CRN means Canadian Registration Number.
The requirement for such is enshrined in the boiler and pressure vessel laws of each province and territory. It is used in the enforcement of public safety regulations to the extent that units cannot be placed in operation until there is a CRN issued for the design. In the same manner the authorized person under the law has the authority to cancel or suspend the CRN where there is a danger to public safety. A complete description can be found in the CSA B 51 Boiler Pressure Vessel and Pressure Piping Code.

In the case where a CRN is required for all of Canada an application is made to one jurisdiction to have the CRN established. If this was started in New Brunswick for example a CRN could look like this,1234.7. Once a CRN has been issued for a design then applications are made to all other jurisdictions simultaneously. As the design goes through the registration process each province adds their identifying digit to that CRN. A design registered in all of Canada then would have a CRN which looks like this;1234.7890YTN123456. The manufacturer can shorten that number to 1234.7C once they have possession of the registration documents from all 13 jurisdictions. In summation, the base CRN as issued,1234.7 is accepted by all jurisdictions however their identifying digit can only be added in accordance with their own regulations and by the authorised person under those regulations. Simply put a law enacted by the New Brunswick legislature has no authority outside of New Brunswick.

Under the constitution which united the 13 jurisdictions of Canada, public safety within their own boundaries is the responsibility of that jurisdiction. The federal government has no authority to intercede or to make laws governing that process.

To register a boiler or pressure vessel design in all 7 ACI Central jurisdictions the cost is approximately $1500.00
To register in all of Canada will range from $3800 to $5000 due to the fact that other provinces have variable hourly rates with no limit on the time spent for a review. Note that this is an approximation and is subject to change.

Depending on where the client wants to start it will take from 3 to 12 weeks to have a CRN established. If the registration is for all of Canada then we recommend aiming for the 3 week time frame and continuing on from there. The process will still take up to 12 weeks to complete from the time the CRN is established.

In the case of a boiler or pressure vessel design the CRN does not expire unless there is a change in the ASME code that would make the design unsafe. In the case of a a fitting registration the CRN is valid for 10 years .

Fittings are defined as appurtenances attached to pressure equipment and are defined by category;
A- pipe fittings such as elbows, tees, plugs etc.,
B- pipe flanges,
C- valves of all types,
D- expansion joints, flexible connections, hoses.
E-strainers, filters, separators, steam traps.
F- measuring devices including pressure gauges, lever gauges, sight glasses, level and pressure transmitters.
G-capacity certified pressure relief devices acceptable as primary pressure relief devices on boiler , pressure vessels
And pressure piping and fusible plugs.
H- pressure retaining components which do not fall into categories A to G
Note: each category requires a CRN.
