Laboratory

The Compreforme Stratiforme Group has a laboratory recognized by the French accreditation authorities and by international mutual recognition.

This laboratory is certified by the European body Certify for railway tests.

The laboratory has built up an important database over several decades through its regular testing work on manufactured parts and representative samples.

Type testing

– Global validation based on specifications

– Validation of a composite material for various applications (rail, defence, aeronautics, etc.)
