Section 13 Air Compressors

1301. Application

1. Where the manufacturer obtained the Approval of Quality Assurance System specified in Ch 5 of the Guidance apply to the Type Approval of air compressors manufactured at the same manufactur- ing plant by mass production methods, in principle, the Society apply to the requirements of this Section for the tests and inspection of air compressors.

2. The air compressors to which the requirements of this Section apply are those used for the starting of diesel engines, controls of machinery and equipment, power sources and general service, and are of the piston type or vane type.

1302. Type tests

1. The type tests are to be carried out on the air compressors random selected one for each type from the production line.

2. The items of the type test are to be, in general, as follows:

(1) Construction instruction

(2) Leakage test and pressure test

(3) Operational performance test

(A) Continuous running test (for one hour)

(B) Performance test

(C) Operational test of safety devices

(4) Overhaul inspection of major components after operational tests

Cylinder head, cylinder, piston, piston pin, connecting rod, crankshaft, bearing (small end and big end bearing, main bearing), crankcase, suction valve, discharge valve, intercooler, after cool- er, attached pump (lubricating oil and cooling water), outlet non-return valve and relief valve

(5) Other tests required by the Society

1303. Tests of individual Air Compressors after approval

Construction instruction, pressure test and performance test of safety devices during operation are to be carried out. In case where noise and/or vibration which is required to be ascertained is occurred, overhaul inspection may be requested by the Society.
