Re: Re: [MW:29282] REQUALIFICATION OF PQR

Qw-401.3

When a procedure has been previously qualified to
satisfy all requirements other than notch toughness, it is
then necessary only to prepare an additional test coupon
using the same procedure with the same essential variables,
but additionally with all of the required supplementary
essential variables, with the coupon long enough to
provide the necessary notch‐toughness specimens.

Dear Mr.

Thank you so much.

Based on this paragraph, impact test is enough.

Regards.

Dear All.

If a supplementary essential variable changed such as group no., now the new PQR just need to be impact tested or other mechanical tests also needed to repeat?

Regards.
