IEC 60587 Electrical Insulating Materials Resistance To Tracking And Erosion Test Machine

IEC60587 ASTMD2303 Electrical Tracking Mechanism

Technical Description:

Five groups of samples are powered on for six hours. When the sample is burned out, the equipment will give an alarm, and the results can be printed after the test.

Model: DX8427

Standard:

IEC60587-2007,   ASTMD2303.

Parameters:

Track: partially conducting path created by localized deterioration on the surface of an insulating material;

Erosion, electrical: loss of material by leakage current or electrical discharge;

Test solution used:

The mass fraction is (0.1 ± 0.002)% analytical pure NH4Cl (ammonia chloride) and (0.02 ± 0.002)% isooctylphenoxypolyethoxyethanol. The non-ionic wetting agent is matched with distilled water or deionized water.

Judgment standard of electric trace:

1. Judgment standard A:
When the current passing through the sample in the high-voltage circuit exceeds 60mA, the end point is reached. At this time, the overcurrent device cuts off the power supply and stops the test.

2. judgment standard B:
The end point is reached when the electric trace reaches the mark on the sample surface 25 mm away from the lower electrode.

The test report include:

1. model and name of tested material.
2. detailed description of sample: preparation and size, cleaning method and solvent used, sample surface (if necessary) and pretreatment, and sample thickness shall also be reported.
3. direction of the sample relative to the electrode (i.e. longitudinal, transverse, oblique, etc.).
4. voltage application method and adopted end point judgment standard.
