ABSTRACT:
A standard test specimen for optical emission spectrochemical analysis is prepared by molding into the specimen body finely divided particles consisting essentially of the metal or metal alloy to be analyzed without melting the same and preferably by plastic deformation of such particles. The resultant specimen is homogeneous throughout and stable in quality so that accurate analysis of any of its elements is possible and the suitability of the test material for a given product can be accurately predicted.
