BS EN ISO 4497:2020 PDF

Scope: What is ISO 4497 about? ISO 4497 specifies a method of determining the particle size distribution of metallic powders by dry sieving into size fractions. The method is applicable to dry, unlubricated metallic powders, but not applicable to powders in which the morphology differs markedly from being equiaxial, for example, flake-type powders. The method does not apply to metallic powders having a particle size wholly or mostly under 45 μm. Who is ISO 4497 for? ISO 4497 on metallic powders is beneficial for Metallurgist Metal industries Metal testing laboratories and R&D Mechanical Engineer Why should you use ISO 4497 ? The dry sieving method is used to determine the particle size of metallic powder. ISO 4497 provides information on test equipment, preparation of test portion, test procedure, and test report on the particle size of metallic powder using the dry sieving method. As a user of ISO 4497, you can ensure the particle size of metallic powder by the dry sieving method this helps the user to improve the surface quality of metal. What’s changed since the last update? BS EN ISO 4497:2020 supersedes BS EN 24497:1993 , which is withdrawn. The main changes compared to the previous edition is as follows: Inclusion of a precision statement.
