scope:
This part of ISO 16634 specifies a method for the determinatio n of the total nitrogen content and the calculation of crude p rotein content of oilseeds and animal feeding stuffs. This met hod, like the Kjeldahl method, does not distinguish between pr otein nitrogen and non-protein nitrogen. For the calculation o f protein content, various conversion factors are used (see An nex D).
