# Commission Implementing Regulation (EU) 2016/1240 of 18 May 2016 laying down rules for the application of Regulation (EU) No 1308/2013 of the European Parliament and of the Council with regard to public intervention and aid for private storage (Text with EEA relevance), Division 9.2: Calculation of the percentage of rennet whey powder in the sample:

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

W = S III [E] – [1, 3 + (S III [0] – 0,9)]
where:
W the percentage m/m of rennet whey in the sample [E];
S III [E] the relative area of peak III of test sample [E] obtained as in 9.1.2;
1,3 represents the relative average area of peak III expressed in grams of rennet whey per 100 g determined in non-adulterated skimmed milk powder of various origins. This figure was obtained experimentally;
S III [0] represents the relative area of peak III which is equal to R III × A III [0]. These values are obtained in 9.1.1 and 8.5.3 respectively;
(S III [0] – 0,9) represents the correction to be made to the relative average area 1,3 when S III [0] is not equal to 0,9. Experimentally the relative average area of peak III of the control sample [0] is 0,9.
