Fitting CRN Numbers
For reasons that can no longer be remembered, fittings must be registered in individual categories. Unfortunately this increases registration cost and paperwork for companies with products that span more than 1 category. Per CSA B51-14 4.2.2:
Each category of fitting manufactured (see Table 1) shall be separately registered by the manufacturer with the regulatory authority…
CSA B51-14 Table 1: Categories of Fittings Category Type of Fitting A Pipe fittings, including couplings, tees, elbows, wyes, plugs, unions, pipe caps, and reducers B All flanges C All line valves D All types of expansion joints, flexible connections, and hose assemblies E Strainers, filters, separators, and steam traps F Measuring devices, including pressure gauges, level gauges, sight glasses, levels, and pressure transmitters G Certified capacity-rated pressure relief devices acceptable as primary overpressure protection on boilers, pressure vessels and pressure piping, and fusible plugs H Pressure-retaining components that do not fall into Categories A to G Note: Categories A, B, C and G fittings are exempt in Saskatchewan. Standard A, B, C and G fittings are exempt in B.C.*
*For B.C., a standard fitting is one that is listed in the B31.1, B31.3 and B31.5 standards. Per BCSA Directive NO: D-BP-2013-03
Nonstandard or unlisted piping components not complying with the specifications and standards listed the ASME B31 Code for Pressure Piping or pressure relief devices not in compliance with the requirements of the ASME Boiler and Pressure Vessel Code, shall be registered in accordance with Section 84(2) by submitting the documentation specified in CSA B51 section 4.2.6(b).
Some typical fitting registration numbers:
0A5983.1 Category A piping fitting issued by BCSA. 0B09081.234567890YTN Category B flange registration issued by ABSA. Registration was not required or not available in B.C. Registration is no longer required in Saskatchewan, but was requried at the time of registration. 0B09081.2CL Same fitting, accepted Canada Wide abbreviation because BC is not required, note TSASK has been issued but is no longer required and could be dropped at the time of renewal. The “CL” designation indicates that the number has been issued everywhere it is required. 0C07555.2C Category C valve fitting, first issued by ABSA, registered Canada Wide. This fitting no longer needs registration in Saskatchewan. Registration in B.C. is currently still required because the design is not listed in the B31 piping codes. If registered today it would be 0C07555.2CL 0H10655.5ADD1 Addenda of an Ontario CRN, first issued by Ontario. See addends below. R0292.51467890YTN FITG A category “H” fitting that must be registered as a vessel, like a dental autoclave, which is too small to be a vessel but must be registered as a vessel regardless – or – a category “H” item which contains both vessel and fittings (a line of products that starts off fitting size but becomes vessel as a dimension like length changes).
FITG can also indicate an item that was first registered as a pressure vessel in a province other than Ontario, but is defined as a fitting in Ontario. Usually there is no statutory declaration.
Fitting registrations expire 10 years after issuing. An addendum updates some details of an application, but the clock is not reset. For example, a CRN addended 5 years after issue will still expire after 5 more years (or 10 years after the original registration date).
0C12887.5C A valve registration issued by Ontario, accepted Canada wide. 0C12887.5CADD1 One year later, the scope of registration has been expanded and accepted Canada wide. Additional valves or configurations have been added to the scope of registration, but the original registration has not been reviewed to save time and cost. The expiration date remains the original date. The latest code in effect at the time of addenda is used to cover the addenda. 0C12887.5CADD2 Again, the CRN has been addended, and again only the additional scope has been reviewed by the jurisdictions. The expiry date remains that of the first registration. Again, the latest code in effect at the time of addenda is used to cover the addenda.
A revision requires the examination of the complete file against the current code edition, (not the edition in effect for the date of original submission). The revision process must start at the first province to maintain the original number and then repeated with all other provinces also registered in. Once complete, the revision extends the expiry clock to 10 full years from the date of revision.
