Which document serves as the primary reference for pressure equipment regulation?

The primary reference for pressure equipment regulation in Canada is indeed CSA B-51. This standard outlines the requirements for the design, fabrication, inspection, testing, and certification of pressure vessels and systems. It plays a crucial role in ensuring safety and compliance within the pressure equipment sector by providing guidelines that manufacturers and inspectors must follow.

CSA B-51 is specifically focused on pressure vessels, so it is tailored to address the various concerns related to this type of equipment, including material selection, construction processes, and safety considerations. This makes it a cornerstone document for anyone involved in the design, installation, or maintenance of pressure equipment.

While CSA B-52 relates to mechanical refrigeration and includes aspects of refrigeration systems, it does not serve as the primary reference for all pressure equipment. ASME standards, such as Sections I and IV, pertain to different aspects and applications; Section I covers power boilers while Section IV deals with heating boilers. Therefore, although they are relevant in their respective areas, they do not hold the same general regulatory authority over pressure equipment as CSA B-51.
