Hello ,
 
Please guide about the definition of the Casting quality level .
Where I can find about the quality of casting as 1, 2 or 3.
 
Also I am not able to understand the Acceptance level ( or class ) specified in ASME 31.3 Table 302.3.3 D.
 
Where can I find this casting level defined ?
 
kind regards
Rahul Pisat
