[MW:5838] Acceptance criteria for Porosity??

Dear all,

For Porosity, I let to know, Acceptance criteria is Appendix 4 ASME 8
div 1,
In that, 4.2 - b, c, d, f, & h. & Table 4-1 is there,
They are given as b) relevant indications
c) Maximum size for rounded indications
f) Charts.
and Table 4-1.

This is confusing, What we have to refer for a porosity in 6 inch weld
film

and in table 4-1, they given as Maximum Size of Acceptable rounded
indications & Maximum size of Non relevant Indications. What they are
said in the table.

Pl clear about that....

and for example weld thick is 12mm, wat's the accepatance limits.?
