[CAP. 56

31

(2) Upon receipt of a notification under subsection (1), the Authority may

(a) require the whole of the lagging surrounding the pipe to be removed in

order to enable a thorough examination of the pipe to be made; and

(b) by notice in writing served on the owner of the boiler, steam receiver or steam container for which or in connection with which the pipe is provided, require him to cause the pipe to be subjected by a boiler inspector to an hydraulic test.

(3) An hydraulic test carried out pursuant to a requirement of the Authority made under subsection (2)(b) shall be to-

(a) twice the pressure that will be specified in the certificate of fitness as the maximum permissible working pressure of the boiler or steam receiver for which or in connection with which the pipe is provided; or

(b) the appropriate hydraulic test pressure specified in a recognized

engineering standard or code. (Amended 87 of 1988 s. 30)

(Amended 87 of 1988 s. 35)

Pressure accumulation tests

43. (1) Every pressure accumulation test to which a boiler is subjected for the purposes of this Ordinance shall be carried out-

(a) under full firing conditions;

(b) with the feed water shut off; and

(c) with the stop valves closed except to the extent that it is necessary for any stop valve to be open to supply steam to auxiliary equipment for the purposes of the test. (Added 67 of 1978 s. 20)

(2) Every pressure accumulation test to which a steam receiver is subjected for the purposes of this Ordinance shall be carried out at the maximum pressure of steam supply to which, with the stop valve or valves fully opened and any other plant or equipment that normally receives a supply of steam from the pipe or pipes supplying the steam receiver shut down, the steam receiver may be subjected when the boiler to which it is connected is being operated at the pressure that is or will be specified in the certificate of fitness issued in respect thereof as its maximum permissible working pressure.

(3) Every pressure accumulation test to which an air receiver is subjected for the purposes of this Ordinance shall be carried out-

(a) at the maximum pressure that can be obtained in the compressor to

which the air receiver is connected;

(b) with the reducing valve or valves, or such other appliance as may be used to regulate the supply of compressed air to the air receiver, fully opened; and

(c) with any other plant or equipment that normally receives a supply of

air from the pipe or pipes supplying the air receiver shut down.
