CD tests

Cathodic protection tests or cathodic disbondment tests (CD tests) may be carried out according to various standards. A standard that is frequently used is ISO 15711 with a testing period of 25 weeks.

A number of ASTM standards ASTM G 8, ASTM G 42 and ASTM G 95 or derivative specifications with different testing periods; 24 hours, 48 hours, 30 days or 90 days are common testing periods. The requested temperatures range from room temperature until over 100 °C.

The NORSOK system 7C specification has CD tests for 3 temperatures / temperature ranges. The default is 6 months at room temperature, but in addition there is a test of 4 weeks at a temperature between 50 and 100 °C, and the third option is the high temperature HTCD test, 4 weeks, testing at a temperature between 100 and 180 °C. The temperature gradient over the test panel is 150 °C. In 2014 COT has acquired a laboratory test setup for this high temperature HTCD tests.
