Leather - Chemical, physical and mechanical and fastness tests - Sampling location1 ScopeThis standard specifies the location, where laboratory samples are cut, from a single (piece) of leather, as well as the method for marking the cut laboratory samples. This standard applies to leather, which is processed from various mammalian skins. This standard does not apply to leather, which is processed from bird, fish, reptile skins.2 Terms and definitionsThe following terms and definitions apply to this standard. 2.1 Laboratory sample Samples, which are taken from the areas specified in Chapter 4.3 Location of laboratory samples3.1 Overview 3.1.1 Selection of samples 3.1.1.1 The area, where the laboratory sample is selected, shall be free from obvious defects of various types, such as scratches and knives from peeling. 3.1.1.2 The sampling procedure applies to sampling for physical, chemical, color fastness tests. 3.1.2 Sampling for physical and color fastness tests Samples for physical and color fastness tests are cut from the areas in Figures 1 ~ 4, where there is no shadow bar. 3.1.3 Sampling for chemical tests 3.1.3.1 The samples for chemical test are cut from the area with shadow bars, in Figures 1 ~ 4. 3.1.3.2 If the minimum sample block, which is required for the chemical test, cannot be obtained, take a sample from the corresponding part on the other side of the back ridge line of the sample. If sufficient samples cannot be obtained, take samples from areas, which are adjacent to the sampling location. 3.1.3.3 Except for arbitration analysis, clean specimens, which are not contaminated during physical testing, may be used for chemical test. In arbitration analysis, leather specimens for chemical test can only be taken from the correct location. 3.2 Whole leather Cut out the square block GJKH without shadow bar AND/OR the square block HLMN with shadow bar, according to Figure 1. In smaller leathers, the distances, EF and JK, which are required for a single specimen, can be shortened appropriately. When sampling from smaller leather, if the sampling method is changed, a minimum deviation from this procedure shall be maintained. 3.3 Half-hip back leather Cut out the square block GJKH without shadow bar AND/OR the square block HLMN with shadow bar, according to Figure 2. 3.4 Shoulder leather Cut out the square block ABCD without shadow bar AND/OR the square block AEFG with shadow bar, according to Figure 3. 3.5 Ventral leather Cut out the square blocks GJKH without shadow bars AND/OR the square blocks LMNG and HPQR with shadow bars, according to Figure 4. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
