Introduction, Page3, Paragraph 4.
Delete existing paragraph and replace with :-
“Small boilers (i.e. boilers with a capacity of not more than 3 bar-litres are exempted from the requirements of this code. However, it is recommended that small boilers be fitted with at least a safety valve and a pressure gauge and that these be tested every 12 months in order to ensure correct operation at the correct release pressure. The boiler and the pipe work installation should also be checked at least every 12 months.”
Page 11, Section 10. Steam Test.
Delete all the sub-sections and replace with:-
10.1 An examination under steam pressure shall be undertaken, a) before first placing the boiler into service, b) after every hydraulic test, and c) at intervals not exceeding 14 months.
10.2 The boiler shall be steamed and further examinations carried out as pressure is rising and whilst the boiler is at working pressure.
10.3 Correct operation of the following items should be verified :-
Boiler water feeding arrangements by at least two independent means (hand pump, injectors, mechanical pump, etc)
Pressure Gauge.
The Water Gauge(s) should be blown down and the water should be seen to recover to its level without delay.
10.4 On boilers of less than 10 bar-litre capacity with a total internal volume not exceeding two litres it is acknowledged that the provision of two independent means of water feed arrangement may not be possible. Therefore for the purpose of testing these boilers :-
a) One (1) means of water feed arrangement is acceptable.
b) Water in the Gauge Glass must recover its level without delay following movement of the boiler. Water Gauges fitted to boats whose boilers fall within this size category do not have to be capable of being blown down.
c) The water gauge and pressure gauge should be clearly visible.
10.5 The Boiler should then be steamed at maximum firing rate and with full blower operation. The test shall be continued for sufficient time as to allow the Inspector to be satisfied that stable conditions have been attained. The operation of the safety valves shall be checked to ensure that they operate at working pressure and that pressure does not rise by more than 10% of the working pressure during safety valve operation.
