# Council Decision of 14 November 1992 laying down methods for the analysis and testing of heat-treated milk for direct human consumption (92/608/EEC), Division 8.1: Calculation and formula:

Extent: E+W+S+N.I.

Calculate the nitrogen content (WN), expressed in grams of nitrogen per 100 g of product by:
W N = 1,40 V - V 0 c m
where:
WN the nitrogen content.
V the volume in millilitres of the standard volumetric solution of acid used in the determination.
Vo the volume in millilitres of the standard volumetric solution of acid used in the blank test,
c the concentration, expressed as moles per litre of the acid standard volumetric solution (4.7.).
m the mass in grams of the test portion.
Round off the result to the nearest 0,001 g per 100 g.
