B31.1 what is current addenda

[PVinspector]

Is the B31.1 2004 with 2005 Addenda the most current (mandatory) or is there a 2006 Addenda? I know the 2007 is not due out until early next year.

Thanks.

The 2006 addenda has been issued last December 15, 2006. It is mandatory as of June 15, 2007.

the B31.1 2004
B31.1 is issued under different editions and addendas,
that do not match other sections of the Code,
I would call the ASME to be sure.

 

[CodeRef]

If "Boiler External Piping",which is under ASME Section I, see Table A-360 for the appropriate Edition/Addenda of ASME B31.1.
If "NonBoiler External Piping", then utilize the current edition of B31.1.
As always, check with the Jurisdiction of installation for additional requirements/limitations.
