In the GMW 14445 standard, developed by the General Motors company, which includes brands such as Buick, Cadillac and Chevrolet, a test method is defined to determine the resistance of vehicle interior materials to sunscreen and insect repellent. This test method is mainly used for organic coated interior plastic materials that are prone to contamination by sunscreen and insect repellent due to contact with human skin. The test method is also used for organic coated metals.
The materials used in the interior of the vehicles need a protective coating to make them look new. This includes protection against sun exposure and perspiration, and sunscreen and insect repellent transferred from human skin to vehicle surfaces. A series of durability tests are conducted to help ensure that a vehicle's carpet, leather and fabric seat upholstery, wood and metal upholstery, plastics and other materials are less subject to fading, discoloration, or premature wear from these and other substances. In advanced laboratories, durability and resistance tests to natural and artificial elements are carried out on visible and invisible materials in the vehicle. It's not just exposure to the sun or moisture, but also common spills like ketchup and mustard, and stronger chemicals found in sweat, sunscreen, and often insect repellent.
The GMW 14445 g sun protection and insect repellent resistance test is applied to assess how well protective coatings on dashboards, steering wheels, or upholstery resist sunscreens and chemical compounds. To test material durability under heat and ultraviolet light, samples are exposed to artificial light for 2-6 weeks before analysis. Simulated ultraviolet light significantly speeds up the test. However, natural sunlight testing is necessary to definitively confirm durability.
Our organization also provides sunscreen and insect repellent resistance testing services within the scope of GMW 14445 standard, with its trained and expert staff and advanced technological equipment, among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors.
