Scope

This part of JB/T 6326 specifies the reagents, analysis procedures, calculation of analysis results and precision of the aluminum content of nickel-chromium and nickel-chromium iron alloys using the chromium azure S photometric method. This section applies to the determination of aluminum content in nickel-chromium and nickel-chromium iron alloys. Measuring range: 0.050% ~ 0.500%. This section is also a special case for the configuration of the reference solution and the color solution when the masking agent used for the determination of aluminum content in nickel-chromium iron alloys is cyclohexanediaminetetraacetic acid-zinc solution. The measurement range is 0.050%~0.500%.
