Why are CRN Numbers (Canadian Registration Numbers) required?
Canadian Registration Numbers (CRN numbers) identify unique pressure equipment designs for use in Canada, and must meet requirements. Each design concept has a unique number. One Canadian Registration Number can represent millions of individual items, each with a different serial number, that all conform to the CRN design.Canadian provincial regulatory authorities have cooperated to help ensure CRN numbers are tracked nationwide, and identifiable across provincial boundaries. CRN numbers are required to be stamped on equipment or, in the case of very small fittings, trackable with other identification markings.CSA B51, the Canadian “Boiler, Pressure Vessel, and Pressure Piping Code”, describes the required rules of CRN use in detail. Part 1, Clause 4 specifies that pressure fittings, pressure vessels, and boilers are assigned CRN numbers with the acceptance of regulatory authorities in provinces where the equipment is to be used.Vessel and boiler CRN numbers never start with a “0”. Fitting CRN numbers always do. All CRN numbers have a decimal point that follows the prefix assigned by the regulatory authority.For fittings, the letter following the “0” in the prefix corresponds to CSA B51 Table 1, and is used by regulatory authorities at their discretion to categorize the fitting according to type:
Pipe fittings
Flangesline
Valves
Flexible connections
Strainers, filters, separators, traps
Instrumentation
Over pressure protection devices
Items not in categories A to G
Subsequent characters in the prefix that precede the decimal, are sequentially assigned by the regulatory authority. For some fitting categories, five digits follow the letter noted above that precede the decimal. For vessels, an alphanumeric (unless the registration is really old) and four digital characters precede the decimal.Following the decimal, the geographical region in which the design was first registered is identified with a character listed in Clause 4.3.2.:1 British Columbia
2 Alberta
3 Saskatchewan
4 Manitoba
5 Ontario
6 Quebec
7 New Brunswick
8 Nova Scotia
9 Prince Edward Island
O NewfoundlandYYukonThe prefix, decimal, and character after the decimal identifies a unique design. To indicate all of Canada, the letter “C” is subsequently used. To indicate all regions in Canada which require registration, the “CL” is used.Subsequent digits identify other regions in which the design has been registered, in no particular order.Here are some examples of CRN numbers:
B1234.256pressure vessel design initially registered in Alberta, and also registered in Quebec and Ontario
B1234.265same CRN number as noted in 1 above despite reversal of “65”
B1234.465pressure vessel design different from items 1 and 2, and registered first in Manitoba
0B1234.265flange design registered first in Alberta
0B1234.165flange design different from that identified in item 4, and registered first in British Columbia
0B1234.2Cflange design as noted in item 4, but registered in all Canadian regions
0B1234.2CLflange design as noted in item 4 above, but registered in all Canadian regions except those where registration is not required
