Temp. column of Table A ASME B31.3 VS B31.1: Do they have the same CRN Some would say that if a fitting has a CRN registration, what does it matter if its registered to a different code of construction than another? After all, a CRN registration is a registration is a registration. This response would seem to be in line with the idea that, when considered in their entirety, both codes are equal. But when considering CRN (Canadian Registration Number) requirements, this idea is incorrect in many ways.
