Insulation Resistance:...............DC 500V 100M Ohms Min. between Primary
                                         winding and Secondary windings and
                                                  between windings and core
Heat Test:...............Transformer must be conditioned for 7 hours in 40C
                         ambient temperature.  After this test, transformer
                                must be able to withstand high pot test and
                        insulation resistance must be larger than 10M ohms.

Lead (Pin, tensile test):....................Leads (Pins( must be withstand
                                              a pull of 2Kg for 10 seconds.
Humidity Test:..................Transformer must be conditioned for 6 hours
                                in 40C ambient temperature at 90 to 95% RH.
                             After this test, transformer must be withstand
                                    pot test and insulation resistance must
                                                     be larger than 5M ohms
Inpregnation:.......................................................Varnish
