Resistance to surface wetting
This test is used to evaluate leather water repellence Leather / LeathergoodsColor fastnessEN ISO 17231 Color fastness to water spotting
Water can cause deterioration of both the colour and the internal structure of leather (swelling). This test is used to check the sensitivity of leather and its finish to spots of water deposited on the surface. Leather / LeathergoodsColor fastnessEN ISO 15700 Color fastness to water
This test is used to evaluate the staining (transfer) from leather via contact with various types of fabric in the presence of water. LeatherColor fastnessEN ISO 11642 Color fastness to perspiration
This test is used to evaluate the staining (transfer) from leather via contact with various types of fabric in the presence of alkaline sweat. Leather / LeathergoodsColor fastnessEN ISO 11641 Color fastness to light (each additional 24h)
This test is used to anticipate any colour deterioration that might occur due to exposure to light. This test is based on EN ISO 105B02. LeatherColor fastnessCTC method - CTC-P-DV-01 Color fastness to light (until 72h)
This test is used to anticipate any colour deterioration that might occur due to exposure to light. This test is based on EN ISO 105B02. LeatherColor fastnessCTC method - CTC-P-DV-01 Color fastness to rubbing (dry and wet conditions)
This test is used to determine the amount of color transferred from the surface of a colored leather to other surfaces, by rubbing.two rubbing tests are carried out: one with a dry standardized white cotton rubbing cloth and the other with a wet standardized white cotton rubbing cloth. This method applies to all types of colored leather. Leather / LeathergoodsColor fastnessEN ISO 20433 Color fastness to rubbing (sweat condition)
This test is used to check whether repeated rubbing is able to cause deterioration of the leather colour, on the one hand, and whether the colour can run (transfer) onto the backing material. Leather / LeathergoodsColor fastnessEN ISO 11640 Color fastness to rubbing (wet condition)
This test is used to check whether repeated rubbing is able to cause deterioration of the leather colour, on the one hand, and whether the colour can run (transfer) onto the backing material. Leather / LeathergoodsColor fastnessEN ISO 11640 Color fastness to rubbing (dry condition)
This test is used to check whether repeated rubbing is able to cause deterioration of the leather colour, on the one hand, and whether the colour can run (transfer) onto the backing material. Leather / LeathergoodsColor fastnessEN ISO 11640 Static absorption of water
This test used to determie the water absorption of leather under static conditions.The absorption of water by a leather during immersion is one of its comfort characteristics. This test is suitable for all types of leather used in footwear manufacture. LeatherComfortEN ISO 2417 Water vapour absorption
Leather has beneficial comfort properties, including water vapour absorption, which is particularly prized for instance in shoe linings. This test is used to quantify the intrinsic capacity of leather to absorb water vapour. LeatherComfortEN ISO 17229 Water vapour permeability
This test is used to quantify leather breathability, by evaluating the quantity of water vapour that can potentially pass through it. LeatherComfortEN ISO 14268 Water resistance of heavy leathers
This test is used to check the water resistance of leather soles to ultimately ensure that the wearer’s feet will remain dry. LeatherComfortEN ISO 5404 Water resistance
This test is used to measure the water resistance of flexible leather. It evaluates both the water penetration time and the quantity potentially absorbed. LeatherComfortEN ISO 5403-1
