This part of IEC 60068 provides methods of test applicable to products which, during transportation, storage or in service, may be subjected to falling drops, impacting water orimmersion. The primary purpose of water tests is to verify the ability of enclosures, coversand seals to maintain components and equipment in good working order after and, when necessary, under a standardized dropfield or immersion in water.These tests are not corrosion tests and should not be considered and used as such.The effects of a large temperature difference between the water and the specimen, such asincreased water ingress resulting from pressure changes, as well as thermal shock, are notsimulated.Established water tests in other standards are not intended to simulate natural rainfall andtheir quoted intensities are too high to be adopted for that purpose. Therefore, in addition to the high-intensity severities, Test R includes an artificial rain test based upon naturalconditions but not taking into account high wind speeds generally associated with natural rain.Guidance is given on the applicability of the tests and the severities to be selected.
