Eminence of a Canadian Registration Number (CRN)

by Sanjeev Yadav SEO Consultant

The Canadian rules and regulation require the pressure vessels, boilers, and pressure fittings to mandatorily bear the Canadian Registration Number (CRN) before being employed for any industrial purpose. This CRN acts as a certificate of quality, safety, and authenticity of the equipment. Each and every province in this country demands the issuance of a fresh CRN number. According to the Canadian law, it is mandatory for the manufacturer and importer of any pressure vessel, boiler, pressure fittings, and piping systems to submit the structural drawings, design, specifications, etc. to the Canadian authorities for approval. After analyzing the equipment on all the necessary parameters, the authorities issue a CRN number which substantiates that the equipment is safe to be used for various industrial purposes.

CRN at a Glance

A CRN for a boiler or pressure vessel as defined by CSA B51 Clause 4.3 means consisting of a letter, four digits, and a decimal point followed by up to ten digits and three 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 CRN identifies the design has been accepted and registered for use in that province or territory. The following mentioned table represents the usage of digits or alphabets for different provinces.

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

N = Nunavut

T = Northwest Territories

Y = Yukon Territory

Relevant points for consideration

The drawings, calculations, specifications etc., should be self-attested by the manufacturer of a boiler or pressure vessel or owner of the design and the manufacturer must provide an ASME Certificate.
Any changes in the design if made after the approval will be evaluated again on the basis of crucial parameters. Manual changes to the design tend to get rejected at the time of submission.
The manufacturer can manufacture multiple units under one registered design unless the Code or regulations invalidate the design or restrict the number of units that can be engineered on the basis of approved design.
A fee is surely charged by the Canadian authorities for processing a design. The fees charged by them depends on various factors like the size of the boiler or pressure vessel, the intricacy of the design, the time consumed by the authorities for analyzing the design, and much more. This fee is charged in both the cases i.e. acceptance or rejection of the design.
