Description / Abstract:

This International Standard 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 1 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 nitrogencontaining constituents are also present. however, and in the dry solids prepared from natural rubber latex these materials can make a substantial contribution to the total nitrogen content.
