【国外标准】 Standard Specification for Powder Bed Fusion of Plastic Materials

This specification applies to plastic parts that are created using powder bed fusion processes, including unfilled formulations and formulations containing fillers, functional additives (for example, flame retardant), and reinforcements or combinations thereof. The requirements are intended for use by manufacturers of plastic parts using powder bed fusion and for customers procuring such parts. The specification covers process classification, ordering information, materials (material specification and virgin powder), fabrication of test specimens, and material processing. Dimensional tolerances, source inspection, retest and rejection of parts, material and process certification, certification for parts, and identification marking of product are also specified, together with part packaging and package marking. A figure presents the specifications for mechanical testing of powder bed fusion polymer parts.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.
