Other Titles Withdrawn Description Printed version of this standard is available at Library. To request, please e-mail to referencepk@usm.my and include a copy of this record in your e-mail. Abstract This part of ISO 4491 specifies a method for the determination of the total oxygen content of metallic powders in concentrations up to about 2 % (m/m) by reduction extraction at high temperature. By agreement, this method is also applicable to the determination of the total oxygen content of sintered metal materials. The method is applicable to all powders of metals, alloys, carbides and mixtures thereof which are non-volatile under thetest conditions. The sample may be in powder or compact form. The analysis is carried out on the powder as supplied, but themethod 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. This part of ISO 4491 shall be read in conjunction with ISO 4491-1.
