A Canadian Registration Number (CRN) for a boiler or pressure vessel is defined by CSA B51 Clause 4.3 as:
consisting of a letter, four digits, and a decimal point followed by up to ten digits and/or two letters
the first letter and four digits are part of a sequential numbering system used by the issuing province or territory
the first digit or letter to the right of the decimal point indicates the province that issued the particular number
the following identifications are used in accordance with the code:
1 - British Columbia
2 - Alberta
3 - Saskatchewan
4 - Manitoba
5 - Ontario
6 - Quebec
7 - New Brunswick
8 - Nova Scotia
9 - Prince Edward Island
0 (zero) - Newfoundland
T - Northwest Territories
Y - Yukon Territory
N - Nunavutthe letter C may follow the designation of first registration if a design is registered in all jurisdictions. No jurisdiction issues the letter C; it is a convenience for stamping once the manufacturer has received all the registrations.
to be eligible for use in Alberta, the CRN must have the digit 2, or the letter C, somewhere after the decimal point.
CE Marking
For selling to and within EU countries, it has become increasingly important to have CE certification and marking. For our industry of metering pump accessories, Pressure Equipment Directive (PED) 97/23/EC is applicable.
The majority of our products are classified as SEP (Sound Engineering Practice). This classification means that our products do not require CE marking or certification in order to be used within the EU.
