Annex A (informative) - Relationship between amount of
                        acidic stock solution added to
                        mixed salt solution and pH of
                        the resulting acidified-salt
                        solution
Annex B (informative) - Typical apparatus for accelerated
                        cyclic tests with exposure to acidified

Bibliography

ISO 16151:2005 specifies two accelerated corrosion-test procedures, Methods A and B, for the comparative evaluation of metallic materials with or without permanent corrosion protection or temporary corrosion protection in outdoor salt/acid rain environments. It also specifies the apparatus used. The two tests involve cyclic exposure of the specimens to acidified salt spray, dry and wet conditions.
