20、rospace series - Cables, electrical, aircraft use - Test methods, Pari 302 - Voltage proof test 3. PREPARATION OF A SPECIMEN The preparation of a specimen shall consist in winding a sufficient length 01 completed cable around itself at least 1 O times, so that the cable itself acts as a mandrel. 4.
21、APPARATUS An air circulating oven shall be required for this test. 5. METHOD 5.1 . Procedure The prepared specimen shall be placed in the oven at a temperature of (31 O +5)“C for 2 h. After the 3 h, the specimen shall be removed from the oven and cooled for at least 1 h at ambient temperature. 5.2 .
22、 Requirements After being returned to ambient temperature the PTFE cable insulation shall show no cracking or debonding of layers along the insulation. The specimen shall pass the voltage proof test requirements specified in EN 3475-302 : - after being wound before aging, - after aging ,still wound,
23、 - after being unwound and straightened.
