Testing laboratory was established by Bombardier Transportation Czech Republic a.s. in 2011. Main reason was ability to test welding joints independently of external laboratories.
The accreditation process with the ČIA – Czech Institute for Accreditation was completed in September 2013 and the Laboratory acquired The Certificate of accreditation. The BTCZ Testing Laboratory is preceded under the No 1646 with the ČIA. During December 2014, the laboratory was relocated to the new building. In July 2015 the extension of accreditation for two methods (transverse tensile test and bend test of the welded joints) was done. The accreditation scope includes currently five test methods which are listed in the section "What we offer" and in Annex to the Certificate of Accreditation.
