Continuity in IRIS certification

As in previous years, Dinghan SMART Railway Technology GmbH successfully passed the re-certification audit of the national standard ISO/TS 22163 (IRIS) in 2021. The auditors from Bureau Veritas confirmed the "International Railway Industry Standards" certificate first awarded to the manufacturer of auxiliary power converters in 2011. The IRIS standard is an internationally applicable requirement for the quality management systems of railway manufacturers. More information on IRIS is available at http://www.iris-rail.org/.
