Rules for classification and labelling of chemicals — Part 2: Explosives
1 Scope
This part of GB 30000 stipulates the terms and definitions, classification, judgment logic and guidance and labelling of explosives.
This part is applicable to the classification and labelling of explosives 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.
GB 13690 General rule for classification and hazard communication of chemicals
The United Nations Recommendations on the Transport of Dangerous Goods: Manual of Tests and Criteria (Rev.5)
The United Nations Recommendations on the Transport of Dangerous Goods: Model Regulations (Rev.17)
The United Nations Globally Harmonized System of Classification and Labelling of Chemicals (Rev.4)
3 Terms and definitions
For the purposes of this document, the terms and definitions given in GB 13690 and the following apply.
3.1
explosive substances (or mixtures)
solid or liquid substance (or its mixture) which can generate gas at a certain speed, temperature and pressure inside through chemical reaction and has destructive effect on the surrounding environment; pyrotechnic substances or mixtures are explosive substances regardless of whether they produce gas or not
3.2
pyrotechnic substances (or mixtures)
substance or mixture which can generate non-detonation and self-oxygen-supplying exothermic chemical reactions, and generate heat, light, sound and gas, smoke or a combination of these several effects
3.3
explosive articles
article containing one or more explosive substances or mixtures thereof
3.4
pyrotechnic articles
article containing one or more pyrotechnic substances or mixtures thereof
3.5
explosives
explosives that include the following three categories:
——explosive substances and mixtures;
——explosives, excluding those devices containing a certain number of explosives or mixtures thereof; when the explosives in these devices are ignited or detonated due to carelessly or unintentionally, the effects such as projection, fire, smoke, heat release or loud noise will not have any effect outside the device;
——substances, mixtures and articles, such as pyrotechnics, which are not mentioned in the above two items, but are actually manufactured to produce explosion or fireworks effects.
4 Classification standards
4.1 Explosives are classified into six categories according to their hazardous characteristics:
a) Item 1.1: substances, mixtures and products with mass explosion hazard in (mass explosion is an explosion that actually instantly ignites almost all contents);
b) Item 1.2: substances mixtures and articles which have a projection hazard but not a mass explosion hazard;
c) Item 1.3: substances mixtures and articles which have a fire hazard and either a minor blast hazard or a minor projection hazard or both, but not a mass explosion hazard;
1) Combustion produces significant radiant heat;
2) Burning one by one, while producing smaller detonation or ejection or both;
d) Item 1.4: substances, mixtures and articles that do not have significant explosion hazards, if ignited or detonated, only have small hazards, and may be controlled in the package to the maximum extent, and the mass and throwing distance of thrown fragments shall not exceed the relevant regulations; external fire will not cause the mass explosion of the contents of the package;
e) Item 1.5: substances or mixtures that have mass explosion hazard but are inherently insensitive. Although they have a mass explosion hazard, they are extremely insensitive, therefore, the possibility of detonation or transition from combustion to detonation under normal conditions is very small;
f) Item 1.6: articles that are extremely insensitive and have no hazard of mass explosion These articles contain only insensitive detonation substances or mixtures and those which have proved to have a near zero probability of accidental initiation.
4.2 According to the relevant provisions of Test Series 2 to Test Series 8 of Part I of the United Nations Recommendations on the Transport of Dangerous Goods: Manual of Tests and Criteria (hereinafter referred to as the Manual of Tests and Criteria), explosives that have not been classified as unstable explosives are classified as one of the above six items according to Table 1:
