Corrosion testing is an essential tool in the development of corrosion protection strategies. Its
prominence cannot be overlooked in this world of limited resources. Accelerated tests including the alternate
immersion test and the simple immersion test, were performed according to ISO 11130 and ASTM G31 to study the
corrosion behaviour of mild steel. A time correlation has been established between these tests and the corrosion
categories of ISO 9223 to get an idea about the testing period for a particular amount of expected corrosion loss in a
specific atmosphere. They were also compared with atmospheric exposures at a marine site in Mauritius. Test
specimens were visually inspected to understand the corrosion behaviour in these accelerated tests. The study
concluded that a concentration other than 3.5% NaCl should be envisaged for the alternate immersion test to at least
follow a trend similar to that of atmospheric corrosion.
