Mechanical refrigeration systems

The 11th edition of CSA B52 provides minimum requirements for the design, construction, installation, inspection, and maintenance of mechanical refrigeration systems. It contains recommendations and best practices and is not considered law until it is adopted by a jurisdiction. The standard applies to all refrigeration systems installed, whether in new or existing premises, to systems that undergo a substitution of refrigerant, and to parts that are replaced in or added to the system.†With numerous updates and changes, this edition of the Code contributes significantly to further minimizing the risk of personal injury.
