Reproducibility (RSD R ) a Concentrations apply to (1) “ready-to-feed” liquids “as is”; (2) reconstituted powders (25 g into 200 mL water); and (3) liquid concentrates diluted 1:1 by weight. b µg/100 g expressed separately as vitamin D 2 and vitamin D 3 in reconstituted final product.
Predicted non-Compliance Rate
Method Reproducibility = 6.4% RSD Measured results on sample with a true value at the mid- results for Stage I Infant Formula will exceed the regulatory limits.
Method Reproducibility = 11.4% RSD Measured results on sample with a true value at the mid- results will exceed the regulatory limits
