Method for determination of flow rate of metal powders
Lubricated metallic powders; Determination of lubricant content; Soxhlet extraction method
Specifies symbols and designations, apparatus, preparation of test- pieces, procedure and test report. Figures show the different phases.
Hardmetals; Metallographic determination of microstructure
The method is applicable to carbide and binder metal powder mixtures, free of lubricant, and all grades of presintered or sintered hardmetals, with a titanium content exceeding 0,2 % (m/m). Specifies principle, interfering elements, reagents, apparatus, sample preparation, procedure, elimination of interferences, preparation of the calibration curve, expression of results and test report.
Hardmetals; Determination of titanium; Photometric peroxide method
Relates to the sampling and testing of powder mixtures for the manucacture of hardmetals, using sintered test pieces, and to the preparation of test pieces.
Hardmetals; Sampling and testing of powders using sintered test pieces
Applies to the determination of the physical and mechanical properties of sintered hardmetals. Defines the terms "lot" and "test sample" and specifies test report.
Sintered hardmetals; Sampling and testing
The solution method determines cobalt, iron, manganese, molybdenum, nickel, niobium, tantalum, titanium, tungsten, vanadium and zirconium. Is applicable to carbides of niobium, tantalum, titanium, vanadium, tungsten and zirconium, mixtures of these carbides and binder metals, all grades of presintered or sintered hardmetals, produce from these carbides, with the minimum element contents shown in table 1.
Hardmetals; Determination of contents of metallic elements by X-ray fluorescence; Solution method
Specifies methods for the determination of the presence, type, and distribution of porosity and uncombined carbon in hardmetals, furthermore apparatus, preparation of test pieces, procedure and test report. Figures show the types of apparent porosity and uncombined carbon.
