Etch structure acceptance in IGC test per ASTM A262
Bathula Raghuram (Mumbai - PIPING)
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?
Kannan....@linde-le.com
The practice E table 5 specifies that for all grades Ditch structure as non acceptable. step, dual, end grain I and II as acceptable structure.
This is as per A262-02a e3 edition.
With regards,
Kannan Sundaram.

Raghuram Bathula
didn't state anything about Interdendritic ditch structure
pjo...@technip.com
Practice C is applied for wrought, Cast or weld metal structure while, E is
applied for wrought or weld metal. thus, the difference remains in
acceptance criteria.
