5.1.2 On completion, tanks and reservoirs for service and storage of system fluids are to
be tested by a head of water equal to the maximum to which the tanks may be
subjected, but not less than 2,5 m above the crown of the tank.
5.1.3 After installation on board, piping systems that are under internal pressure, are to
be subjected to a running test at the intended maximum working pressure.
5.1.4 Testing is to cover the following items:
- Verification of control, alarm, safety systems.
- Tests simulating failure of fresh water production equipment and pumps to
verify correct functioning of alarms and systems in service.
- Verification of accuracy, calibration and functioning of temperature control
for hot water heating, monitoring and recording instrumentation for sea
water desalination plants where fitted.
5.1.5 Fresh water systems for potable water are to be cleaned and sterilised
after testing in accordance with equipment manufacturer's installation instructions
and a recognised National or International Standard e.g. BS 7593 Code of practice
for treatment of water in domestic hot water central heating systems. The
quality of potable water is subsequently to be tested by an accredited laboratory to
confirm that the water quality meets that defined in Pt 5, Ch 26, 1.1 Definitions 1.1.1.(b). Separate
water samples are to be taken from the outlet of the sea water desalination plant
and at an outlet from the potable water storage tank using water which has been in
the tank for not less than 24 hours.
