Alcohol-based liquid fuel
Dangers—Alcohol-based liquid fuels are classified as Class 2 flammable liquids. Methanol has a Class 3 acute oral toxicity, a Class 3 acute skin toxicity, a Class 3 acute inhalation toxicity, and a Class 1 specific target organ system (eyes, central nervous system) toxicity. If appropriate precautions are not taken, the products covered in this
document may present hazards during production, storage, transportation, and use. This document does not purport to address all safety concerns related to this product.
Operators and users are responsible for implementing appropriate personal safety and health measures and ensuring compliance with relevant national laws and regulations.
1 Scope
This document specifies the product varieties, marking, requirements and testing of alcohol-based liquid fuels with methanol as the main component and water and blue colorant added.
Methods, inspection rules, marking and accompanying documents, packaging, storage, road transportation and safety. This
document applies to civilian alcohol-based liquid fuels used in burning appliances, and industrial alcohol-based liquid fuels are subject to the same regulations.

3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
Combustion appliances are appliances that use
gaseous or liquid fuels as energy and utilize the principle of combustion to generate heat for cooking, heating, hot water supply, etc.
4 Product Varieties and Labeling
4.1 Product Variety
Alcohol-based liquid fuels include civilian alcohol-based liquid fuels and industrial alcohol-based liquid fuels. Civilian alcohol-based liquid fuels are blue liquid fuels made primarily of methanol, with water and colorants added. They are supplied to residential and commercial (public building) appliances. Industrial alcohol-based liquid fuels are a mixture of alcohols,
hydrocarbons, and water, and are supplied to industrial enterprises for use as fuel. Civilian alcohol-based liquid fuels are categorized
into three grades based on their methanol content: AF-80, AF-90, and AF-95. AF-80 alcohol-based liquid fuel is suitable for applications where calorific value is not a high priority, such as slow cooking. AF-90 alcohol-based liquid fuel can be used in most kitchen cookware.
AF-95 alcohol-based liquid fuel can be used in boilers of non-special equipment and household water heaters, etc.
4.2 Product Marking
Alcohol-based liquid fuel products are marked as: variety code product name.
Example: An alcohol-based liquid fuel product with a methanol content (mass fraction) of 90% is labeled as:
AF-90 alcohol-based liquid fuel.
5 Requirements and test methods
5.1 The technical requirements and test methods for alcohol-based liquid fuels shall comply with the provisions of Table 1.
5.2 The water used for alcohol-based liquid fuel shall meet the requirements of GB5749, and the raw material methanol shall meet the following requirements:
