- Scope
- This part of SH/T 1157 specifies two methods for determining the combined acrylonitrile content in acrylonitrile-butadiene rubber (NBR) using the Kjeldahl method: Method A and Method B. This section is applicable to the determination of NBR raw rubber, and other NBR can also be used with reference. These two methods may produce different results, and in case of dispute, Method A should be used.
