UNE-EN ISO 4491-2:2024 Metallic powders - Determination of oxygen content by reduction methods - Part 2: Loss of mass on hydrogen reduction (hydrogen loss) (ISO 4491-2:2023)
This standard provides a method for determining the oxygen content in metallic powders through reduction by hydrogen. Specifically, it details how to measure mass loss during the process of hydrogen reduction as an indicator of oxygen content. This approach is part of a series addressing various methods for assessing the quality and characteristics of metallic powders.
