Watch the video of the laboratory tests:
pH determination test on the skin: Allows you to determine the real pH value of the skin, which must be between 3.5 and 4.5.
Oxidation test: Establishes the propensity of metal surfaces to oxidize in contact with skin or water. No oxidation is permitted.
Color fastness test to water and sweat: Used to determine the color fastness of the product in contact with water and sweat. Any color transfer on the fabrics used in clothing is checked.
Veslic test on leather: Useful for determining the resistance of each type of leather to wear, abrasion or color transfer. The leather sample is tested both dry and wet and under a removable weight of 1 kg.
Leather resistance test to stains: The leather's reaction to stains is determined by pouring small drops of water on its surface, checking every 30 minutes and after 24 hours. No blemishes, marks or ripples on the leather are permitted.
Metal Finish Strength Test: Evaluate the strength of the finish on the metal accessory by simulating normal deterioration. A cut is made with a cutter and the behavior of the finish is observed.
Salt spray resistance test: Establishes the propensity of metal surfaces to oxidize or damage the finish due to exposure to salt spray (fog at 47°C - test duration: 24h). No oxidation is permitted.
Leather finish strength test: Tests the strength of the leather finish. A layer of adhesive tape is applied to the surface and, after peeling it off, the integrity of the leather is checked.
