METHODS OF TEST FOR PAINTS AND VARNISHES : PART F10 : DETERMINATION OF RESISTANCE TO CATHODIC DISBONDING OF COATINGS FOR USE IN MARINE ENVIRONMENTS
This Malaysian Standard describes a method of test for determining the resistance to
cathodic disbonding of a single coating or multi-coat system of paint, varnish or other organic
coating applied to metallic substrates when the surface coating covering the metal substrate
may contain or develop discontinuities. It is applicable to coatings that are subjected to
marine environments, such as those on ships or partially exposed marine structures.
NOTES:
1. For coatings that are used to protect land-based metallic structures, the conditions of the test differ from those for
coatings to be used in marine applications. MS 133: Part F11 describes a method suitable for assessing coatings
applied to buried structures.
2. The test result may be influenced not only by the properties of the coating system under test, but also by the
nature and preparation of the substrate, the method of application of the coating system and other factors.
