This document specifies a method for the determination of the total oxygen content of metallic powders by reduction-extraction at high temperature.<\/p>\n

By agreement, this method is also applicable to the determination of the total oxygen content of sintered metal materials.<\/p>\n

The method is applicable to all powders of metals, alloys, carbides, and mixtures thereof which are non-volatile under the test conditions. The sample can be in powder or compact form.<\/p>\n

The analysis is carried out on the powder as supplied, but the method is not applicable if the powder contains a lubricant or binder. If such substances are present, the method may be used only if they can first be completely removed by a method not affecting the oxygen content of the powder.<\/p>\n

This document is to be read in conjunction with ISO 4491\u20111.<\/p>\n
