| Published By | Publication Date | Number of Pages |
| BSI | 2018 | 18 |
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.
