In addition to accredited tests, the DZS can simulate operating conditions of components and assemblies according to a test program (of the customer) or test room. Tests can be performed on small parts as well as on complete units such as the entire expansion field or complete railway wagons.

 

 PERFORMED TESTS - NOT ACCREDITED 

  • functional test of the dilatation field,
  • measurement of damper characteristics (all sizes),
  • functional tests of switch-point machines,
  • and other tests as specified.
