Impact Test Requirements To Austalian Standards

[Jeffro]

Hi all, can anyone help determine the Impact testing requirements for the weld procedure for the following material and conditions as there is a difference of opinion between myself and the client inspector as to what is needed.
Vessel Class: AS1210 Class 1
Material: AS1548-7-460NL40 50mm Thick
Post Weld Heat Treated at 600°C for 2 Hours
Operating Temperature: -46°C to 100°C
I believe it should be 31joules @ -40°C however the client inspector believes it is 31joules @ -50°C
thanks

without any knowledge of the impact test, if -50 deg.C is without cost implications-I suggest the inspector is closer to your optimum outcome.
