GB13690 defines and the following terms and definitions apply to this document 3.1|| tt||Explosive substances (or mixtures) A solid or liquid substance (or mixture) that can generate gas at a certain speed, temperature and pressure through chemical reactions and has a destructive effect on the surrounding environment. Pyrotechnic substances or mixtures are explosive substances regardless of whether they generate gas or not. 3.2
Pyrotechnic substances (or mixtures) Substances or mixtures that can undergo non-detonation and self-oxygen exothermic chemical reactions mixture and produces heat, light, sound, gas, smoke or a combination of these effects. 3.3

Pyrotechnic articles
Articles containing one or more pyrotechnic substances or their mixtures. 3.5
Explosives
Explosives include the following three categories:
explosive substances and mixtures;
|Explosives do not include devices containing a certain amount of explosives or their mixtures, where the explosives in these devices, when accidentally or unintentionally ignited or detonated, produce effects such as projection, fire, smoke, heat release or loud noise, which will not produce any effects outside the device:
GB30000.2—2013
Substances, mixtures and articles that are not mentioned in the above two items, but are actually manufactured to produce explosion or fireworks effects, such as pyrotechnic products.
4 Classification standards
4.1 According to the dangerous characteristics of explosives, they are divided into six categories:8) 1.1) Substances, mixtures and articles with a mass explosion hazard (a mass explosion is an explosion that actually instantly ignites almost all of the contents);
b) 1.2) Substances, mixtures and articles with a projection hazard but no mass explosion hazard; with a combustion hazard and a smaller detonation hazard or a smaller projection hazard or both, but no mass explosion hazard c) 1.3) Substances, mixtures and articles with a mass explosion hazard:
1) Burning produces significant radiant heat;
Burning one after another, with a smaller detonation or projection effect or both; 2
d) 1.4) No significant explosion hazard Substances, mixtures and articles, if ignited or detonated, only pose a small risk and can be controlled to the maximum extent in the package, and the mass and projection distance of the thrown fragments do not exceed the relevant regulations; external fire will not cause the contents of the package to explode as a whole; e) 1.5 items have an overall explosion hazard, but are very insensitive substances or mixtures. Although they have an overall explosion hazard, they are extremely insensitive, so that the possibility of detonation or conversion from combustion to detonation under normal conditions is very small; 16 items of extremely insensitive articles with no overall explosion hazard, these articles only contain extremely insensitive detonation substances or mixtures and those articles that have been proven to have almost zero possibility of accidental detonation. 4.2 According to the relevant provisions of Test Series 2 to Test Series 8 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 are not classified as unstable explosives are classified into one of the above six categories according to Table 1:
Table 1 Explosive Standards
Unstable Explosives
Or Explosives of Divisions 1.1 to 1.6
For explosives of Divisions 1.1 to 1.6, the following set of core tests are required: Explosiveness: According to Test Series 2 (Section 12 of the "Manual of Tests and Criteria", the intended explosives do not need to be subjected to Test Series 2. Sensitivity: According to Test Series 3 (Section 13 of the "Manual of Tests and Criteria". Thermal stability: According to Test Series 3 (c) (Section 13.6.1 of the "Manual of Tests and Criteria". For correct classification, further tests are required in addition to the core tests. Unstable explosives are explosives that are thermally unstable and/or too sensitive during normal handling and use. Special care should be taken. Predetermined explosives are substances, mixtures and articles intended to produce actual explosions or pyrotechnic effects. 4.2.1 Explosives or their mixtures and articles in outer packaging can be classified into 1.1 to 1.6. For different purposes, they can be further divided into Compatibility Groups A to S to distinguish their different technical requirements. See Section 2.1 of the United Nations Recommendations on the Transport of Dangerous Goods (hereinafter referred to as the "Model Regulations"). 4.2.2 For some explosives and mixtures that have been moistened with water or ethanol or diluted with other substances in order to suppress their explosive properties, they can be treated differently from explosives and their mixtures for certain purposes (such as transportation) (can be treated as desensitized explosives). 4.2.3 For the classification test of solid substances and mixtures, the test should be carried out according to the substance or mixture provided. If the physical form of the same chemical during its supply or transport is different from that during the test and this difference may substantially change the results of its classification test, the new form of the substance or mixture should be tested. 2
5 Decision logic and guidance
GB30000.2—2013
Decision logic and guidance are provided for reference. See Appendix A for decision logic and guidance. It is particularly recommended that the person responsible for classification study Chapter 4 before and during the use of decision logic.
6 Labeling
6.1 Overview
6.1.1 For the label of explosives, the hazard categories are listed in the order of the designated pictogram, signal word and hazard statement. The hazard classes or categories covered by the Model Regulations should be listed in the label with the designated corresponding graphic symbol for each category. The allocation of label elements for explosives is shown in Appendix B.
6.1.2 See Appendix C for the classification criteria and label elements for explosives. 6.1.3 The information required on the label includes hazard pictograms, signal words, hazard statements, precautionary statements, product identifiers and supplier identification. Note: For other label elements that have not been standardized, such as precautionary statements, they also need to be included on the label. The competent authority may also require additional information, and the supplier may also add supplementary information
6.2 Hazard pictograms
Hazard pictograms should use black symbols with a white background, and the red frame should be wide enough to be eye-catching. The colors, numbers and minimum sizes of hazard pictograms and graphic symbols specified in the Model Regulations are shown in Appendix B. 6.3 Signal words
Signal words are words used on labels to indicate the relative severity of hazards and to alert readers to potential hazards. For unstable explosives, explosives in items 1.1, 1.2, 1.3, and 1.5, the signal word "Danger" is used. For explosives in item 1.4, the signal word "Warning" is used. For explosives, Division 1.6, signal words are not used. 6.4 Hazard Statements
A hazard statement is a phrase assigned to a hazard class and division that describes the hazardous properties of a dangerous product and, where appropriate, its degree of hazard. The hazard statements assigned to the different hazard classes of explosives are given in Table C.1 in Annex C. See also Annex D. 6.5 Precautionary Statements
A precautionary statement is a word (and/or pictogram) describing the recommended measures to minimize or prevent adverse effects resulting from exposure to the dangerous product or from improper storage or handling of the dangerous product. For the purposes of this document, there are five types of precautionary statements: general, precautionary, emergency, storage and disposal. See Annex D for their use. 6.6 Product Identifiers
6.6.1 The product identifier should be used on the label and should be consistent with the product identifier used on the safety data sheet. If a substance or mixture is subject to the Model Regulations, the correct UN shipping name should also be used on the packaging. 6.6.2 The label should include the chemical name of the substance. For mixtures or alloys, when acute toxicity, skin or respiratory sensitization or specific target organ toxicity appear on the label, the label shall include the chemical composition of all ingredients or alloying elements that may cause these hazards. The competent authority may require that the chemical names of all ingredients or alloying elements that may cause the hazard of the mixture or alloy be listed on the label. 3

