Curtis,
I did some research and yes, you're right: Saskatchewan, B.C., and Manitoba would exempt our check valves (ASME B16.34 & API-598).
However, we have approval in these provinces - for sales, it's a lot easier to have a CRN on file than to explain "no, we don't need it, and here's why..." followed by a discussion, emails, etc. And then in the end, if the customer specification states "CRN required", that trumps any argument. It looks like the first approval of our check valves was, in fact, Saskatchewan at a customer request.
Looking through the files, this was a long process - 2009 when numbers were first issued, 2011 by time they had all provinces. I think we may begin working on it soon. I emailed ACI Central (and Alberta, but no response), regarding renewals - it's the same as a new application. And if we want the same CRN Number to be issued, we'll have to apply to the original province of first approval who issued the CRN, then work through the other provinces after it is re-secured. Otherwise, we'll end up with new numbers. It may not be that important - I was just thinking that consistency is good.
Geof.
Geof,
I heard that Quebec also wanted to join to the group to exempt fittings, flanges, valves made to ASME listed standards. I'm not sure what is situation.
I my opinion, CSA B51 committee should consider exemption of standard flanges, valves, and fittings which are built to ASME listed standards. There is no point in having registered, for example, a standard B16.5 flange. In fact, every manufacturer who wants to sell them in Canada should have CRN, if its not exempt from registration by provincial authority.
Thanks,
Curtis
