3.6.1
E + L should be
calculated based upon:
-
.1 the results of full scale trials on similar
ships and evacuation systems; or
-
.2 data provided by the manufacturers. However,
in this case, the method of calculation should be documented, including
the value of safety factor used.
3.6.2 For cases where neither of the two above
methods can be used, E + L should be assumed
equal to 30 min.
