Temperature for bend test 1

[IFRs]

At what temperature should WPQ coupons have their tensile, bend, hardness and impact testing performed at? Should it be at the lowest design metal temperature that the procedure is written for?

In short, tensile and bend testing is done at ambient temperature because these properties do not vary substantially with low temperature (in general). The only test that requires variation in temperature is the CVN impact test because it is obvious that one is testing notch toughness behavior at MDMT.

Forgot hardness testing, this is done at ambient temperature for the same reason above.

Thanks for confirming my thoughts on this topic. This forum is great!

I think you mean PQR...not WPQ.
