This International Standard specifies four methods for the determination of the content of the following groups of organic peroxides used as rubber vulcanizing agents. There are three titration methods and one using capillary gas-chromatography.1.1 Titration method A for group a) peroxyketals— DTBPC: 1,1-Di(tert-butylperoxy)cyclohexane;— DBPMC: 1,1-Di(tert-butylperoxy)-2-methylcyclohexane;— DBPTC: 1,1-Di(tert-butylperoxy)-3,3,5-trimethylcylcohexane;— DBPB: 2,2-Di(tert-butylperoxy)butane;— BPV: Butyl -4,4-di(tert-butylperoxy)valerate.1.2 Titration method B for group b) diacyl peroxides— Dibenzoyl peroxide;— Di(2,4-dichlorobenzoyl) peroxide;— Di(4-methylbenzoyl) peroxide.1.3 Titration method C for group c) diaralkyl and alkyl-aralkyl peroxides— Di(tert-butylperoxyisopropyl)benzene;— Dicumyl peroxide;— tert-Butyl cumyl peroxide.1.4 Capillary gas-chromatography for dialkyl peroxides— 2,5-Dimethyl-2,5-di(tert-butylperoxy)hexane.
