Vinu,
ASTM 262 is the industry followed stanadrd for intergranular corrosion test. This stsndard is divdeinto 5 test categoriies:-
- Practice A- Oxalic Acid Etch Test for Classification of Etch Structures .
-
Practice B—Ferric Sulfate–Sulfuric Acid Test for Detecting Susceptibility to Intergranular Attack
- Practice C—Nitric Acid Test for Detecting Susceptibility to Intergranular Attack
-
Practice E—Copper–Copper Sulfate–Sulfuric Acid Test for Detecting Susceptibility to Intergranular Attack
-
Practice F—Copper–Copper Sulfate–50 % Sulfuric Acid Test for Detecting Susceptibility to Intergranular Attack
The best screening for sentization is possible by Practice -A test. Usually a presnce of "Ditched microsotructure" is an indication of sensitization. You may please conatct an experiences laboratory for furtherdeatils.
Thanks.
