This is an extract of information collected from the following source: Boiler and Pressure Equipment Regulations O.I.C. 2011-27 (January 18, 2011, effective April 1, 2011), N.S. Reg. 10/2011

Definitions

“BPE standards” means the standards for boilers and pressure equipment established or adopted by the Minister in the Technical Safety Standards Regulations made under the Act;

“diameter”, in relation to a regulated product, means the inside diameter of a pressure boundary, unless otherwise stated in the BPE standards;

“expansible fluid” means either of the following: (i) a vapour or gaseous substance, (ii) a substance that is a liquid under its current pressure and temperature but that will change to a gas or vapour when the pressure is reduced to atmospheric pressure;

“gas” means any of the following: (i) natural gas, either before or after processing, (ii) a substance recovered from natural gas, crude oil, oil sands or coal for transmission in a gaseous state; (iii) a gaseous substance used to inject through a well into an underground formation;

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

“pressure plant” means a plant with an installation of a boiler, pressure vessel, refrigeration system or compressed gas system that is operated either alone or in combination as a unit by the same owner and management, whether the unit is portable or permanently attached to a solid base, and includes any compressor, piping, appliance or equipment attached [to] or used in connection with the plant;

“process plant” means a commercial or industrial facility where fluids, gases or solids are processed using pressure and temperature to help generate a manufactured regulated product;

Exemptions

Products exempted from Act and regulations 4 (1) All of the following products are exempt under subsection 6(2) of the Act from the Act and these regulations:

(j)a pressure piping system with any of the following types of piping or tubing:

(i)piping that is part of a system that is operating at a temperature of 121 degC (250 degF) or lower, and has (A) a steam service with [a] system safety or relief valve set at a pressure of 103 kPag (15 psig) or lower, or (B) a water service with [a] system safety or relief valve set at a pressure of 1103 kPag (160 psig) or lower,
(ii) piping or tubing with [a] system safety or relief valve set at a pressure of 690 kPag (100 psig) or lower and a temperature between -29 degC (-20 degF) and 121 degC (250 degF), and the system is used to deliver treated or non-treated domestic water, products for human consumption, glycols, or non-toxic and non-lethal substances that are considered chemically and environmentally benign,
(iii) air piping or tubing that has a system safety or relief valve set at a pressure of 1379 kPag (200 psig) or lower,
(iv) piping or tubing that is part of a breathing air system that is modularized, manufactured and has a certification mark of a recognized certification organization,
(v) piping or tubing used directly in (A) pneumatically or hydraulically controlled instruments, or (B) steam tracing,
(vi) refrigeration piping or tubing of a refrigeration system that has a maximum output capacity of 11 kW or less, or air conditioning used for human comfort,
(vii) piping or tubing used for the delivery of fuels directly into a combustion system and subject to the Fuel Safety Regulations made under the Act,
(viii) piping or tubing in a piping system used for fire suppression that is subject to the Fire Safety Act,
(ix) piping or tubing used to deliver medical and inert gases,
(x) threaded piping of nominal diameter 50 mm (DN50) or 60.33 mm in outside diameter (nominal pipe size 2 in. (NPS 2) or 2.375 in. in outside diameter) or less with a system safety or relief valve set at a pressure of 1034 kPag (150 psig) or lower if it either (A) meets the BPE standards, or (B) is a pressure piping system that meets the requirements of the industry standard for the particular pressure piping system as determined by the BPE chief inspector;
