TESTS

         * electrolitic currents
The   JB  is  made  by  two  slightly  different  Titanium alloys: BT-23 for the hemispheres and Ti 6 Al 4 grade 5 for the spacer.  Possible galvanic currents between   the two   alloys  can be   created   in the   sea environment: this test
describes the result obtained in the lab.

          * corrosion
A small sample of Titanium grade 5 was merged in sea water for a period of two months: this test compare the material before and after immersion

           *heat dissipation
The JB   houses  the main  26 KVoltAmpere transformer and some active components which produce ~ 1 KWatt of power.  The test performed in our laboratory measures the temperature inside the JB in different conditions and determines the configuration where the heat dissipation is optimised.
