Compared with SN/T1828.13-2006, the main technical changes are as follows: the definition of flammable liquids has been modified (see 3.1, 3.1 of the 2006 edition); the determination of hazard categories has been modified (see 5.1, 5.1 of the 2006 edition); the closed cup flash point and viscosity test results have been modified (see 5.2.2 Table 2, 5.2.2 Table 2 of the 2006 edition): - Added that viscous substances with the following properties should be included in the Class III packaging (see 5.2.4): Added that if the flash point is between 23℃ and 60℃ and meets the following conditions, it can be classified as a non-flammable liquid (see 5.2.5). This part adopts the United Nations "Recommendations on the Transport of Dangerous Goods Model Regulations" (17th revised edition), and its relevant technical content is completely consistent with the above regulations.
This part is proposed and managed by the Certification and Accreditation Administration of the People's Republic of China. This part was drafted by: Tianjin Entry-Exit Inspection and Quarantine Bureau of the People's Republic of China, Hubei Entry-Exit Inspection and Quarantine Bureau of the People's Republic of China.

5.1 Determination of hazard category
Liquids or liquid mixtures with a flash point equal to or lower than 60°C determined by the closed cup flash point test belong to Class 3 flammable liquids. However, if the flash point is higher than 35°C, liquids that do not continue to burn do not belong to Class 3 flammable liquids. 2
