Certified reference standards

For calibrating the test systems, for eddy current tests as well as other NDT methods, certified reference standards with defined adjustment errors are required. For this purpose, DELTA TEST produces certified reference standards from metallic materials through processing by spark erosion machining for its own requirements as well as by customer order.

The extent of the artificially created defects follows individual customer specifications and can be adapted to the defects to be expected. For these tasks, a state of the art 3-axis eroding machine and qualified personnel is available.
