Purpose of Tests
- • The effectiveness of protective covers, cases, and seals in preventing the penetration of water into the material.
- • The capability of the materiel to satisfy its performance requirements during and after exposure to water.
- • Any physical deterioration of the materiel caused by the rain.
- • The effectiveness of any water removal system.
- • The effectiveness of protection offered to a packaged materiel.
Industry Applications
Three Procedures
- Procedure I - Rain and Blowing Rain. is applicable for materiel which will be deployed out doors and which will be unprotected from rain or blowing rain.
- Procedure II - Water tightness. Consider Procedure II when large (shelter-size) materiel is to be tested and a blowing-rain facility is not available or practical.
- Procedure III - Drip. is appropriate when materiel is normally protected from rain but may be exposed to falling water from condensation or leakage from upper surfaces.
