Mechanical refrigeration code as amended from time to time, is hereby adopted with the following exceptions, additions or positions on requirements in the following referenced clauses from the Standard: NOTE: Reference Clauses as given in CSA B52. Post instructions in frame with glass cover in accordance with CSA B52. IIAR Standards Proponents shall prepare designs based on the facility being interpreted with an importance factor “Normal” as per NBCC Table 4.1.2.1.

CSA B51 – Pressure Vessel & Piping Code.

CSA B52 – Mechanical Refrigeration Code.

2.Ĭodes and Standards The facility will be designed in accordance with good engineering practice, and the latest applicable provincial and local code requirements, including: Soldered joints are not permitted for new construction or repairs of refrigeration pressure pipingsystems subject to the requirements of the CSA B52 Mechanical Refrigeration Piping Code.Īnnealed copper: to ASTM B280, with minimum wall thickness as per CSA B52 and ASME B31.5. This Standard applies to refrigerant-containing components that are intended to be used in field- installed refrigerating and/or air-conditioning systems in accordance with CSA B52 and that are charged with the refrigerant identified for use in the components.

Leak test to CSA B52 before evacuation to 2MPa and 1MPa on high and low sides respectively. He added that the prioritization of CADs is critical to shifting away from the current method, and explained that the prioritized CAD amendments are the BPV (CSA B51 Pressure Piping Code) and ( CSA B52 Mechanical Refrigeration) and in Fuels the CSA Z662 Oil and gas pipeline code.
