3.1 Insulating materials fitted in the machinery
space of new vessels shall be non-combustible when tested in accordance
with Resolution A.799(19)
footnoteof the International Maritime Organization. Insulating
materials fitted in the engine space of existing vessels shall not
be readily ignitable. Insulation shall be covered with a material
impervious to oil or oil vapour.
3.2 Any insulation composite may be considered
not readily ignitable where the test defined in
Annex 5
is carried out on a representative
specimen and the result is satisfactory. In such testing, the specimen
edge need not be tested where the insulation is fitted without exposed
edges and specimen conditioning may be curtailed as appropriate to
the material under test.
3.3 On existing vessels where insulation is readily
ignitable, it shall be replaced as soon as possible, but not later
than three years of the coming into force of the Code.
