An average (D
m) of the maximum of D
s of three tests at each test condition should
be calculated.
-
.1 For materials used as surface of bulkheads,
linings or ceilings, the D
m should not exceed
200 in any test condition.
-
.2 For materials used as primary deck covering
or surface of floor, the D
m should not exceed
400 in any test condition.
-
.3 For plastic pipes and electric cables, the D
m should not exceed 400 in any test condition.
