes as defined in Terminology F2792 . 1.2 This specification is intended for use by manufacturers of plastic parts using powder bed fusion and for customers procuring such parts. 1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 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.
