As already mentioned by Mr. Raghuram Bathula you have several tests
according to ASTM A262. All are related to inter-granular attack but
in different environments. Find below the solutions, test time and
acceptance criteria for your info. Be aware that for Practice B and C
the max. allowable corrosion rate should be specified by your client.
Practice B (Streicher) = 1 x 120 hours Boiling Ferric Sulfate–Sulfuric
Acid Test Solution, acceptance criteria is corrosion rate in mm/month
Practice C (Huey) = Standard 5 x 48 hours - Boiling Nitric Acid Test
Solution (sometimes also 1 x 48 hour + 1x 96 hour is used), acceptance
criteria is corrosion rate in mm / month
Practice E (Strauss) = Standard is 15 hours - Boiling Acidified Copper
Sulfate Test Solution (if required also 48 or 72 hours can be used),
acceptance criteria are cracks in the specimen after three point bend
test.

Herman Pieper
