This standard specifies the quality control requirements for aniline, including its safety information, sampling, test methods, inspection rules, marking, labeling, Encasement, transportation and storage. The molecular formula of aniline is C H NH ², the relative molecular mass is 93.13 (according to the 2011 International Relative Atomic Mass), and the CAS number is 62-53-3. This standard applies to the mass management of aniline during production and application to ensure that it complies with relevant safety and technical specifications. The normative documents involved include Encasement signs for dangerous goods, general rules for sampling chemical products, specifications and test methods for analytical laboratory water, etc., to ensure the safe use of aniline and the effective control of its mass.
