Popis

BS EN ISO 20483:2013


This standard BS EN ISO 20483:2013 Cereals and pulses. Determination of the nitrogen content and calculation of the crude protein content. Kjeldahl method is classified in these ICS categories:
  • 67.060 Cereals, pulses and derived products

This International Standard 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 would be applied.

NOTE In certain cases, full recovery of the nitrogen in nitrates and nitrites is not possible by this method.
