Desensitised explosives

2.17.4.1. |
The classification procedure for desensitised explosives does not apply if:
(a)
The substances or mixtures contain no explosives according to the criteria in Section 2.1; or
(b)
The exothermic decomposition energy is less than 300 J/g. |
|
2.17.4.2. |
The exothermic decomposition energy shall be determined using the explosive already desensitised (i.e.: the homogenous solid or liquids mixture formed by the explosive and the substance(s) used to suppress its explosive properties). The exothermic decomposition energy may be estimated using a suitable calorimetric technique (see Section 20, sub-section 20.3.3.3 in Part II of the UN RTDG, Manual of Tests and Criteria). |
