dangerous goods - General specifications
1 Scope
This standard specifies the terms and definitions, classification, requirements, testing,
marking, inspection rules of dangerous goods.
This standard is applicable to the inspection of dangerous characteristics of dangerous
goods.
2 Normative references
The provisions in following documents become the provisions of this Standard through
reference in this Standard. For the dated references, the subsequent amendments
(excluding corrections) or revisions do not apply to this Standard; however, parties who
reach an agreement based on this Standard are encouraged to study if the latest versions
of these documents are applicable. For undated references, the latest edition of the
referenced document applies.
GB 190 Packing symbol of dangerous goods
GB/T 3690-1992 Classification and sign of commonly used dangerous chemical
products
United Nations Recommendations on the Transport of Dangerous Goods - Model
Regulations (13th revision)
3 Terms and definitions
The following terms and definitions, which are defined in GB/T 3690 and
"Recommendations on the Transport of Dangerous Goods - Model Regulations" (13th
revision) apply to this standard.
3.1
Explosive
Solid or liquid substances which, under external action (such as heat, pressure,
impact, etc.), can undergo violent chemical reactions, generate a large amount of gas
and heat instantaneously, cause the surrounding pressure to rise rapidly and explode,
thereby damaging the surrounding environment items. It also includes items, which
have no mass explosion hazard, as well as the items with combustion, projectile,
minor explosion hazards.
3.2
Gas
Substances which have a vapor pressure greater than 300 kPa at 50 °C. OR a
substance that is completely gaseous at a standard pressure of 101.3 kPa at a
temperature including 20 °C. It includes compressed gases, liquefied gases,
dissolved gases, refrigerated liquefied gases, gas mixtures, mixtures of one or more
gases with vapors of one or more other categories of substances, gas-filled articles
and aerosols.
3.3
Flammable liquid
Flammable liquids, liquid mixtures or liquids containing solid substances. It
excludes liquids which are included in other categories because of their hazardous
properties. Its closed cup test flash point is equal to or lower than 61 °C.
3.4
Flammable solid, spontaneously combustible, contact water emit flammable
gases
Flammable solids refer to solids, which have low ignition point, are sensitive to heat,
impact, friction, are easy to be ignited by external fire sources and burn rapidly,
meanwhile emit toxic smoke or gas. It does not include items listed as explosives.
Spontaneously combustible substances refer to substances, that have a low
spontaneous ignition point AND are prone to oxidation reactions in the air, releasing
heat and burning by themselves.
Substances that emit flammable gases when in contact with water refer to substances,
that are liable to become spontaneously combustible or emit dangerous quantities of
flammable gases, when exposed to water.
3.5
Oxidizer, organic peroxide
Oxidizers refer to substances that do not necessarily combust themselves, BUT
usually cause or promote the combustion of other substances, by releasing oxygen.
Organic peroxides refer to organic substances, which contain peroxide-groups in
- Item 1.2: Substances and articles which present a projection hazard but not a mass
explosion hazard;
- Item 1.3: Substances and articles which have a fire hazard and a local explosion
hazard or a local projection hazard or both, BUT which do not have a mass
explosion hazard;
- Item 1.4: Substances and articles which do not present a significant hazard;
- Item 1.5: Substances which are very insensitive BUT have mass explosion hazard;
- Item 1.6: Substances which are extremely insensitive BUT have no mass explosion
hazard.
4.1.3 Category 2: Gases
- Item 2.1: Flammable gases;
- Item 2.2: Non-flammable non-toxic gas;
- Item 2.3: Toxic gases.
4.1.4 Category 3: Flammable liquids
4.1.5 Category 4: Flammable solids; spontaneously combustible; contact water emit
flammable gases
- Item 4.1: Flammable solids, self-reactive substances, desensitized explosives;
- Item 4.2: Substances liable to spontaneous combustion;
- Item 4.3: Substances which, in contact with water, emit flammable gases.
4.1.6 Category 5: Oxidizers and organic peroxides
- Item 5.1: Oxidizers;
- Item 5.2: Organic peroxides.
4.1.7 Category 6: Toxic and infectious substances
- Item 6.1: Toxic substances;
- Item 6.2: Infectious substances.
4.1.8 Category 7: Radioactive substances
4.1.9 Category 8: Corrosive substances
4.1.10 Category 9: Miscellaneous dangerous substances and articles
4.2 Category of dangerous goods packaging
Except for the dangerous goods of category 1, category 2, category 7, items 5.2 and 6.2,
the packaging of other types of dangerous goods can be divided into three packing
levels, according to the degree of danger, namely:
Packing group I - Highly hazardous substances;
Packing group II - Substances of moderate danger;
Packing group III - Substances of minor danger;
The division of the degree of danger of various dangerous goods can be determined
through tests related to hazardous characteristics.
5 Requirements
5.1 Safety requirements
5.1.1 The producer of a new product or the entrusting party applying for the
classification of the product shall provide all available safety data about the product,
such as toxicity data.
5.1.2 When there is suspicion of explosiveness, a small-scale preliminary test shall be
carried out first; then the test of a larger quantity of substances shall be carried out.
Preliminary tests include determining the sensitivity of the substance to mechanical
stimuli (impact and friction) as well as to heat and flame.
5.1.3 In tests involving the initiation of potentially explosive substances or articles, a
safe waiting period shall be maintained after initiation.
5.1.4 Extra care shall be taken in handling the tested samples; the tested samples shall
be destroyed, as soon as possible after the test.
5.2 Test requirements
5.2.1 The test of hazardous characteristics shall be carried out, according to the test
conditions. If no tolerance is given in the experiments, this means that the accuracy is
determined by the number of decimal places for any given dimension, e.g., 1.1 means
1.05 to 1.15. If the conditions during the test deviate from the given conditions, the
reason for the deviation shall be stated in the test report.
