Thermal & mechanical testing |
| Material testing is performed for both material evaluation and quality control. For testing and characterization of materials a catalogue is available. Extensive quality control programmes, including sampling, visual inspection and dimensional control, are carried out on an hour basis or fixed price. The skilled staff ensures the consistency of the test procedures, the quality of the data produced and the reliability of the test results. The tests can be performed according to ISO-EN, PRE, ASTM and DIN standards. |
