ASTM A 262 "Practice F" on Incoloy 825 for IGC test.
(OP)
In one of the specification I have found that client has asked for Inter Granuler Corrosion test as per ASTM A 262 Practice F for Incoloy 825 cladded pipe. But test conducted by the manufacture resulted in corrosion rate more than required minimum as per the specification. But now the manufacture has suggested that ASTM A 262 Practice F is not applicable. They suggested ASTM A 262 Practice B for the same. Now can any body aprise me whether the manufacturer is correct in their suggestion.

Actually G28 might be a better standard. I'll look up those tests.

On page 59, they provide Acceptance Tests and Criteria for corrosion-resistant alloys. For Incoloy 825, the applicable test is ASTM A 262 Practice C.
