标准摘要
[中文适用范围]： 本标准规定了采用凯氏定氮法自动分析仪测定丁腈橡胶中结合丙烯腈含量的方法。 该方法也适用于XNBR（羧基丙烯腈-丁二烯橡胶）和NBIR（丙烯腈-丁二烯-异戊二烯橡胶）以及NBR乳胶。 注：本文件和 ISO 24698-1 可能对同一橡胶样品给出不同的结果。 [外文原描述]： 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. NOTE This document and ISO 24698‑1 can give different results on the same rubber sample.
