BS EN ISO 2589:2016 specifies a method for determining the thickness of leather. The method is applicable to all types of leather of any tannage. The measurement is valid for both the whole leather and a test sample.

5 Sampling and sample preparation
5.1 Official sample in accordance with ISO 2418. Five measurements to be taken, distributed across the sample.
5.2 Sample prepared for other tests. Three measurements to be taken, distributed across the sample 5.3 Sample of unknown origin. Five measurements to be taken, distributed across the sample.
5.4 For very heavy, firm leathers, a smaller sample is recommended to avoid curvature. Three measurements to be taken, distributed across the sample.
5.5 For whole hides, five measurements for each location should be taken Condition all samples in accordance with ISO 2419.
6 Procedure
Place the apparatus on a flat, horizontal surface. Place the sample in the gauge grain side up if this can be identified. If the grain cannot be identified place the sample in the gauge with either surface upwards. Apply the load gently and record the thickness 5s+ 1s after full loading is reached.
7 Expression of results
The results shall be expressed as the arithmetic mean and range to the nearest 0,01 mm.
