About us
The Residual Stress Measurement Laboratory (LMTR) is an analysis lab of the residual stresses that are present in certain materials.
The LMTR are working for external customers since 2000, and it is completely committed to offer the maximum quality results.
What we do?
The technique employed by the laboratory for the measurement of residual stresses is X-ray diffraction, in accordance with the criteria established in the UNE-EN 15305 standard.
Using this technique, residual stresses can be measured non-destructively on the surface of the material. Residual stresses can also be measured in depth by removing layers of material in a controlled manner through electropolishing. In this way, a stress profile in depth can be obtained up to approximately 500 mm. The scope of the laboratory includes the analysis of residual stresses in metallic materials or crystalline ceramic materials. Our personnel are perfectly qualified to carry out the tests and tasks necessary for the analysis of this type of materials.
The laboratory has the PROTO iXRD Portable residual stress analyzer diffractometer for carrying out the tests.
Accreditations
The LMTR is accredited by ENAC under the UNE-EN ISO/IEC 17025 (Accreditation No.: 1308/LE2435) for the analysis of residual stresses in metallic materials or crystalline ceramic materials.
To our knowledge, the LMTR is the only laboratory in Spain accredited under the UNE-EN ISO/IEC 17025 standard for the measurement of residual stresses by X-ray diffraction.
In addition, the LMTR is accredited within the CAM Laboratory Network as aTesting Laboratory with traceability category (nº 348).
