Product Tests:
- SKIN PH DETERMINATION TEST: 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 due to contact with skin or water. No oxidation is permitted.
- COLOR RESISTANCE TEST TO WATER AND SWEAT: It is used to determine the color fastness of the product to contact with water and sweat. The possible transfer of color on the fabrics used in clothing is checked.
- VESLIC LEATHER TEST: Useful to determine the resistance of each 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 reaction of the leather to stains is determined by pouring small drops of water on its surface and checking every 30 minutes and after 24 hours. No stains, marks or waves on the leather are permitted.
- METALLIC FINISH RESISTANCE TEST: Evaluates the resistance 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 evaluated.
- SALT MIST RESISTANCE TEST: Establishes the propensity of metal surfaces to oxidize or damage the finish due to the effect of salt spray (fog at 47°C - test duration: 24h). No oxidation is permitted.
- LEATHER FINISHING RESISTANCE TEST: Checks the resistance of the leather finishing. A layer of adhesive tape is applied to the leather and after tearing it off, the integrity of the leather is checked.
