minimum impact values for steel at 46 centigrade ASME Impact Test Requirement - inspection-for-industry

For this example our minimum permissible temperature would be -36-30=-66 degree F, and your MDMT is -45 degree F, so you are exempted from impact testing. Now the worst case in the above, assume you need to have -70 degree F for your MDMT; you can see with this new condition you cannot be exempted even by UCS-68(c) and you have to carry out impact testing.
