IEC 60068-2-52 Salt Mist Testing
IEC 60068-2-52 salt mist testing, also known as salt spray testing or salt fog testing, is intended for application to components or equipment designed to withstand a salt-laden atmosphere, depending on the chosen severity. Salt can degrade the performance of parts manufactured using metallic and/or non-metallic materials. Apart from the corrosive effects, IEC60068-2-52 testing may be used to indicate deterioration of some non-metallic materials by assimilation of salts. In the following test methods, the period of spraying with the relevant salt solution is sufficient to wet the specimen thoroughly.
The IEC 60068-2-52 test standard specifies six different severities. Severities (1) and (2) are intended to be used for testing products which are used in a marine environment, or in close proximity to the sea. Severities (3) to (6) are intended for products where, under normal use, there is a frequent change between salt-laden and dry atmosphere, e.g. automobiles and their parts. Each level of severity has a unique test requirement. For example, IEC 60068-2-52 severity one testing requires four spray periods, each of two hours, with a humidity storage period of seven days after each. Conversely, IEC-60068-2-38 severity six salt test requirements are for eight test cycles of four spray periods, each of two hours, with a humidity storage period between 20 hours and 22 hours after each. Afterwards, there is to be one storage period of three days under a standard atmosphere for testing at 23 °C ± 2 °C and 45 % to 55 % humidity.
