This part of ISO 4491 describes a method for determining the total content of oxygen in the metal powders by reduction and high-temperature extraction. This method is also applicable, by agreement, to the determination of the total oxygen content in the sintered metal materials. This method is applicable to all metals, alloys, carbides and mixtures thereof provided they are not volatile under the conditions tested. The sample may be in powder or compact. Analysis is performed in the dust as delivered, but the method is not applicable if the dust contains binders or lubricants. If such substances are present, the method can only be used if previously can be removed from the total way by a method that does not affect the oxygen content of the powder. This part of ISO 4491 Standard should be used in conjunction with ISO 4491-1.
