1 Scope
This part specifies the determination methods for oxygen content in copper and copper alloys.
This part is applicable to the determination of oxygen content in copper and copper alloys. The determination range is 0.00030% ~ 0.11%.
2 Principle
Put the prepared test portion in to a carbon crucible that had been degassed at high temperature, and heat the portion until melting under helium (or argon) so that the oxygen in such portion is separated out of the metal as carbon monoxide or is separated out, passing through a 400℃ rare earth copper oxide furnace along with the helium (argon) for conversion, as carbon dioxide. Import into an infrared detector for the determination and the mass of oxygen is automatically indicated by the computer.
