    VTT Expert Services Ltd performs accelerated weathering tests for metal coatings, protective paintings and various other materials. In corrosion testing salt mist is sprayed as corrosive substance.  In UV-test the specimen is stressed with UV- or Xenon Arc radiation, heat, water spray and condensation. The accelerated ageing conditions and test program is planned to meet the needs of the customer specification and relevant testing standards.

    Assessment of surfaces and materials

  • Measurement of the coating thickness before the test
  • Pull-off test for adhesion of a coating, EN ISO 4624, before and after the ageing
  • Visual assessment and evaluation of degradation of coatings EN ISO 4628-2, EN ISO 4628-3, EN ISO 4628-4, EN ISO 4628-5, EN ISO 4628-6,
  • Determination of corrosion from a scratch on the surface, EN ISO 4628-8 and etc.
  • Colour and gloss measurement, changes
  • Determination of mechanical properties (e.g. impact tests, tension properties) of material before and after the tests
