3.2.1 The selection of a coating should be considered
by the parties involved with respect to the service conditions and
planned maintenance.
3.2.2 The following aspects, inter alia,
are to be considered:
-
.1 location of tank relative to heated surfaces,
-
.2 frequency of ballasting/deballasting operations;
-
.3 required surface condition
-
.4 required surface cleanliness and dryness; and
-
.5 supplementary cathodic protection, if any.
3.2.3 Coating manufacturers should have products
with documented satisfactory performance records and technical data
sheets. The manufacturers should also be capable of rendering adequate
technical assistance.
3.2.4 For products without satisfactory performance
records, coating selection should be supported by appropriate test
data carried out in accordance with recognized standards in order
to verify their suitability to the service conditions (e.g. immersion,
accelerated hot salt spray and adhesion tests).
3.2.5 Coatings for application underneath sun-heated
decks or on bulkheads forming boundaries of heated cargo spaces should
be able to withstand constant or repeated heating without becoming
brittle.
3.2.6 Due regard should be given to the possible
poor edge covering properties of hard coatings with a high solid content.
