Pulling strength of reinforcing rows
The purpose of this determination is to assess the quality of reinforcing rows on materials. Leathergoods / LuggageMechanical resistanceNF G 92 004 Breaking strength of seams
The purpose of this determination is to assess the quality of seams made on luggage items. Leathergoods / LuggageMechanical resistanceNF G 92 003 Tear strength of constituent materials
The purpose of this determination is to assess the quality of the constituent materials of the items, and thereby form an opinion on their in-use behaviour. Leathergoods / LuggageMechanical resistanceNF G 92 002 Adhesion resistance of glued parts
This test is used to evaluate the resistance of glued joints between various parts. This test can be performed as-is or after ageing. LeathergoodsMechanical resistanceEN ISO 17708 Abrasion resistance - Martindale method
Leather goods can be subjected to friction stresses that might cause premature wear of the constituent materials. The purpose of this test is to qualify the components, (linings, upper...), in terms of abrasion resistance. LeathergoodsMechanical resistanceCTC method - CTC-P-CU-028 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 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 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 Repeated flex resistance (wet condition)
This test reproduces the stresses to which the materials are subjected during flexing movements, and is used to check the behaviour of the materials, their coatings finishes. It is particularly relevant for shoulder straps and handles. Leather / LeathergoodsMechanical resistanceEN ISO 5402-1 Repeated flex resistance (dry condition)
This test reproduces the stresses to which the materials are subjected during flexing movements, and is used to check the behaviour of the materials, their coatings finishes. Leather / LeathergoodsMechanical resistanceEN ISO 5402-1 Determination of tear load trouser test piece
The tear strength is an important parameter for shoes, leather and leather goods. Leather items are subjected to stresses in assembly or in use. This method is used evaluate the tear resistance of leather. Leather / LeathergoodsMechanical resistanceEN ISO 3377-1
