A Practical Handbook for Implementing CSA B52, Mechanical Refrigeration Code
1 Scope of CSA B52
The scope of CSA B52 is to provide minimum requirements for the design, construction, installation, and maintenance of all mechanical refrigeration systems, as provided for by provincial and territorial acts, to minimize the risk of human injury.
The Code applies to all refrigeration systems installed subsequent to its jurisdictional adoption, whether in new or existing premises, to systems that undergo a substitution of refrigerant, and to parts of a refrigeration system that are replaced in, or added to, refrigeration systems installed prior to its adoption.
The word "adoption" refers to the date a jurisdiction adopts the Code, and so not necessarily to the year in which the Code was published.
