Is there any standard that provides an accurate definition of combustible liquids and flammable liquids?
According to GB20581, materials with a value between 60 and 93 are combustible, while those with a value below 60 are flammable
Basic classification of flammable and combustible liquids SYT6460-2000: Combustible liquid refers to a liquid whose closed-cup flash point is equal to or higher than 37.8°C. Flammable liquid refers to a liquid whose flash point in a closed cup is below 37.8°C, and whose vapor pressure at 37.8°C does not exceed 275 kPa (40 psia) (according to GB/T8017)
SYT6460-2000 is a petroleum standard, while GB20581 is a **standard
GB20581-2006 \"Safety specifications for the classification, hazard labeling and safety data sheets of chemicals – Flammable liquids\" defines flammable liquids as liquids with a flash point of 93°C or less, which are divided into 4 categories. There is no definition for flammable liquids

The standard GB 20581-2006 \"Safety specifications for the classification, hazard labeling, and safety data sheets of chemicals – Flammable liquids\" has been repealed; the current standard is GB 30000.7-2013 \"Specifications for the classification and labeling of chemicals – Part 7: Flammable liquids\". In both standards, flammable liquids refer to those with a flash point of 93°C or less, whereas according to the labeling requirements, liquids with a flash point above 60°C are considered combustible liquids.
The owner mentioned that there is a **document requiring that facilities handling flammable liquids be reported to the fire department; in such cases, the definition of flammable liquids becomes very important.
According to GB50074, a flash point below 45 degrees indicates flammability, while a flash point equal to or above 45 degrees indicates combustibility
Different standards define things differently; what should be done in this case?
