Warning --- personnel using this standard should have formal laboratory work experience. This standard does not indicate all possible safety issues
question. It is the user's responsibility to take appropriate safety and health measures and to ensure compliance with the requirements of the relevant state laws and regulations.
1 Scope
This standard specifies the oxygen bomb combustion - ion chromatography Determination of thermoplastic elastomers and their products halogen chloride, bromine content of the test
method.
This standard applies to thermoplastic elastomers and their products halogen chlorine, bromine determination, also applies to aqueous samples or difficult to burn
Determination of chlorine and bromine in samples. Determination of chlorine ≤ 1500mg/kg, bromine ≤ 1500mg/kg; method detection limit. Chlorine 15mg/kg,
Bromine 75 mg/kg.
This standard does not apply to the initial sample or in the combustion step to produce insoluble halide samples.
