范围：1.1 This test method covers the determination of the mass of hydrogen-reducible constituents in the following metal powders: cobalt, copper, iron, and tungsten. 1.2  This test method is useful for cobalt, copper, and iron powders in the range from 0.05 to 3.0 % oxygen, and for tungsten powder in the range from 0.01 to 0.50 % oxygen. 1.3 This  test method does not measure the oxygen contained in oxides such as silicon  oxide (SiO2), aluminum oxide (Al2O3), magnesium  oxide (MgO), calcium oxide (CaO), titanium dioxide (TiO2), etc. that are not reduced by hydrogen at the test temperatures.  1.4 For total oxygen  content, vacuum or inert gas fusion methods are available (see Test Methods E1019). 1.5 The values stated in SI units are to be regarded as the standard. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility  of the user of this standard to establish appropriate safety and health practices  and determine 下载：
