CD tests

Cathodic protection tests or cathodic disbondment tests (CD tests) can be performed according to various standards.

A widely followed standard is ISO 15711, which is typically conducted for a duration of 25 weeks. In addition, there are several ASTM standards such as ASTM G8, ASTM G42, or ASTM G95, or specifications derived from these, for which the duration can vary; 24 hours, 48 hours, 30 days, and 90 days are common testing periods. The required temperatures for these tests range from room temperature to over 100°C.
