Cyclic aging tests

The laboratory can perform the following cyclic aging tests in climate chambers:

  • The aging test according to ISO 20340 (or NORSOK), the artificial aging test for pipelines according to ISO 15741, ISO 11997-2, and various ASTM standards.
  • The ISO 20340 aging test lasts 25 weeks and consists of a cycle of 3 days QUV (alternating 4 h exposure (with UVA) at 60 °C and 4 h condensation at 50 °C), 3 days neutral salt spray (ISO 9227), and 1 day exposure at -20 °C.
  • ISO 11997-2 is a test method for determining the resistance of coatings in a defined cycle of wet (salt spray) / dry / condensation / UV light.
  • ASTM G85 describes 5 variants, including cyclic corrosion tests; we perform all of them.
  • Cyclic tests with temperature variations from -40 °C to +180 °C and RH in a range of 0 to 100% can also be performed by Nebest-COT.

If other standards or specifications are required, please contact Nebest-COT to discuss the possibilities.
