The Testing Laboratory of material properties (No. 1151) is accredited by the Czech Accreditation Institute (CAI) as per CSN EN ISO/IEC 17025 and it holds a Certificate from General Electric Aircraft Engines.
The Laboratory is a member of the Association of Czech Testing Centers and Laboratories and the largest testing laboratory of the company with unique equipment for testing the properties of construction materials.
Laboratory Profile:
The laboratory conducts experimental research, development, testing and consultancy in the field of increasing reliability, reducing the material costs of structures and components exposed to static and dynamic stress under different conditions.
- determination of basic mechanical and fracture properties according to CSN and foreign standards at normal, low and high temperatures up to 1000 ° C
- detection of low and high cycle fatigue properties of materials at normal, lower and higher temperatures up to 1000 ° C, interaction of fatigue and creep, investigation of damage mechanisms
- thermal fatigue
- assessing the admissibility of defects, detecting crack propagation data and thresholds, assessing residual life of parts with defect
- determination of fatigue strength and life of components, increase of fatigue strength by surface treatments
Laboratory activity:
