Intergranular corrosion chloride solution ASTM

ASTM Standard G 110, Standard Practice for Evaluating Intergranular Corrosion Resistance of Heat Treatable Aluminum Alloys by Immersion in Sodium Chloride + H2O2 Solutions, Annual Book of ASTM, 1999, 03.02. 

GllO-92, Standard practice for evaluating intergranular corrosion resistance of heat treatable aluminum alloys by immersion in sodium chloride + hydrogen peroxide solution. Annual Book of ASTM Standards, ASTM International, Philadelphia, Pa., 2000, p. 481, Vol. 3.02. 

Susceptibility to intergranular corrosion dep>ends primarily on the typ>e of alloy and fabrication process and can occur in most environments. The six-hour ASTM G 110 test (Practice for Evaluating Intergranular Corrosion Resistance of Heat Treatable Aluminum Alloys by Immersion in Sodium Chloride + Hydrogen Peroxide Solution) is most often used to determine inherent susceptibility to this form of corrosion. However, users are cautioned that the degree of susceptibility in this accelerated test may not be representative of p>erformance in outdoor atmospheres [22].
