Announcement of State Administration for Environmental
Protection
Year-2007 No. 37
In order to implement The Law of the PEOPLE Republic of China on Environmental Protection and The Law of the PEOPLE Republic of China on the Prevention and Control of Environmental Pollution by Solid Waste, protect the environment and protect human health, seven standards, including Identification Standards for Hazardous Wastes - General Specification, are hereby approved to be national technical standards on solid waste pollution and environmental control, which are jointly issued by General Administration of Quality Supervision, Inspection and Quarantine, and our administration.
The title and serial No. of the standards are as follows:
1. Identification Standards for Hazardous Wastes - General Specification (GB 5085.7-2007)
2. Identification Standards for Hazardous Wastes - Identification for Corrosivity (GB 5085.1-2007)
3. Identification Standards for Hazardous Wastes - Screening Test for Acute Toxicity (GB 5085.2-2007)
4. Identification Standards for Hazardous Wastes - Identification for Extraction Toxicity (GB 5085.3-2007)
5. Identification Standards for Hazardous Wastes - Identification for Ignitability (GB 5085.4-2007)
6. Identification Standards for Hazardous Wastes - Identification for Reactivity (GB 5085.5-2007)
7. Identification Standards for Hazardous Wastes - Identification for Toxic Substance Content (GB 5085.6-2007)
In accordance with relevant provisions by law, the above standards have the effectiveness of enforcement.
The above standards, which shall be put into effect since October 1, 2007, are published by China Environmental Science Press. The content of the standards may be inquired through the website of the State Administration for Environmental Protection (website: www.sepa.gov.cn/tech/hjbz/bzwb).
Foreword
In order to implement The Law of the PEOPLE Republic of China on Environmental Protection and The Law of the PEOPLE Republic of China on the Prevention and Control of Environmental Pollution by Solid Waste, prevent and control environmental pollution caused by hazardous wastes, reinforce the management of hazardous wastes, protect the environment and protect human health, this Standard is formulated. This Standard is a constituent part of the national identification standards for hazardous wastes. The national identification standards for hazardous wastes stipulate the technical indicators of hazardous characteristics of solid wastes. Solid wastes whose hazardous characteristics comply with the technical indicators stipulated in this Standard belong to hazardous wastes and shall be managed as hazardous wastes pursuant to law. The national identification standards for hazardous wastes are constituted of the following seven standards:
1. Identification Standards for Hazardous Wastes - General Specification 2. Identification Standards for Hazardous Wastes - Identification for Corrosivity 3. Identification Standards for Hazardous Wastes - Screening Test for Acute Toxicity
4. Identification Standards for Hazardous Wastes - Identification for Extraction Toxicity
5. Identification Standards for Hazardous Wastes - Identification for Ignitability 6. Identification Standards for Hazardous Wastes - Identification for Reactivity 7. Identification Standards for Hazardous Wastes - Identification for Toxic Substance Content
This Standard is an amendment of Identification Standard for Hazardous Wastes - Identification for Corrosivity (GB 5085.1-1996). The main content adds identification standard and test method for steel corrosion.
In accordance with relevant provisions by law, this standard has the effectiveness of enforcement.
This Standard was proposed by the Science and Technology Standard Office of State Administration for Environmental Protection.
The drafting organizations of this Standard: Solid Waste Pollution Control Technology Research Institute of Chinese Research Academy of Environmental Sciences; Environmental Standard Research Institute of Chinese Research Academy of Environmental Sciences.
