Organic peroxide subclass 5.2 category C (equivalent to UN Type C)A substance is classified as organic peroxide subclass 5.2 category C 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 C; orii. the substance is an organic peroxide and propagates a detonation as described in UN Test Series Aand does not propagate a detonation under confinement as described in UN Test Series B andpropagates a rapid deflagration as described in UN Test Series C and does not propagate a rapiddeflagration under confinement as described in UN Test Series D and displays violent effect whenheated under confinement as described in UN Test Series E and does not undergo a thermalexplosion when heated under confinement as prescribed in Test Series G; oriii. the substance is an organic peroxide and propagates a detonation as described in UN Test Series Aand does not propagate a detonation under confinement as described in UN Test Series B andpropagates a slow deflagration or propagates no deflagration as described in UN Test Series C anddisplays violent effect when heated under confinement as defined in UN Test Series E and does notundergo a thermal explosion when heated under confinement as prescribed in Test Series G; oriv. the substance is an organic peroxide and propagates a detonation as described in UN Test Series Aand does not propagate a detonation under confinement as described in UN Test Series B andpropagates a rapid deflagration as described in UN Test Series C and does not propagate a rapiddeflagration under confinement as described in UN Test Series D and displays medium effect, loweffect or no effect when heated under confinement as described in UN Test Series E; orv. the substance is an organic peroxide and propagates a detonation as defined in UN Test Series Aand does not propagate a detonation under confinement as described in UN Test Series B andpropagates a slow deflagration or no deflagration as defined in UN Test Series C and displaysmedium effect, low effect or no effect when heated under confinement as described in UN TestSeries E; orvi. the substance is an organic peroxide and propagates a partial detonation as defined in UN Testseries A and propagates a rapid deflagration as defined in UN Test Series C and does not propagatea rapid deflagration under confinement as described in UN Test Series D and displays violent effectwhen heated under confinement as defined in UN Test Series E and does not undergo a thermalexplosion under confinement as described in UN Test Series G; orvii. the substance is an organic peroxide and propagates a partial detonation as defined in UN TestSeries A and propagates a rapid deflagration as defined in UN Test Series C and does notpropagate a rapid deflagration under confinement as defined in UN Test Series D and displaysmedium effect, low effect or no effect when heated under confinement as defined in UN Test SeriesE; orviii. the substance is an organic peroxide and propagates a partial detonation as defined in UN TestSeries A and propagates a slow or no deflagration as defined in UN Test Series C and displaysviolent effect when heated under confinement as described in UN Test Series E and does notundergo a thermal explosion under confinement as described in UN Test Series G; orJanuary 2012 EPA0109
