This approval is for bonding safety critical rail vehicle parts which covers applications where there is a risk of endangering passengers due to part failure in use. TRB, which is IRIS (International Railway Industry Standard) approved, has for over 60 years been manufacturing high quality rail interior products. These are used in new and refurbished trains and transportation systems worldwide.
The DIN 6701 A1 rating, certified by TBBCert, has been achieved for the main Huntingdon facility, where TRB designs and manufactures lightweight metal and composite parts, as well as complete assembled interior units for passenger train interiors and other rolling stock. Attaining the top level (A1) approval enables TRB to bond any product required in a rail vehicle under any of the four DIN 6701 A1-3 and Z type classifications. Safety critical products needing A1 approval that are manufactured and supplied by TRB, include emergency detrainment door systems and passenger exit doors.
