Overview

This European Standard has been prepared by Technical Committee ISO/TC 34 Subcommittee SC 4 "Cereals and pulses" in collaboration with Technical Committee CEN/TC 338 "Cereal and cereal products". This document is a testing standard and it 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. The committee responsible for this standard is Working Committee NA 057-05-06 AA "Getreide und Getreideerzeugnisse" ("Cereal and cereal products") at DIN.
