[MW:634] Etch structure acceptance in IGC test per ASTM A262

ASTM A 262 Practice E does not specify anything about the acceptance of Interdendritic ditch structure (refer Table 5)

 

Where as in others (like in practice C it is specified in non acceptance category)

 

When a report specifies for weld IGC as Interdendritic ditch structure, is it acceptable?