0A5609.5 CRN issued by Ontario for a standard category A fitting (pipe fittings, including couplings, tees, elbows, wyes, plugs, unions, pipe caps, and reducers). The registration expires in Ontario 10 years after the date of issue. OA05609.52467890YTN The CRN after all jurisdictions have accepted it. The registration expires everywhere on the Ontario expiry date. This standard category A fitting does not require registration in B.C. or Saskatchewan (“1” and “3” are missing from the number). OA05609.5CL A convenient short form indicating that the fitting has been registered everywhere it is mandatory. The shortform is created by the customer, not the jurisdictions (unless the Canada wide registration is done by a jurisdiction). 0A5609.5R1 The CRN has been revised with Ontario, the first province of registration. The CRN now expires in Ontario 10 years after the revised CRN date. 0A5609.52 Alberta has accepted the revised CRN, Alberta does not include revisions or addends in the CRN number. The fitting can be used for new designs in Alberta until the Ontario expiry date. OA05609.52467890YTNR1 The revised CRN has been accepted by the remaining jurisdictions. The CRN is now acceptable everywhere until the new Ontario expiry date. OA05609.5CLR1 Again the convenient short form indicating that the revised fitting has been registered everywhere it is mandatory. The R1 notification that was not included in the Alberta registration will be ignored if it is used in Alberta submissions.
A renewal is required after the fitting registration expires on its 10th anniversary if it will still be sold into new piping systems or installed on a new vessel. Only fittings expire, not pressure vessels or piping systems. The end user must keep the piping system or vessel according to the original registration. Changes in fittings used will require revised registration. The expiry prohibits the use of the fitting in new registered vessels or piping systems, it does not mean that the existing fittings currently in use have to be removed from service.
In theory the renewal is now easier according to CSA B51-14 4.2.8(c):
for the resubmission for validation required by Clause 4.2.1 (provided that the documentation specified in Item (a) or (b) was provided to and evaluated by the regulatory authority and is still applicable, and that Clauses 4.1.2 and 4.1.4 do not apply): (i) a properly completed statutory declaration form for the registration of fittings; (ii) a copy of the manufacturer’s valid quality control program certificate; and (iii) the scope of product registration within the original registration.
This is much simpler than original submissions, and cannot include items that were not in the original submission, but does this work? In practice this varies. Some reviewers accept renewals within the same scope with just items (i), (ii) and (iii) and do a quick registration at low cost. However some reviewers require a full re-submission of all documents originally submitted and go through a complete technical review. We do not know which reviewer we will get at time of renewal so we start with submitting items (i), (ii) and (iii) as required by the standard, and which often works, and supply more materials as required. Obviously the cost varies considerably by reviewer.
0B8237.5 A flange CRN issued by Ontario. 0B8237.5R1 The CRN has been renewed by Ontario and is valid for another 10 years from the renewal date. The R1 nomenclature is identical to that used on a revision and in both cases is good for another 10 years.
CSA grants CRNs, but they are only acceptable in Quebec and Saskatchewan.
CSA-0F10904.56 A measuring device CRN issued by CSA. CSA subcontracted the review to Ontario which issued a number 0F10904.5. CSA added the Quebec designation. Because this is a CSA CRN, it is also valid in Saskatchewan even though it is not include in the CRN number. 0F10904.5 The CRN as it was issued by TSSA to when contracted to review the job by CSA.
In this case CSA used Ontario’s review as the basis of their Quebec registration. This is the remnants of what was to become a Canada wide fitting registration system. This attempt failed, but as of 2015 rumours of another attempt at creating a one stop Canada wide registration system based in CSA are circulating once again.
A fitting is not required to be registered in Saskatchewan pursuant to The Boiler and Pressure Vessel Act if:
It is registered by CSA;
It is a category A, B, C, or G fitting, as set out in the CSA B51 code
From BCSA D-BP 2013-03 for more information.
Exemption of Category A, B, C, and G fittings from registration.
The exemption of fittings from registration shall apply only to piping components complying with the standards and specifications listed in the ASME B31 Pressure Piping Codes and to certified pressure relief devices complying with the requirements of the ASME Boiler and Pressure Vessel Codes.
Non-standard or unlisted piping components not complying with the specifications and standards listed the ASME B31 Code for Pressure Piping or pressure relief devices not in compliance with the requirements of the ASME Boiler and Pressure Vessel Code, shall be registered in accordance with Section 84(2) by submitting the documentation specified in CSA B51 section 4.2.6(b).
CSA-0F16276.56 A fitting registered in Ontario, then in Quebec through CSA. Saskatchewan use is also allowed because the CSA registration from Quebec (the only other province allowing CSA).
