The corrosion tests increased their importance both for the materials homologation and the failure analysis. It is very important during corrosion tests to operate according to the referenced standards and to check the test parameters in order to obtain reliable and repeatable results. OMECO offers the warranty of the ACCREDIA accreditation for most of the corrosion tests listed here below. Moreover its know-how and its qualified personnel permit also to study and to perform "special" corrosion tests for any kind of materials. OMECO has wide chambers which are suitable for Salt Spray (Fog) tests and climatic tests.
