organic peroxides which have already been classified and are already permitted for carriage in packagings are listed in 2.2.52.4, those already permitted for carriage in ibcs are listed in4.1.4.2, packing instruction ibc520 and those already permitted for carriage in tanks in accordance with chapters 4.2 and 4.3 are listed in4.2.5.2, portable tank instruction t23. each permitted substance listed is assigned to a generic entry of table a of chapter 3.2 (un nos. 3101 to 3120) and appropriate subsidiary hazardsand remarks providing relevant transport information are given.
these generic entries specify:
- the type (b to f) of organic peroxide (see 2.2.52.1.6 above);
- physical state (liquid/solid); and
- temperature control (when required), see 2.2.52.1.15 and 2.2.52.1.16.
mixtures of these formulations may be classified as the same type of organic peroxide as that of the most dangerous component and be carried under the conditions of carriage given for this type. however, as two stable components can form a thermally less stable mixture, the self-accelerating
decomposition temperature (sadt) of the mixture shall be determined and, if necessary, the control and emergency temperatures derived from the sadt in accordance with 7.1.7.3.6.
