Design codes does not specify at what point such verification is to be done. It's clients' call.
If the PMI technique is XRF, it may be performed before or after PWHT.
If the technique is OES, then many clients prefer this before PWHT, as arcing during the OES process may leave arc stains/marks . Such marks may require grinding of buffing, not usually desirable after PWHT, due to chances of human errors.
Thanks.
