1.5.1 Where the Code requires that a particular
fitting, material, appliance, apparatus, item of equipment or type
thereof should be fitted or carried in a unit, or that any particular
provision should be made, or any procedure or arrangement should be
complied with, the Administration may allow any other fitting, material,
appliance, apparatus, item of equipment or type thereof to be fitted
or carried, or any other provision, procedure or arrangement to be
made in that unit, if it is satisfied by trial thereof or otherwise
that such fitting, material, appliance, apparatus, item of equipment
or type thereof or that any particular provision, procedure or arrangement
is at least as effective as that required by the Code.
1.5.2 When an Administration so allows any fitting,
material, appliance, apparatus, item of equipment or type thereof,
or provision, procedure, arrangement, novel design or application
to be substituted hereafter, it should communicate to the Organization
the particulars thereof, together with a report on the evidence submitted,
so that the Organization may circulate the same to other Governments
for the information of their officers.
