INTRODUCTION: In cyclic corrosion testing@ test specimens are exposed to at least two different types of environmental conditions and cycled from one environment to the other. International paint film damage prior to testing@ such as scribing or exposure to gravelometer@ is usually an essential part of the test procedure. The Cyclic tests make use of many types of environments@ such as ASTM B-117 salt spray@ immersion in a 5% salt solution@ or an exposure to dry and/or cold conditions. A humid environment or water immersion of the test specimens is included in most test. In other cases@ a thin layer of clay is applied to the specimen surfaces. ASTM D2933-74 is an example of a cyclic test. This test consists of only two types ofenvironments: A. ASTM B-117 salt spray and B. ASTM D-2247 Humidity
