What is Canadian Registration and CRN:
In general, a Canadian registration number (CRN) is a unique number assigned to pressure retaining equipment and systems with a maximum operating pressure of 15 PSIG or more that may require legal registration and approval to install and operate in Canada. The rules and exemptions for obtaining a CRN are defined in CSA B51, the Boiler, Pressure Vessel, and Pressure Piping Code. However, the interpretation of these rules and exemptions may vary depending on the Provincial Regulatory body, so it is crucial to understand the code requirements and Provincial Regulations.
Once the design and specifications of the pressure retaining equipment and systems are accepted and registered by the regulatory authority, they are assigned a CRN. A CRN typically consists of a letter, four digits, and a decimal point, followed by up to ten digits and/or two letters. Designs are registered provisionally, and the CRN indicates that the equipment or system has been approved for use and meets the applicable codes and standards.
The Designs are registered Provisionally and following identifications are in use:
1. British Columbia
2. Alberta
3. Saskatchewan
4. Manitoba
5. Ontario
6. Quebec
7. New Brunswick
8. Nova Scotia
9. Prince Edward Island
0. Newfoundland and Labrador
T. Northwest Territories
Y. Yukon
N. Nunavut
Since 2020, the design reviews conducted by the provinces and territories in Canada for the Canadian registration number (CRN) have become mutually recognized by the jurisdictions participating in the Reconciliation Agreement. This means that once a design is registered and approved in one province, it may be accepted for use in other participating provinces without the need for additional registration. This agreement streamlines the process for obtaining a CRN for pressure retaining equipment and systems and makes it easier for manufacturers and users to obtain the required approvals for their equipment and systems.
It is important to note that while the Reconciliation Agreement has streamlined the CRN registration process, the design must still be registered in the province where it will be used first. The requirements for registration may vary between provinces, so it is essential to understand the applicable regulations and codes in the province where the equipment or system will be used. This ensures that the equipment or system is designed and constructed to the required standards and meets the necessary safety requirements for its intended use.
