This document specifies a method for the determination of the bound acrylonitrile content in NBR by an automatic analyser which uses the Kjeldahl method. The method is also applicable to XNBR (carboxylic acrylonitrile-butadiene rubber) and NBIR (acrylonitrile- butadiene-isoprene rubber) as well as NBR latex.<\/p>\n

NOTE This document and ISO 24698\u20111 can give different results on the same rubber sample.<\/p>\n<\/blockquote>\n
