(b) in the case of copper pipes or steel pipes, be to the appropriate hydraulic test pressure specified in a recognized engineering standard or code. (Amended 87 of 1988 s. 30)

Appointed examiner examining boiler, etc, under maximum permissible working pressure to set safety valve

45. Whenever, for the purposes of this Ordinance, an appointed examiner is carrying out an examination of a boiler, steam receiver or air receiver under the pressure that will be specified in the certificate of fitness as its maximum permissible working pressure, he shall, by sealing or some other suitable method, ensure that the safety valve is so adjusted as to prevent the boiler, steam receiver or air receiver, as the case may be, from being operated at a pressure greater than that pressure.

PART VI

INITIAL DETERMINATION OF MAXIMUM PERMISSIBLE WORKING PRESSURE OF BOILERS AND PRESSURE VESSELS

(Amended 87 of 1988 s. 34)

Initial determination of maximum permissible working pressure of boilers and pressure vessels

47. (1) Where a new boiler or pressure vessel is being examined for the purposes of section 24, an appointed examiner shall determine the maximum permissible working pressure at which, in his opinion, the boiler or pressure vessel, as the case may be, may be operated. (Replaced 67 of 1978 s. 23)

(2) Where, in accordance with the provisions of subsection (1), the maximum permissible working pressure of a boiler or pressure vessel has been determined, the appointed examiner who determined the same shall notify the Authority thereof.

(3) The following provisions apply in relation to the determination under subsection (1) of the maximum permissible working pressure of a boiler or pressure vessel, namely-

(a) where, in the opinion of the appointed examiner who is determining such pressure, it is necessary for him, in determining the same, to assess such pressure by calculation, the calculation shall be based on the formulae specified in a recognized engineering standard or code relating to boilers or pressure vessels, as the case may be, of the type or class in question, or, where, in relation to boilers or pressure vessels of the type or class in question, no formulae are so specified, on such formulae as the Authority specifies; (Amended 87 of 1988 ss. 30 & 34)

(b) where the maximum permissible working pressure of a boiler or pressure vessel of unknown or uncertain origin or history has been assessed by calculation, the maximum permissible working pressure of the boiler or pressure vessel, when determined by the appointed examiner, shall not be greater than the pressure so assessed less 10%; and
