Prior to the test, the following information should be submitted
to the laboratory by the applicant for each of the materials used
in the construction:
- the identification mark and trade name;
- principal details of composition;
- nominal thickness;
- nominal density (for flexible materials this should be related
to the nominal thickness);
- nominal equilibrium moisture content (at relative humidity of
50% and a temperature of 23°C);
- specific heat at ambient temperature;
- thermal conductivity at ambient temperature.
The density of each material used in the test specimen should
be within ± 10% of the value stated as the nominal density.
Where materials used in the construction of the specimen
are required to be non-combustible, i.e. for "A" class and "B" class,
evidence in the form of test reports in accordance with the test method
for qualifying marine construction materials as non-combustible, developed
by the Organization, and from a testing laboratory recognized by the
Administration and independent of the manufacturer of the material
should be provided. These test reports should not be more than 24
months old at the date of the performance of the fire resistance test.
If such reports cannot be provided then tests as prescribed in 3.2.3 below should be conducted.
