This standard specifies the technical requirements, test methods, inspection rules, marking, Encasement, transportation and storage of muffle furnace temperature controllers for coal analysis. It is suitable for digital temperature controllers that need to control the muffle furnace heating process in coal analysis. In the cited documents, including industrial analysis methods of coal, batch inspection count sampling procedures, bituminous coal adhesion index and Rogge index determination methods, etc. The performance of the temperature control instrument should meet the relevant requirements, such as the working environmental conditions should be between 0 ° C and 40 ° C, the relative humidity should be between 20% and 90%, and the power supply is (220 +/- 40) V, (50 +/- 1) Hz.
