ASTM D3638-92 Electrical Flammability Low Voltage Tracking Testing Equipment
Description:
ASTM D3638-92 low voltage tracking tester simulates wet/moisture condition, test tracking index(CTI) and anti tracking index(PTI). It is used for electrical electronic products, solid insulating materials of household electrical appliance and other products.
Test method:
On the surface of solid insulate material, at the ruled 2mmx5mm platinum electrode, exert a certain voltage and set 30s time, drip the ruled drop volume(0.1%NH 4CL) at 35 mm height, then evaluate solid insulation material surface under combined electric field and medium pollution tolerance ability, determine its tracking index(CTI) and anti tracking index(PTI).
