What is a CRN?
A CRN (Canadian Registration Number) is a unique number issued by a Canadian provincial or territorial safety authority that confirms the design of a pressure-retaining item (a vessel, boiler, heat exchanger, fitting, valve or piping system) has been reviewed and accepted for use in that jurisdiction. It is legally required before the equipment can be installed or operated in Canada.
Why does a CRN exist?
Canadian provinces regulate pressure equipment for public safety under legislation that adopts the CSA B51 standard. Before any pressure equipment operates, its design must be registered so the authority knows it meets recognized construction codes (typically the ASME Boiler & Pressure Vessel Code). The CRN is the proof of that registration.
CRN vs ASME U Stamp: what is the difference?
An ASME Code stamp (such as the U Stamp for vessels) certifies that the item was fabricated under an approved quality program. A CRN registers the design with a Canadian authority. They are complementary: the ASME Code stamp helps your case, but it does not replace the CRN. To sell into Canada you generally need the design registered (CRN), and often the fabrication certified (ASME) as well.
How an Indian manufacturer gets a CRN
- Identify the Canadian province(s) where the equipment will operate.
- Prepare a design package: drawings, design data, calculations, QC certificate.
- Have the calculations reviewed and the package authenticated by a Canadian-licensed P.Eng.
- Submit to the provincial authority (TSSA, ABSA, Technical Safety BC, RBQ, TSASK, ACI).
- Address review comments until the CRN is issued.
