Hello:
I am running into an issue with a client who is requesting that the stress calcs be in compliance with the 2006 version of ASME B31.4. The reason behind this is that 49 CFR 195 only references the 2006 version of B31.4. I used CAESAR II 2017 to run the calcs which utilizes the 2016 version of B31.4.

My question is, if stress calculations comply with subsequent versions of B31.4 does that ensure that the stress calculations are in compliance with the 2006 version?
