Metallic powders. Determination of oxygen content by reduction methods - General guidelines1 Scope This part of ISO 4491 is the first part of a series dealing with the determination of oxygen content in metallic powders by reduction methods. It gives general guidance to these methods, and gives some recommendations for the correct interpretation of the results obtained. The test methods are applicable generally to all powders of metals, alloys, carbides and mixtures thereof. The constituents of the powder shall be non volatile under the

Products can only be tested at a concentration of 80 % or less (97 % with a modified method for special cases) as some dilution is always produced by adding the test organisms and interfering substance

This can result in knock-off quality products with a poor finish and build quality and even less safety
