Standard Practice for Sampling and Preparation of Wet Blue and Wet White for Physical and Chemical Tests

Importancia y uso:

4.1 The sampling procedures described in this practice have been designed to ensure random sampling of Wet Blue and Wet White for physical and chemical tests. Wet Blue and Wet White are natural products and as such are subject to extensive variability. The physical and chemical properties vary considerably depending on location on the hide, side, or skin from which the test sample is taken. Random sampling of specimens from a predefined location and orientation minimizes test bias and variability. This practice defines these parameters.
