> Coming to your query, as per ASME B31.3 ASTM A 333/6 can be used below
> -45.5-deg. C (-50-deg. F as allowed by code without any special
> precautions) with following precautions:
>
> 1) Testing of Base metal at minimum design temperature (-60 deg C in your
> case.) as per B-3 of table 323.2.2 of B31.3. This is useful for the
> procurement part.
> 2) For fabrication and welding part, special precaution has to be
> specified
> for impact testing of Weld metal and HAZ. This is useful for specifying in
> the welding specification or construction specification. You will have to
> specially mention this in the p.class so that it will be highlighted to
> QA/QC or welding engineer.
>
> I hope this clarifies. Let me know if you need any further information.
