1 Scope
This part of GB 30000 specifies the terms and definitions, classification, judgment logic and guidance and labelling of organic peroxides.
This part is applicable to the classification and labelling of organic peroxides according to the United Nations Globally Harmonized System of Classification and Labelling of Chemicals (GHS).
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

3 Term and definition
For the purposes of this document, the terms and definitions given in GB 13690 and the following apply.
3.1
organic peroxides
liquid or solid organic matter containing divalent -O-O- structure and derivatives of hydrogen peroxide whose one or two hydrogen atoms have been replaced by organic groups
This term also includes organic peroxide preparations (mixtures). Organic peroxides are thermally unstable substances or mixtures which may undergo exothermic self-accelerating decomposition. In addition, they may have one or more of the following properties:
a) easily exploded and decomposed;
b) burning quickly;
c) sensitive to impact or friction;
d) hazardous reaction with other substances.
If its preparation easily explodes or deflagrates rapidly in laboratory tests, or shows severe effects when heated under closed conditions, it is considered that the organic peroxide has explosive properties.
