Section 16 Tests

1601. Tests at the manufacturer's work 【See Guidance】

1. Boilers and pressure vessels are to be tested in accordance with the requirements in Pt 5, Ch 5 of the Rules.

2. Pipes, valves and other fittings used for compressed air piping having a maximum working pressure exceeding 2 MPa are to be tested with hydrostatic pressure of 1.5 times the maximum working pressure after completion of welding, bending or machining.

3. Valves, cocks and casting distance pieces fitted to the shell plating of the barge below the load water line are, after finished, to be tested with hydrostatic pressure of 0.5 MPa.

4. Fuel oil tanks with their fittings which do not form a part of the ship's structure are to be tested

with a hydrostatic pressure corresponding to a head of water not plates.

5. Generators, switchboards, motors and their starters and transformers to be tested in accordance with the requirements in relevant Chapter

less than 2.5 m above the to

Classification of Steel Ships. Voltage regulation of generators and transformers at load character- istics test is to be in accordance with the discretion of the Society.

6. Cables are to be tested in accordance with the requirements in Pt 6, Ch 1, Sec 4 of the Rules for the Classification of Steel Ships.

7. Explosion-protected electrical equipment is to be subjected to the tests prescribed in Pt 6, Ch 1,

109. 1. (2) of the Rules for the Classification of Steel Ships.

1602. On board tests

1. Popping test and accumulation test for safety valve of boiler are to be carried out in accordance with the requirements in Pt 5, Ch 5, 124. of the Rules for the Classification of Steel Ships.

2. Piping systems including pumps, strainers and heaters for fuel oil, lubricating oil, cargo oil and others used for inflammable oil are to be subjected to test, after installed on board, with hydro-

nected to the pumps which have been subjected to hydrostatic test before assembled on board, may be omitted except for fuel oil piping systems, provided that the leakage tests are carried out at op- erating conditions.

3. Other piping systems together with fittings are, after installed on board, to be subjected to trial.

4. Important systems are, after installed on board, to be subjected to performance test synthetically.

5. Electrical equipment is, after installed on board, to be subjected to insulation resistance test in ac- cordance with requirements in Pt 6, Ch 1, 1801. of the Rules for the Classification of Steel Ships

6. Various safety devices prescribed in each Paragraph are, after installed on board, performance test.
