ASME B31.1-2004/2007
ASME B31.1-2004/2007
(OP)
Hello all,
I was checking the ASME B31.1-2004 and ASME B31.1-2007 and I noticed that the maximum allowable stress values in tension (table A-1) have changed from 2004 to 2007. Did you know that? Why has it changed? Materials have physical properties fixed
Thank you very much,
Regards,
Rocio

RE: ASME B31.1-2004/2007
The reason is the basis of calculating the allowable stress is different for the twom editions of the Codes. Look at the section on determination of allowable stress.

Second, LOOK at the summary of changes in ASME B31.1/2007 Edition on page xiii, there is no mention of any change to Table A-1, there is for Table A-3.
