I need your help.

Plate Material : 1) SA 516 Gr 70 (Normalized)
Thickness : a) 19 mm and b) 12.5 mm

Is impact testing is require for 1a and 1b.

Your help will be appreciated.

If you look at UCS 66 the 19mm would require impact testing. The 19mm is good to -42F and the 12.5mm is good to -55F

If you do not want to inpact test you could apply the rules of UCS 68 (c) and UCS 66 (c). Hope this helps

Here's a pretty good article to help out people who are not too familiar with the rules...
