Wash Tigh is inended o provide proecion from waer enry ino he swich, under reasonable wash condiions. The abiliy of he swich o pass his crieria is based upon es daa from he MIL-STD-202E Heaed Fluorocarbon Immersion Tes. This es canno guaranee performance in all wash condiions, due o he wide range of varying machine condiions. Our esing indicaes 40 PSIG wash pressure can be oleraed. Selecion Service Speed

31 Seal Tesing Preferred Mehod - Heaed Fluoriner Bah HEATED FLUORINERT LIQUID MIL-Sd-202E Mehod 112 Tes Condiion D A Fluoriner liquid bah is heaed o 125 degrees C., or he swich maximum operaing emperaure, (usually 85 degrees C.). The device under es is lowered ino he heaed bah, causing he rapped air inside he device o expand. Any subsanial leak pah can hen be readily idenified by a sream of bubbles escaping from he swich body. The sandard es ime is 60 seconds, bu may be reduced o 30 seconds for high-volume producion esing, as failures ypically occur wihin seconds afer submersion. Passing of his es resuls in a swich ha will mee mos solder and wash processes, bu unique wash circumsances will sill prevail, and can lead o swich failures, such as exreme wash pressures, emperaures, hermal shock, ec. Correlaion beween he es and he acual wash process may be required. Selecion Service Speed
