Summary
This document specifies a method for determining the relative mass loss experienced by a metal powder when heated in a stream of pure, dry hydrogen under specified conditions. This test evaluates a chemical characteristic of powders that is important in the powder metallurgy industry. The test is not intended to determine the content of certain specific elements (see Annex A and ISO 4491-1). This test method is applicable to unalloyed, partially or fully alloyed powders based on the metals indicated in Table 1 (see 7.2.1). It is not applicable to powders containing lubricant or mixtures of metal powders.
