Allowable Stress - 01/19/19 05:02 PM

Hello Stressers,

Just curious on the Allowable Stress in ASME B31.3 related to creep. I'm curious to know if the allowable stress say due to rupture or strain, was based from what certain time of creep test extrapolated to 100,000 hrs?

Please correct if my statement is wrong.

Many Thanks,

B31.3 sets the elevated temperature allowable stress criteria in 302.3.2(d),(e) & (f).
