With additive manufacturing technology entering the stage of large-scale production, quality inspection of additively manufactured products has become a major concern. Laser powder. The transition from research and development to batch production of bed-melted metal parts generally involves stages such as metal part qualification, first article inspection, and batch production delivery. The qualification stage typically requires... Conduct comprehensive functional and performance tests to verify the rationality of the metal component manufacturing process and whether its functional and performance characteristics meet the mission requirements. The testing involves numerous items and a long cycle; the first article stage generally only tests the performance of metal parts for conformity testing and production capacity assessment, and is separate from qualification testing. Compared to previous stages, the number of testing items can be significantly reduced; in the batch production and delivery stage, performance testing of metal parts can be completed through random sampling to evaluate... Compared to the first article test, the number of inspection items and samples can be further reduced to ensure production stability. Therefore, the inspection requirements for large-scale production are... There are significant differences between the research and development stages. If the testing requirements from the research and development stage are directly adopted, there will be problems such as a large number of testing items, high costs, and long cycles. This document is formulated to address the issues of high testing costs and long testing cycles for additively manufactured metal parts produced on a large scale. It is based on the characteristics of metal parts in... The degree of damage caused during use is used to classify the quality of laser powder bed molten metal parts, based on the process from research and development to mass production. The process is categorized into stages, clarifying the testing requirements for different levels and categories of metal parts, and guiding customers and suppliers in the testing of additive manufacturing metal parts. Conducting reasonable testing can effectively evaluate the quality of metal parts while reducing testing costs. This document, as the first domestic standard for quality grading and testing requirements of laser powder bed molten metal parts for large-scale production, will complete... A sound additive manufacturing testing standard system will provide technical support for related enterprises and testing institutions in the industry chain, and promote the development of laser powder bed molten metal parts. Large-scale application and high-quality development of the industry. Additive manufacturing of laser powder bed molten metal parts Quality grading and testing requirements

1 Scope

GB/T 47006-2026 is the Chinese national standard covering grading a printed metal part - the levels of internal soundness, dimensional accuracy and surface condition, and what has to be tested to claim each, which is how a buyer specifies quality without specifying the machine. First edition, with the endoscopic inspection atlas GB/T 47008-2026 and the titanium deposition specification GB/T 47005-2026. It was issued on 28 January 2026 and has been in force since 1 August 2026, as a first edition. The document is under the responsibility of the China Machinery Industry Federation. This page is published from the official record of the 2026 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.
