The laboratory team is made up exclusively of engineers and doctor-engineers trained in the fields of physical measurements, material mechanics and metallurgy who will provide you follow-up and advice throughout the project :
SONATS is both ISO9001 and EN9100 certified. All analyses are performed according to the current standards in force and according to the recommendations of international standards:
– Residual stress measurements by X-ray diffraction: NF EN 15 305
– Residual stress measurements by incremental hole drilling strain gauge method: ASTM E837
– Materials analysis: Standard according to methods
– Dimensional control: Standard according to methods
The laboratory is qualified by the SAFRAN aeronautical group to carry out residual stress measurements using X-ray diffraction. The measurement devices are checked before each series of measurements on qualified reference samples via inter-laboratory comparisons with other French and European laboratories. Control cards are used to validate the maintenance of the quality of the measurements for the various devices and by laboratory operators.
The structure of SONATS ensures a service with controlled costs and in the shortest times.
Answer to initial contact in 48 hours.
The standard time for a punctual analysis of residual stresses.
The reduced period guaranteed for your regular inspections if a framework contract is established: 24 hours to provide you with the results.
Our partner and manufacturer, StressTech, is an international expert in the field of material health analysis and stress measurement equipment.
The laboratory team maintains active technical and scientific monitoring to ensure the highest level of our services. The laboratory also participates in several R&D groups and programs dealing with residual stresses and mechanical surface treatment processes.
