It remains to be seen as to the impact that this non-mandatory appendix will have... many factors drove its inception, and COADE does have a participant on this comitee - sub-comittee
But for those people pretending to be competent in the field of piping flexibilty analysis who always gave their ignorance away when analyzing B31.3 piping by asking why CAESAR II didn't give them an operating code stress I guess it will be their lucky day, they will still be ignorant of the code just a bit harder to spot!
