Codes and Standards Currently In Force

In 2015, government enabled timely code adoption in the Pressure Equipment Safety Regulation. This means new codes and standards editions adopted under the PESR will come into force automatically one year after publication. It also means that the regulation will no longer be updated as new code editions come into force. This page will provide industry with which codes and standards editions are in force.

Currently in Force

The following codes, standards and bodies of rules are currently in force:

(a) the following provisions of the CSA Standard B51 – 14, Boiler, pressure vessel and pressure piping code, published by the CSA Group:

  • Part 1, General requirements for boilers, pressure, vessels, and pressure piping, including informative Annex E Inspection of welds in pressure coils exposed to direct radiant heat;
  • Part 2, High-pressure cylinders for the on-board storage of natural gas and hydrogen as fuels for automotive vehicles;
  • Part 3, Compressed natural gas and hydrogen refuelling station pressure piping systems and ground storage vessels;

(b) CSA Standard B52 – 13, Mechanical refrigeration code, published by the CSA Group;

(c) CSA Standard Z662 – 15, Oil and gas pipeline systems, published by the CSA Group;

(d) ASME Boiler and Pressure Vessel Code – 2017, published by the American Society of Mechanical Engineers, except that Section VIII Rules for Construction of Pressure Vessels, Division 2 – Alternative Rules, Part 5 Design by Analysis Requirements cannot be used to override the requirements stated in other parts of ASME Boiler and Pressure Vessel Code – 2017, Section VIII, Division 2, unless such use meets the terms and conditions set out in a variance issued to the owner of the pressure vessel by the Administrator;

(e) the following sections of the ASME Code for Pressure Piping, B31, published by the American Society of Mechanical Engineers:

(k) API Standard 661-2013, Air-Cooled Heat Exchangers for General Refinery Services (7th edition), published by the American Petroleum Institute;

(l) ISO-16528 Boilers and Pressure Vessels – Part 1, 1st Edition, 2007, published by the International Organization for Standardization, for construction not addressed in the above codes and standards provided the same engineering philosophy, safety margins and administrative requirements in CSA B51 are followed.

Early use of editions not yet declared in force is permitted, unless specifically prohibited by the Administrator.
