Dip-Track Test

A new tracking test has been designed which substantially eliminates the faults of the standardized tracking tests. It has been used successfully over the past three years in the evaluation of the tracking resistance of cable insulations. Utilizing a liquid contaminant of ammonium chloride, tracking resistance measurements can be molded panels or on cable sections in a very short time with excellent reproducibility. A correlation of the results obtained using the Dip-Track Test and the Inclined Plane Test is shown. A test method for the evaluation of tracking resistance with the Dip-Track Test equipment is presented. Also, a description of the equipment with schematic electrical and mechanical drawings is given.
