Scope

This standard specifies the method of high-temperature reduction-extraction determination of the total oxygen content in metal powders not greater than 2% (mass fraction). This standard applies to various metals, alloys, carbides (tungsten carbide) and mixture powders that have no volatile components under the test conditions. It can also be used to determine the total oxygen content in sintered metal materials. Samples can be powdered or briquetted. Powders are analyzed as supplied. This method is not suitable for powders containing lubricants or binders. If the sample contains lubricants or binders, this method should only be used if these substances are first completely removed by a method without affecting the oxygen content.
