7.1 Testing

7.1.1 The requirements of the Rules relating to testing of pressure vessels, piping and related fittings including hydraulic testing are applicable. See Pt 5, Ch 11 Other Pressure Vessels and Pt 5, Ch 12, 8 Hydraulic tests on pipes and fittings.

7.1.2 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.

7.1.3 After installation on board, piping systems together with associated fittings that are under internal pressure, are to be subjected to a running test at the intended maximum working pressure.

7.1.4 Testing is to cover the following items:

  1. Verification of control, alarm and safety systems.

  2. Simulation tests for failure of refrigeration equipment, to verify correct functioning of alarms and systems in service.

  3. Verification of accuracy, calibration and functioning of temperature control for refrigeration systems.

7.2 Trials

7.2.1 Acceptance trials, as stipulated in this Section, are to be conducted. It is to be demonstrated that the provision store or air-conditioning refrigerating system capacity meets the design duty. As far as is practicable, the trials are to represent the operating conditions that will be encountered in service. For example, the condenser cooling water flow should be restricted so that the compressor discharge pressure is at the design value.
