Flammability Testing Equipment IEC 60112 Tracking Index Touch-Screen Operation
Standard:
IEC60112-2009 Method for the determination of the proof and the comparative tracking indices of solid insulating materials.
Application:
It is used for determination of the relative resistance to tracking performance that solid electrical insulating material under the action of an electric field, when the surface exposed to water containing impurities. Flammability Testing Equipment
The test apparatus and test procedure consist of:
1. Two electrodes of platinum with a minimum purity of 99 %.
2. Test circuit with a substantially sinusoidal voltage, variable between 100 V and 600 V at a frequency of 48 Hz to 62 Hz.
3. Test solution A and solution B.
4. Dropping device. Drops of the test solution shall fall on to the specimen surface at intervals of 30 s ± 5 s. The drops shall fall more or less centrally between the electrodes from a height of 35 mm ± 5 mm. Flammability Testing Equipment
