DESCRIPTION

BS EN ISO 16634-1:2008

This standard BS EN ISO 16634-1:2008 Food products. Determination of the total nitrogen content by combustion according to the Dumas principle and calculation of the crude protein content is classified in these ICS categories:

65.120 Animal feeding stuffs
67.200.20 Oilseeds
67.050 General methods of tests and analysis for food products

This part of ISO 16634 specifies a method for the determination of the total nitrogen content and the calculation of crude protein content of oilseeds and animal feeding stuffs.

This method, like the Kjeldahl method, does not distinguish between protein nitrogen and non-protein nitrogen. For the calculation of protein content, various conversion factors are used (see Annex D).

This method is not applicable to milk and milk products, for which a method is specified in ISO 14891|IDF 185^[10].
