Cereals and pulses -- Determination of the nitrogen content and calculation of the crude protein content -- Kjeldahl method

This standard has been revised by: ISO 20483:2013


ISO 20483:2006 specifies a method for the determination of the nitrogen content of cereals, pulses and derived products, according to the Kjeldahl method, and a method for calculating the crude protein content.

The method does not distinguish between protein nitrogen and non-protein nitrogen. If it is important to determine the non-protein nitrogen content, an appropriate method can be applied.
