"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.

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.
3.3
Flammable liquid
Flammable liquids, liquid mixtures or liquids containing solid substances.
4 Categories
4.1 Category of dangerous goods

4.1.3 Category 2.Gases
4.1.4 Category 3.Flammable liquids

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.
5.2 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.
5.2.2 The composition of the experimental sample shall be consistent with the
concentration of the substance to be transported.
5.2.3 All test materials, in contact with the test substance, shall not affect the test results.
If the effect cannot be ruled out, precautions shall be taken, to prevent it from affecting
the experimental results. The precautionary measures taken shall be listed in the test
