The GTS certificate, is the only certificate worldwide which, in addition to the quality management elements of DIN EN ISO 9001:2000, includes a personnel, process and, on request, also a product certification for thermal spraying. The rules for certification were worked out by the thermal spray users, i.e. GTS members, themselves and have proved to be very effective. Today, the GTS certificate serves as a basis for assessing a certified GTS member should inconsistencies or legal disputes arise. The certificate demonstrates that the certified company has a visible quality standard and that it also meets specified quality requirements in its day-to-day business operations.
