7.1 Each oil content meter and each control section
of a monitoring system should be subjected to a functional test on
a suitable test bench prior to delivery. The detailed programme for
a functional test of such equipment should be developed by the manufacturer,
taking into account the features and functions of the specific design
of equipment. A completed workshop certificate including the delivery
test protocol should be supplied with each unit delivered.
7.2 A functional test conducted on an oil content
meter should include at least all the following operations:
-
.1 check flow rate, pressure drop or an equivalent
parameter as appropriate;
-
.2 check all alarm functions built into the meter;
-
.3 check all switching functions interconnecting
with other parts of the system; and
-
.4 check correct reading at several ppm values
on all measurement scales when operated on an oil appropriate for
the application of the meter or by an equivalent method.
7.3 A functional check conducted on a control
section of a monitoring system should include at least all the following
operations:
-
.1 check all alarm functions;
-
.2 check correct function of the signal processor
and the recording equipment when simulated input signals of ppm, flow
rate and speed are varied;
-
.3 check that the alarm is activated when the
input signals are varied so that the discharge limits contained in regulation 9(1)(a)(iv) and (v) are
exceeded;
-
.4 check that a signal is given to the overboard
discharge control when alarm conditions are reached; and
-
.5 check that the alarm is activated when each
one of the input signals is varied to exceed the capacity of the system.
