Extensometry :

•	Instrumentation using extensometric gages with in-situ or in the lab interpretation ,
•	Temperature expansion coefficient measurement  using gauges, Determination of residual stress on parts based on the bore method as per   ASTM E 837 in our premises or on site according to part size.
•	check of the bending alignment %.

Calibration :

•	Periodic on-site checks : - presses, test machine cells, weights, scales, extensometers, - lab furnaces and enclosures, thermal treatment ovens   (ventilated ovens, under vacuum, under atmosphere, salt baths), - ageing enclosures, - recorders.
•	periodic  checks in the lab test machine cells, weights, scales, - extensometers, - motion cells.

For all our services,  a check report and/or a calibration certificate including all measurements is produced.


Note : all calibration facilities are periodically checked by agencies approved by COFRAC with tracement to national standards.
