(1) HCV(%) = Horwitz Coefficients of Variation = 2 (1 -0.5 log (claim %/100))
(2) HSD = Horwitz Standard Deviation = (Claim %) HCV %)/100
(3) "Uniform" samples are homogeneous products which can be analyzed by established procedures. In most cases, validated analytical methods are available for these samples.
(4) "Non-uniform" samples are non-homogeneous samples or products which are difficult to sample or subsample. These products may not be uniformly mixed or packaged and include some special formulations like natural products. These types of samples include fertilizer containing pesticides, pesticides in pressurized containers, strips, plastic bands, collars, grain and other carriers. Natural product formulations such as rotenone and pyrethrin are also included in this group. When it is necessary to use methods which are not validated for accuracy, precision, and reproducibility in a specific matrix, the "non-uniform" guidelines may be used for allowed deviations. The Department may use judgment in placing a sample into the "uniform" or "non-uniform" category.
