Quality Management System ISO 9001
The high quality standard of starline®'s technical equipment and application is the basis for the economic success of the licensed technologies. All trenchless technologies are therefore certified in accordance with DIN EN ISO 9001. Detailed instructions and a comprehensive training program insure the technology's high quality standard. Custom-made quality management systems are developed for each technology to guarantee the application's quality by independent and built-in monitoring systems. In addition the licensor has also developed a comprehensive quality assurance system for the required materials and technical equipment insuring the consistently high quality of all materials by an incoming and outgoing merchandise monitoring system.
Prior to releasing new developments and optimized technical procedures, these developments are subject to comprehensive inspections and tests on the licensor's construction sites in Europe. Thus making sure that sTT's customers obtain only fully developed systems.
In addition to European testing, tests were conducted in 1998 to evaluate the starline® product and installation process. Tests were designed by GRI and IGT, conducted at Brooklyn Union Gas company in Brooklyn, New York, and witnessed by representatives from leading utilities and contractors in the U. S. Furthermore, longterm tests have been performed by Battelle Institute, a prominent technical organization in the U.S. Both the product and process were deemed "fit" for the purpose of rehabilitating gas pipes in the U.S.
