Control test of dimensional variations

Evaluation of the variation in dimension of the components, subjected to thermal ageing.

Additional evaluation generally performed in conjunction with temperature, humidity or thermal cycling aging tests.

These environmental tests are often required in the vehicle set-up, in order to understand the behavior of the component in its daily life, as it should eventually be mounted in the car.

However, to carry out the dimensional stability tests, conditioning may be required in the absence of vehicle set-up.
