Re: [MW:35197] Clarification on Subsize Impact Specimens for PQR According to API 650

Any one can help to give more details about how to calcul the heat put for 347. During welding

 Dear Experts?

We obtained a value of 26J(avg) for P1 G2 material during procedure qualification with impact requirements, whereas the acceptance criteria according to API 9.2.2.5 is 27J(Avg). We used a subsize specimen of 7.5 x 10 mm. Is there any relaxation or allowance for subsize specimens in this context? If so, where can I find this information?  

Regards,

Binto George
