EUROLAB, with its state-of-the-art accredited laboratories and expert team, offers precise and rapid testing services within the scope of DIN 53480 testing. Specification for electrical testing of insulating materials focusing on insulation resistance typically relates to the ability of the material to withstand the formation of conductive paths on its surface under certain conditions.
The tracking index determined by the test method presented is an important tool for quality control of materials and fabricated parts. It is also used as an acceptance criterion. The comparative tracking index is mainly used for the basic characterization of materials and comparison of their properties.
This test method evaluates both the surface properties of the material under consideration and the composition of the material. Both composition and surface condition directly affect the results of the assessment and are taken into account when using the results in the material selection process.
Meanwhile, there are longer-term and more rigorous test methods for evaluating the performance of materials for outdoor use using higher voltages and larger test samples. For example, the IEC 60587 standard provides test methods for monitoring and evaluating resistance to erosion for electrical insulating materials used in severe ambient conditions.
Briefly, this standard is used to evaluate the relative resistance of insulating materials to monitoring. The comparative tracking index is used to measure the electrical breakdown (tracking) properties of an insulating material. Trace is an electrical disturbance that occurs on the surface of an insulating material. During initial exposure to electric arc heat, the material becomes carbonized. Carbonized areas are more conductive than pure insulator and increase current flow. This causes increased heat production and eventually the insulation becomes completely conductive.
