Scope: This standard specifies the method for the determination of oxygen that can be reduced by hydrogen in metal powders with an oxygen content (mass fraction) of 0.05% to 3%. This method is applicable to unalloyed, partially alloyed and fully alloyed metal powders, as well as mixtures of carbides and binder metals. It is not suitable for powders containing lubricants or organic binders. By using a dedicated catalytic device, the method can be extended to measure carbon-containing powders. ISO 4491 should be read together with ISO 760 and ISO 4491-1.
