There are several Cyclic aging tests which can be performed in climate chambers at the COT laboratory:
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 aging test according to ISO 20340 takes 25 weeks and has a cycle of 3 days QUV (alternating 4 hours exposure (with UVA) at 60 °C and 4 hours condensation at 50 °C), 3 days neutral salt spray (ISO 9227), and 1 day exposition at -20 °C. The ISO 11997-2 is a test method to determine the resistance of coatings in a defined cycle of wet (salt spray) / dry / condensation / UV light.
ASTM G 85 describes five varieties, including corrosion-change test.
Also cyclic tests with variations in temperature from -40 °C to +180 °C and RH in a range of 0 to 100 % are possible
When other standards or specifications are required, the COT Laboratory will gladly investigate the possibilities of performing these tests.
Over the years, the demand for paint testing at high pressure and temperature in combination with corrosive gases increases. In various standards and specifications such as ISO 15741, EN 10289, EN 10290, ARAMCO 09-SAMSS-067 APCS 27, [...]
