Watch strap usage simulation
Simulate all situations of use associated with the use of a watch strap: pulling, twisting, strap sliding into loop, pin insertion into strap, exposure to perspiration, rubbing of strap against clothing, etc. Observe any damage to the tested watchband (abrasion, elongation, loss of color). LeathergoodsPerformanceExpertise Corrosion of metal accessories
This test is used to determinate the propensity of a metal surface to corrode due to the action of salt water BeltPerformanceEN ISO 22775 Méthode 2 Damp heat - 40° - 96% HR (72 hours) with intermediate rating
The purpose of this determination is to assess the wet heat behaviour of a whole item, of a material sample or of an assembly. This test is in particular highly useful for evaluating the risk of corrosion of metal parts in the presence of leather materials. BeltPerformanceCTC method - CTC-P-P-025 Resistance of the buckle
The purpose of this determination is to assess the quality of the fixation of a buckle from a belt. BeltPerformanceCTC method - CTC-P-MA-015 Resistance of barb
The purpose of this determination is to assess the quality of the fixation of the tongue of a buckle from a belt. BeltPerformanceCTC method - CTC-P-MA-015 Spring resistance / reversibility ressort
The purpose of this determination is to judge the quality and fixing of the reversibility spring. BeltPerformanceCTC method - CTC-P-MA-015 Color fastness to rubbing (wet condition) - 50 cycles
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) on to the backing material. BeltPerformanceEN ISO 11640 Color fastness to rubbing (dry condition) - 100 cycles
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) on to the backing material. BeltPerformanceEN ISO 11640 Flex resistance under load
This test reproduces the stresses to which the materials are subjected during flexing movements, and is used to check that the backing materials have suitable finishes, coatings, etc. It is particularly relevant for shoulder straps, handles, belts, watch straps, etc. For belts, this test simulates opening and closing movements. BeltPerformanceBS 5131 § 4.2 Tear resistance (longitudinal cut)
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. BeltPerformanceEN ISO 3377-1 Water vapor permeability of whole footwear
This test is used to check the breathability not of the materials taken individually, but of the whole shoe. This means measuring the water vapour evacuation that the wearer will experience. FootwearPerformanceCTC method - CTC-P-CH-013 Resistance of outsole after compression cycles (running)
The objective of this test is to apply compression ageing to the rear part of a shoe sole (heel), by reproducing the impacts that occur when running. FootwearPerformanceCTC method - CTC-P-CH-018 Resistance of outsole after compression cycles (walking)
The objective of this test is to apply compression ageing to the rear part of a shoe sole (heel), by reproducing the impacts that occur when walking. FootwearPerformanceCTC method - CTC-P-CH-018 Cold insulation
This test verifies a sole's ability to insulate against cold environments. FootwearPerformanceEN ISO 20344 Water resistance of footwear
This test is used to determine the water resistance of the shoe as a whole. The test simulates walking in wet grass. FootwearPerformanceCTC method - CTC-P-CH-005
