Rail
The field of railway construction requires materials and systems to be ever more innovative, reliable and robust. Technological advances are also made in the manufacturing process.
Normative standards differ in comparison with the aeronautical sector, but the requirements meet. Studies and tests are therefore feasible with the same equipment and the same skills. The objectives of mechanical dress, weight gain, fire resistance, electronic reliability, are identical and problems of wear or degradation related to the frequency of passage of users (floors, seats, ramps) must be added.
The railway industry is increasingly using composite materials. Recoll describes these materials and carries out all the tests required by the most requested repositories in this field.
In particular, Recoll, accredited laboratory COFRAC (COFRAC accreditation N ° 1-1995) carries out all the tests of the standard NF F 01-281:
