Samenvatting

< p class=" MsoBodyText" > < span lang=" EN-GB" > Dit document specificeert vier methoden voor de bepaling van het gehalte aan de volgende groepen organische peroxiden die worden gebruikt als rubbervulkaniseermiddelen. Er zijn drie titratiemethoden en één gaschromatografiemethode.< / span>
