The business unit "Railway Technology" of Burisch Elektronik Bauteile GmbH with the LED lighting system SCHURTER TrenoLux was certified according to IRIS ISO/TS 22163 at the first attempt in 2021. Behind this stands a quality management model that is tailored specifically to the railroad industry and its suppliers.

IRIS stands for "International Railway Industry Standard". With the IRIS standard, the Brussels-based "Union des Industries Ferroviaires Européennes" (UNIFE), in cooperation with leading rail system manufacturers, developed an internationally applicable requirement for quality management systems for the first time in 2006. This set of rules applies not only to rail system manufacturers, but to the same extent to their suppliers and engineering service providers. They, as well, can be certified according to the same requirements.

A lot of time has passed since 2006. The requirements have increased and the regulations have been revised and adapted several times. The current version is called IRIS ISO/TS 22163.
