Mechanical characterization tests

⁰¹Prerequisites

You wish to carry out the mechanical characterisation of your materials as part of production monitoring, the validation of parts or materials, or your R&D:​

Etim carries out mechanical tests in accordance with the various existing standards or to our customers’ own specifications on composite materials, polymers and rubber, wood composites, ceramic matrix composites, etc.​

Our COFRAC ISO 17025  (Accréditation Essais N°1-5242 – portée disponible sur www.cofrac.fr) as well as our specific customer accreditations (AIRBUS, SAFRAN, DASSAULT, etc.) cover a wide range of tests.​

We can handle all aspects of specimen preparation for you, as well as the development of test methods or the design of tooling specific to your needs in line with existing standards or your own specifications.​

Our in-house resources also enable us to carry out measurements at temperatures ranging from -60°C to 250°C. ​

These capacities are extended to -185°C and +360°C on certain machines.​

For tests requiring the acquisition of specific data, we are also able to instrument preparation of specimens by coupling them with equipment such as:​

• Extensometers​
• Deformation gauges​
• 3D video correlation cameras (particularly for measuring deformation fields, etc.)​
• Detection by acoustic emission (detection of first breaks, etc.)​

​Our laboratory is also equipped with:​

• a pendulum impact testing machine to meet the specifications of the Charpy and IZOD shock standards​
• a drop tower for making an impact.​
• Hardness and roughness measurement​
• ​

Etim can meet your serial production monitoring needs by carrying out tests within short deadlines ranging from 3 to 10 days maximum.​

To achieve this, our laboratory is operational all year round with teams working 2*8.​
