Frequently Asked Questions - Canadian Standards Association (CSA) B51 and Design Registration

Yes this is correct, the legislation refers directly to ASME B31.3 as an acceptable design code (not CSA B51), therefore design registration is not required for process pressure piping and fittings. In cases where CSA B51 is the design standard, design registration is required. A proponent may still choose to register for CRNs in any circumstance and can do this through Technical Safety BC.

There is no requirement to submit these packages to Technical Safety BC, except in instances where there is a design requirement to follow CSA B51. Proponents may still choose to register for Canadian Registration Numbers (CRN) for any reason and can do this through Technical Safety BC.

Prior to start-up following installation of the piping, the permit holder must have all this information available. The signed and sealed P&IDs must be submitted to the Commission following installation of the piping. The Commission may choose to audit the rest of the documentation.

If a design is currently registered, it is up to the permit holder whether to maintain the registration or cancel it. If they choose to keep it registered, design registrations for Commission-regulated elements will be reviewed and administered by Technical Safety BC. In these cases, compliance with the design registration requirements will fall to the Commission. This would be in addition to the Commission requirements.