Decision logic and guidance
GB30000.2—2013
The classification and further classification of explosives is a complex procedure, including three steps (Part I of the Manual of Tests and Criteria): The first step is to confirm whether the substance is explosive, using the test series 5 to test series 4. The third step is to determine the hazard classification, using the test series 2 to test series 4; the third step is to determine whether the "explosive intermediate ammonium nitrate emulsion, suspension or gel (ANE)" is not sensitive enough through test series 8: it can be classified as an oxidizing liquid (Section 213) or an oxidizing solid (Section 2.14). The classification procedure can be carried out according to the following decision logic (see Figures A.1 to A.4). Substances, mixtures or articles to be classified (may be assigned to hazard categories 1.1, 1.21.3, 1.4, 1.5 or 1.6, excluded by the classifier, explosives, compatibility group assignment, compatibility groups A, B, C, D, E, FGHJKL, N, Figure A, 1 Explosives (Class 1 in transport) Classification of substances, mixtures or articles General diagram of procedure TTKAONTCA-

A.2.1 Explosions are caused by the presence of certain chemical groups in the molecule which can react to cause a sudden increase in temperature or pressure. The purpose of the partition test is to identify the potential hazard presented by such reactive groups and the rapid release of energy they cause. If the partition test identifies the substance or mixture as potentially explosive, an approval procedure should be carried out, see Section 10.3 of the Manual of Tests and Criteria. NOTE: If the energy released by decomposition of the organic substance is less than 800 J per gram, then neither the series 1 (a) type detonation diffusion test nor the series 2 (a) type detonation impact sensitivity test need to be carried out. If the energy released by decomposition of the organic substance or its mixture is not less than 800 J per gram, if the detonation sensitivity test is carried out according to No. 8 If the result of the ballistic white cannon Mk.IId test (F.1) or the ballistic white cannon test (F.2) or the BAM Trauser test (F.3) triggered by a detonator (see Appendix ID of the Manual of Tests and Criteria) is none, then tests 1(a) and 2(a) are not required.
