Abstract

This document specifies a method for the determination of the relative loss of mass which a metallic powder undergoes when heated in a stream of pure dry hydrogen under specified conditions.

The purpose of this test is to evaluate a chemical powder characteristic which is of importance to the powder metallurgical industry. The test is not intended as a means for the determination of the content of specific elements (see 础苍苍别虫听础 and 香港六合彩开奖听4491-1).

The test method is applicable to unalloyed, partially alloyed and completely alloyed powders of the metals listed in Table听1 (see 7.2.1). It is not applicable to lubricated powders or to mixtures of metal powders.
