WARNING: Personnel using this standard should have practical experience in formal laboratory work. This standard does not address all possible safety issues. It is the user's responsibility to take appropriate safety and health measures and ensure compliance with relevant national regulations. This standard specifies the method for the determination of manganese content in rubber by atomic absorption spectrometry. This standard is applicable to the determination of manganese content in raw rubber, compound rubber and vulcanized rubber with manganese content not less than 0.5mg/kg. For samples with a manganese content lower than 0.5mg/kg, adjust the sample mass or the concentration of the test solution, and it can also be measured, or the standard addition method can be used.
