- Scope
- Personnel using this national standard should have practical experience in formal laboratory work. This part does not point out all possible safety problems. Users are responsible for taking appropriate safety and health measures and ensuring compliance with relevant national laws and regulations. This part of GB/T 4497 specifies the method for determining the total sulfur content in rubber by the oxygen cylinder combustion method. This section applies to the determination of total sulfur content in rubber and rubber products other than barium sulfate. The method specified in this part is applicable to the determination of total sulfur content in the following various rubbers: natural rubber, neoprene rubber, styrene-butadiene rubber, butadiene rubber, isoprene rubber, butyl rubber, EPDM rubber, nitrile rubber , hard rubber, and a combination of the above-mentioned rubbers. The methods specified in this standard generally give low results for samples in which lead, antimony, zinc, barium and calcium compounds are present. If the calcium is present in the form of calcium carbonate, reliable test results can be obtained by changing the absorption solution.
