Scope

This document describes the methods for determining the oxygen, nitrogen, and hydrogen contents in copper and copper alloys, including the inert gas fusion-infrared absorption method/thermal conductivity method for determining the oxygen and nitrogen contents, and the inert gas fusion-infrared absorption method or thermal conductivity method for determining the hydrogen content.
This document is applicable to the determination of the oxygen, nitrogen, and hydrogen contents in copper and copper alloys. Method 1 is suitable for the separate or simultaneous determination of the oxygen and nitrogen contents in copper and copper alloys, and Method 2 is suitable for the determination of the hydrogen content in copper and copper alloys. The measurement ranges are shown in Table 1.
