Scope

This document describes methods for determining the oxygen, nitrogen, hydrogen
content in copper and copper alloys, including the determination of oxygen and nitrogen
content using the inert gas melting-infrared absorption/thermal conductivity method, as
well as the determination of hydrogen content using the inert gas melting-infrared
absorption or thermal conductivity method.
This document is applicable to the determination of oxygen, nitrogen, hydrogen content
in copper and copper alloys. Method 1 is applicable to the individual or simultaneous
determination of oxygen and nitrogen content in copper and copper alloys, while
Method 2 is applicable to the determination of hydrogen content in copper and copper
alloys. The determination range is shown in Table 1.
This document does not apply to the determination of oxygen, nitrogen, hydrogen
content in copper and copper alloys with a zinc content greater than 1.0%.
