Boiler and Pressure Vessel Code

NB Reg 84-174, Last updated April 15 2011

101 This Regulation applies to boilers, pressure vessels, heat exchangers, air receivers, liquid receivers, oil refineries, refrigeration plants, power plants, steam processors or any other pressure vessel, fitting or piping.

110 All piping used in connection with boilers and pressure vessels shall meet the requirements of the ASME Boiler and Pressure Vessel Code or, where such requirements are not applicable, the requirements of the applicable ANSI standards prescribed in the Standards Regulation – Boiler and Pressure Vessel Act. [84-177]

“expansible fluid” means (a) any vapour or gaseous substance, or (b) any liquid under a pressure and at a temperature that is such that the liquid will change to a gas or vapour when the pressure is reduced to atmospheric pressure;

“fittings” means safety valves, stop valves, automatic stop-and-check valves, blow-down valves, reducing valves, water gauges, gauge cocks, pressure gauges, injectors, test cocks, fusible plugs, regulating and controlling devices and pipe fittings or any other apparatus or component attached to or forming part of any boiler, pressure vessel, plant or oil refinery;

“pressure piping system” means pipes, tubes, conduits, fittings, gaskets, bolting and other components making up a system, the sole purpose of which is the conveyance of an expansible fluid under pressure and the control of the flow of an expansible fluid under pressure between two or more points;

CHANGES REQUIRE REGISTRATION 310 (3) A change in material, thickness, diameter or design pressure shall constitute a new design.

Heating Plants and Power Plants Regulation

B Reg 84-175, Last updated April 15 2011

“high pressure heating plant” means a boiler or two or more boilers on the same premises having a safety valve setting of more than fifteen pounds per square inch (one hundred and three kilopascals) when the boiler is used for producing steam, or a safety valve setting of more than one hundred and sixty pounds per square inch (one thousand one hundred kilopascals) when the boiler is used for producing hot water or when the temperature of the hot water produced is in excess of two hundred and fifty degrees Fahrenheit (one hundred and twenty degrees Celsius);

“low pressure heating plant” means a boiler or two or more boilers on the same premises having a safety valve setting of not more than fifteen pounds per square inch (one hundred and three kilopascals) when the boiler is used for producing steam, or a safety valve setting of not more than one hundred and sixty pounds per square inch (one thousand one hundred kilopascals) when the boiler is used for producing hot water at a temperature of not more than two hundred and fifty degrees Fahrenheit (one hundred and twenty degrees Celsius);

“therm-hour” means one hundred thousand British Thermal Units per hour;(thermie/heure)

3 The Act does not apply to: (a) heating and power plants under the jurisdiction of the Canadian Transport Commission; (b) low pressure heating plants having a rating of fifty therm-hour or less; and (c) high pressure heating plants having a rating of twenty therm-hour or less.

Propane, Natural and Medical Gas Regulation

NB Reg 84-176, Last updated April 15 2011

“gas” means natural or propane gas;

“medical gas” means oxygen, nitrous oxide, medical air, medical vacuum, nitrogen, carbon dioxide, helium and any mixtures thereof;

3 This Regulation applies to (a) the manufacture, storage, transportation, handling, installing, testing and inspecting of gas and medical gas and of the associated appliances and equipment for the utilization of gas, (b) the maintenance of appliances and equipment for the utilization of gas, and (c) the installing, testing and inspecting of gas and medical gas piping systems.

6 Piping used in connection with this Regulation shall meet the requirements of the applicable ANSI standards and CSA standards prescribed in the Standards Regulation – Boiler and Pressure Vessel Act. [84-177]

7 The Chief Inspector may accept as approved (a) gas and medical gas appliances and equipment tested and listed by: (i) the Canadian Standards Association; (ii) the Canadian Gas Association; (iii) the Underwriters Laboratories of Canada; (iv)Factory Mutual; or (v) a laboratory not listed in subparagraphs (i) to (iv) that is acceptable to the Chief Inspector; and (b) fittings tested and listed by the Underwriters Laboratories Incorporated or any other laboratory acceptable to the Chief Inspector.

PROPANE AND NATURAL GAS PLANS AND SPECIFICATIONS 20(1) Plans and specifications, in triplicate, of the design of gas systems that are independent of other mechanical systems and of the design of any alteration or addition thereto shall be submitted to the Chief Inspector to determine whether this Regulation has been complied with before any work commences on or any alteration or addition is made to (a) Repealed: (b) filling plants, (c)dispensing units, and (d) all gas installations having a total heating value of five million British Thermal Units or greater.
