If materials with incorrect heat treatment enter service, they are liable to crack or fail by intergranular corrosion (IGC) much more rapidly than properly treated materials ASTM A767 is a screening test to help find batches that are incorrectly processed. Non-destructive tests are conducted on a full length of a hose or hose assembly and are for the purpose of eliminating hose with defects which cannot be seen by visual examination or in order to determine certain characteristics of the hose while it is under internal pressure.

Astm D 3951 PdfThe first and fastest step is the ASTM A767 Practice A, a rapid (same-day) screening method in Oxalic acid to determine the susceptibility to intergranular corrosion.
Intergranular corrosion shows up as the dark black lines around the grain boundaries. Classification of the structure after A767 Practice A analysis will determine if the material is acceptable or if additional testing is required.
