Examples of groups which may indicate explosive properties are given in Table A6.1 in Appendix 6 of the UN RTDG, Manual of Tests and Criteria; or\n(b) The substance contains chemical groups associated with explosive properties which include oxygen and the calculated oxygen balance is less than - 200;\nThe oxygen balance is calculated for the chemical reaction:\nCxHyOz+ [x+ (y/4)-(z/2)] O2 → x CO2 + (y/2) H2O\nUsing the formula:\nOxygen balance = -1 600 [2x + (y/2)-z]/molecular weight;\n(c) For an organic substance, or a homogenous mixture of organic substances, containing a chemical group (or groups) associated with explosive properties:\nthe exothermic decomposition energy is less than 500 J/g, or\nthe onset of exothermic decomposition is 500 °C or above\nas indicated in Table 2.1.3.\nTable 2.1.3\nDecision to apply the acceptance procedure for the hazard class ‘ Explosives ’ for an organic substance or a homogenous mixture of organic substances\nDecomposition energy (J/g)\nDecomposition onset temperature (°C)\nApply acceptance procedure?
