Scope

Scope: This standard specifies the methods for identifying the material of natural leather using sensory methods, comparison with physical samples, and microscopy, including the summary of the methods, equipment, identification procedures, general identification process, identification results, and result reports. This standard applies to the identification of the material of common natural leathers such as cowhide, buffalo hide, mountain sheepskin, and pigskin. Main technical content: Annex A (informative annex) lists the sensory characteristics of common natural leathers by type: 1. Cowhide: Has a full and elastic texture. The grain surface is fine, with compact and visible pores. When lightly scraping the cross-section with a fingernail, the surface color can be divided into two layers: the upper layer is lighter in color with finer scraped fibers; the lower layer is darker in color with thicker scraped fibers. 2. Buffalo hide: Has a full and elastic texture. The pores are sparse and visible, and the grain pattern is rough. When lightly scraping the cross-section with a fingernail, the surface color can be divided into two layers: the upper layer is lighter in color with finer scraped fibers; the lower layer is darker in color with thicker scraped fibers. 3. Goatskin: Has a soft texture. The grain surface is rough. The pores are arranged regularly in depressions, and the nubs are arranged in a shingle-like pattern (or fish-scale pattern). When lightly scraping the cross-section with a fingernail, the surface color can be divided into two layers: the upper layer is lighter in color with finer scraped fibers; the lower layer is darker in color with thicker scraped fibers. It is difficult to tear the skin board with bare hands. 4. Sheepskin: Has a softer texture. The grain surface is fine, with nearly circular pores of uniform size, arranged randomly or in clusters and rows. The grain surface is divided into countless large or small irregular convex surfaces,
