Electronic Performance Testing Equipment ISO 5657 Building Materials Ignitability

Electronic ISO 5657 Building Materials Ignitability Performance 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).

Test standard:

ISO 5657 fire burning test - reaction - building products ignitability standard requirements

GB/T 14523 "building materials fire performance test method
