B-1.1, r. 6.1 - Regulation respecting pressure installations

Full text
3. This Regulation does not apply to the following pressure equipment nor to the accessories and piping connected to it:
(1)  a boiler:
(a)  of the high pressure kind, whose heating surface is 1 m2 or less or whose power is 10 kW or less;
(b)  of the steam, hot water or thermal fluid low-pressure kind, whose wet heating surface is 3 m2 or less or whose power is 30 kW or less;
(c)  whose pressure is 103 kPa or less, open circuit, and that has no valve between the boiler and the vent leading directly to the atmosphere;
(d)  of the hot water kind, whose power is 60 kW or less, whose water temperature is 99 °C or less and whose pressure is 1,100 kPa or less;
(e)  of the hot water or steam kind, that has the following characteristics:
i.  it has no steam drum or steam header;
ii.  the tubes and coils are not used to produce steam;
iii.  it is provided with manually operated nozzles or sprinklers that conduct the fluid directly into the atmosphere;
iv.  the tubes have an outside diameter not exceeding 25 mm and the pipes have a nominal diameter not exceeding 19 mm;
v.  its water volume does not exceed 23 litres;
vi.  it is provided with a temperature control device that prevents the water temperature from exceeding 180 °C;
vii.  it is provided with an overpressure safety relief device adjusted to and sealed at a pressure not exceeding the design pressure indicated on the boiler;
(2)  a water heater whose diameter is 610 mm or less and whose power is 120 kW or less;
(3)  a hot water tank whose diameter is 610 mm or less;
(4)  a hot water tank that is not provided with a power source and that contains water at a temperature of 99 °C or less;
(5)  a pressure vessel used as the enclosure for gas pressurized electric equipment and for any tank forming part thereof;
(6)  a hydropneumatic tank whose diameter is 610 mm or less, whose volume is 450 litres or less and whose temperature is 65 °C or less;
(7)  an expansion tank whose diameter is 610 mm or less and whose pressure is 205 kPa or less;
(8)  a mobile pressure vessel not forming part of a pressure installation and used to transport gas or liquid under pressure or used for the propulsion or operation of a vehicle, a vehicle component or equipment thereof;
(9)  pressure equipment whose primary design data and primary constraints come from the equipment’s operating conditions such as a pump, a compressor, a turbine, an engine or a hydraulic cylinder;
(10)  well control pressure equipment used in the petroleum, gas or geothermal prospection and exploitation industry and in the underground storage and intended to contain or control the well’s pressure;
(11)  pressure equipment used for research and experimentation purposes in a research or teaching establishment;
(12)  a pressure vessel not provided with a direct power source and containing an incompressible liquid whose vapour pressure is 205 kPa or less in absolute pressure at the maximum operating temperature.
This Regulation does not apply to a refrigeration system whose drive motor has a maximum rated power of 125 kW, that is tested and certified by an approved test laboratory, and that meets all the requirements of CSA B52, Mechanical refrigeration code, published by the CSA Group, hereinafter called “Mechanical Refrigeration Code”.
