Organic peroxide subclass 5.2 category D (equivalent to UN Type D)A substance is classified as organic peroxide subclass 5.2 category D if:i. the substance is listed in the UN Model Regulations as having a classification or division of anorganic peroxide (classification division 5.2) and is designated as Type D; orii. the substance is an organic peroxide and propagates a partial detonation as described in UN TestSeries A and propagates a slow deflagration or no deflagration as defined in UN Test Series C anddisplays medium effect, low effect or no effect when heated under confinement as defined UN TestSeries E; oriii. the substance is an organic peroxide and does not propagate a detonation as defined in UN TestSeries A and propagates a slow deflagration as defined in UN Test Series C and displays mediumeffect, low effect or no effect when heated under confinement as defined in UN Test Series E; oriv. the substance is an organic peroxide and does not propagate a detonation as defined in UN TestSeries A and does not propagate a deflagration as defined in UN Test Series C and displays mediumeffect when heated under confinement as defined in UN Test Series E.These classification criteria are summarised in Table 7.6.
