GB/T 4193-1984
ActiveMethod for measuring the density of the fine wire and ribbon of tungsten and molybdenum used in electric light sources and vacuumtubes
电真空器件及电光源用细钨丝、钼丝和薄带密度的测试方法
Application Summary AI generated
This standard specifies a method for measuring the density of fine tungsten and molybdenum wires and ribbons used in electric light sources and vacuum tubes. It is applied in the metallurgy and electronics industries to ensure material consistency and quality control during the production of filaments, cathodes, and other components for incandescent lamps, fluorescent lamps, and vacuum electronic devices. The testing method is critical for verifying that these materials meet the required density specifications for reliable performance in high-temperature and vacuum environments.
