GB 5085.1-2007Identification standards for hazardous wastes - (English PDF)

Foreword

In order to implement The Law of the People's Republic of China on Environmental Protection and The Law of the People's 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.

1 Scope

This Standard stipulates the identification standards for corrosive hazardous wastes.

This Standard is applicable to the identification for corrosivity of any solid wastes that are generated in production, life and other activities.
