This section Method Three identical with ISO 7266. 1984 "Copper and copper alloys - Determination of sulfur content - Combustion titration method", compared with the original International Standard
We made the following editorial changes.
--- With a decimal point instead of a comma as the decimal point in the international standard ",". ",";
--- Use the "method" instead of "this International Standard";
--- Revised international standard-Africa legal units of measurement;
--- The formula, reg number, table number to re-annotate;
--- Remove the cover of the international standards, directory, foreword and introduction.
This Part replaces GB/T 5121.4-1996 "Copper and copper alloys - Determination of the amount of carbon and sulfur" and GB/T 13293.13-
1991 "high purity copper cathode chemical analysis of combustion - potassium iodate titration method for the determination of sulfur content."
This portion of the GB/T 5121.4-1996 have the following main changes and GB/T 13293.13-1991 compared.
--- One method of GB/T 5121.4-1996 revision, complementing the quality assurance and control provisions, increasing the precision of the terms;
--- Second method is GB/T 13293.13-1991 amendments. Measured by the scope of 0.0004% ~ 0.0030% revised to
0.0004% to 0.0020% supplemented with quality assurance and control provisions, increasing the precision of the terms;
--- Adds three. 1984 "Copper and copper alloys - Determination of sulfur content --- --- combustion titration method". identical with the international standard ISO 7266.

Copper and copper alloys -
The determination of carbon, sulfur content. Part 4
1 a method of high frequency infrared absorption method
1.1 Scope
This method specifies the method for determination of copper and copper alloy of carbon and sulfur content.
This method is applicable to the determination of copper and copper alloy of carbon and sulfur content. Measurement range. 0.0010% to 0.20% carbon; Sulfur 0.0010% to 0.030%.
