DESCRIPTION
BS ISO 1656:2019
This standard BS ISO 1656:2019 Rubber, raw natural, and rubber latex, natural. Determination of nitrogen content is classified in these ICS categories:
- 83.040.10 Latex and raw rubber
This document specifies a macro-method and a semi-micro method for the determination of nitrogen in raw natural rubber and in natural rubber latex using variants of the Kjeldahl process.
NOTE
The determination of nitrogen in natural rubber is usually carried out in order to arrive at an estimate of the protein content. Minor amounts of non-proteinous nitrogen containing constituents are also present. However, in the dry solids prepared from natural rubber latex, these materials can make a substantial contribution to the total nitrogen content.
