The sampling procedures described in this practice have been designed to ensure random sampling of finished leather and fabricated leather items for physical and chemical tests. Leather is a natural product and as such is 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.

1.1 This practice covers the sampling of finished leather and fabricated leather items for physical and chemical tests. The product is grouped into lots that are randomly sampled in such a manner as to produce a representative sample of the lot. This sample may be used to determine compliance of the lot with applicable specification requirements, and on the basis of results, the lot may be accepted or rejected in its entirety.

1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
