The extended Mercedes-Benz Türk A.Ş. bus and coach plant in Hoşdere: Equipped with highly sophisticated technology, the three new material laboratories at the Hoşdere plant are a vital part of the extensive programme implemented to further improve product quality. As well as being responsible for all bonding processes at the Hoşdere plant, the laboratory for non-metallic materials assesses the tensile strength, pressure resistance, bending resistance, tear strength and adhesion of all non-metallic materials such as fabrics, rubber, wood, plastics and such like. It also carries out flame-retardance tests and tests for determining the resistance of materials using an ozone tester, for example.
