ISO 15711 Cathodic Disbonding testing of marine coatings at AWL
We are pleased to offer two methods for determining the ability of paint, or other organic coatings, applied to metallic substrates to withstand cathodic disbonding when the surface coating may contain or develop discontinuities.
The methods are applicable to coatings that are exposed to sea water, such as those applied to ships or marine structures that require ISO 12944-9 qualification to CX categories and beyond.
Method A involves the use of a cathodic protection circuit, whereby the electrode potential of the test substrates is controlled potentiostatically.
Method B involves the use of sacrificial anodes attached to the test substrates. This reflects the practical method of cathodic protection commonly used on ships.
