Could you clarify what is the application code? Section I, section VIII-1?

Subject: [MW:4661] ER70S-3 for low temperature application
Hi members,
Please provide a suggestion for the following query.
I have qualified a PQR for GTAW+SMAW with ER70S-3 & E7018-1. The PQR is impact tested at - 46 deg C at root(GTAW) and filling (SMAW) and passed (Min. 50J energy obtained).
As per ASME Sec.II part C, E7018-1 will support up to - 46 Deg C, but ER70S-3 will support up to - 20 Deg.C only.
Since I have proven the toughness through PQR, can I use this PQR for job with impact test requirement of - 46 Deg C, even ER70S-3 does not support for this temperature as per Sec.IIC?.
Thanks & Regards
Muhammed Ibrahim PK
