The computed result is presented as the arithmeticalmean of the results of two independent
determinations acquired under repeat conditions, retain three significant figures.
7 Precisiondegree
Absolute difference of the results of two independent determinations acquired under repeat
conditions should not exceed 10%of the arithmeticmean.

The limit of detection in this standard is 0.04 g/100g*, and the limit of quantitation is 0.2
g/100g*.
*concentrations apply to solid powders, if apply to reconstituted powders(25 g into 200gof
water), the limit of detection is 0.005 g/100g and the limit of quantitation is 0.022
g/100g.
