Scope
GB/T 41335-2022 is the English-translated version of 增材制造用镍粉.
GB/T 41335-2022 is the Chinese national standard for the nickel powders used in additive manufacturing.
It gives the classification, the technical requirements - the chemical composition, the particle size distribution, the morphology, the flowability, the apparent and tap density and the oxygen content - the test methods, the inspection rules, the provisions on marking, packaging, transport and storage, the accompanying documents and the contents of an order.
It applies to nickel powder for additive manufacturing, where the behaviour of the powder decides the soundness of the printed part. Powder producers and the shops that print with them use it. Issued on 9 March 2022, it has applied since 1 October 2022.
