Foreword

In order Environmental pollution caused by hazardous wastes, strengthening the management of hazardous wastes, protecting the environment, and protecting human health, setting the standard. This standard is part of the national hazardous waste identification standard. The national hazardous waste identification standard specifies the hazardous characteristics of solid waste Technical indicators, hazardous properties The solid wastes that meet the technical specifications specified in the standards are hazardous wastes and must be piped according to the law. Reason. The national hazardous waste identification standard consists of the following seven criteria. 1. General rules for the identification of hazardous wastes 2. Corrosion identification of hazardous waste identification standards 3. Identification criteria for hazardous wastes Acute toxicity screening 4. Identification of leaching toxicity of hazardous waste identification standards 5. Identification of flammability of hazardous waste identification standards 6. Reactive identification of hazardous waste identification standards 7. Identification of hazardous substances for identification of toxic substances This standard is a new part. According to relevant laws, this standard has the effect of enforcement. This standard was proposed by the Science and Technology Standards Division of the State Environmental Protection Administration. This standard was drafted by the Chinese Academy of Environmental Sciences Institute of Environmental Standards and Solid Waste Pollution Control Technology Institute. This standard was approved by the State Environmental Protection Administration on March 27,.2007. This standard has been implemented since October 1,.2007. This standard is interpreted by the State Environmental Protection Administration. GB 5085.4.2007 Identification of flammability of hazardous waste identification standards

1 Scope

This standard specifies the criteria for the identification of flammable hazardous wastes. This standard applies to the identification of the flammability of solid waste produced in any production, life and other activities.

2 Normative references

The clauses in the following documents are quoted in this part of GB 5085 as the clauses of this standard. Any undated quoted text The latest version is applicable to this standard. GB/T 261 flash point determination of petroleum products (closed cup method) GB 19521.1 Safety Code for Inspection of Hazardous Characteristics of Combustible Solid Dangerous Goods GB 19521.3 Safety Code for Inspection of Hazardous Characteristics of Flammable Gas Dangerous Goods HJ/T 298 Technical Specifications for Identification of Hazardous Wastes

3 Terms and Definitions

The following terms and definitions apply to this standard. 3.1 Flash point flash point It means that under the standard atmospheric pressure (101.3 kPa), the flammable vapor released above the liquid surface is completely mixed with air and can be The minimum temperature at which a flame or spark ignites. 3.2 Lower flammable limit The minimum concentration of combustible gases or mixtures of steam and air (or oxygen) that can spread the flame after ignition, in % Show. 3.3 Upper flammable limit The highest concentration of combustible gases or mixtures of vapor and air (or oxygen) that can spread the flame after ignition, in % Show. 3.4 Flammable range A combustible gas or mixture of vapor and air (or oxygen) can ignite and propagate a range of flame concentrations, usually flammable The volume fraction of gas or vapor in the mixture.

4 Identification criteria

Solid wastes that meet any of the following conditions are flammable hazardous wastes. 4.1 Liquid Flammable Hazardous Waste Liquids, liquid mixtures, or solids containing liquids with a flash point below 60 °C (closed cup test). 4.2 Solid flammable hazardous waste Fires due to friction or spontaneous combustion at standard temperature and pressure (25 °C, 101.3 kPa), can be intense and persistent after ignition GB 5085.4.2007 Burns and produces hazardous solid waste. 4.3 gaseous flammable hazardous waste At 20 °C, 101.3 kPa, in a mixture with air, ignitable gas with volume fraction ≤ 13%, or in The difference between the flammable limit and the flammable limit of the flammable range is greater than or equal to 12 percentage points regardless of the lower flammable limit, regardless of the lower flammable limit. Point of gas.

5 experimental methods

5.1 Sampling points and sampling methods are performed in accordance with the provisions of HJ/T 298. 5.2 Article 4.1 shall be conducted in accordance with the provisions of GB/T 261. 5.3 Article 4.2 shall be conducted in accordance with the provisions of GB 19521.1. 5.4 Article 4.3 shall be conducted in accordance with the provisions of GB 19521.3.
