This may be one of the properties of polymers and plastics that have the largest number of tests methods for evaluation. No different in this regard is the ASTM D3638 test method for comparative tracking index. Our company is involved in manufacturing Comparative Tracking Index Tester which is used to determine the comparative tracking index of solid insulating materials as per IEC 60112 2003-01. This tester works in a very precise manner and determines the resistance to tracking in insulating parts supporting live parts used for electrical Idea in BriefImproving the Comparative Tracking Index allows smaller packages to achieve high working voltages.The maximum working voltage of an isolated system depends on a number of parameters according to IEC 60950. These include creepage distance, pollution degree, and material group. Pollution degree, a measure of the surface contamination, is Comparative Tracking Index [CTI]. In printed circuit board fabrication, CTI is a measure of the ability of the laminate surface to withstand tracking [carbonneous tracks on the surface, under wet contaminated conditions] across two electrodes placed on the surface, when an electrolyte is dropped between them. comparative tracking indices of solid insulating materials on pieces taken from parts of equipment and on plaques of material using alternating voltages. The standard provides for the determination of erosion when required. NOTE 1 The proof tracking index is used as an acceptance criterion as well as a means for the quality control of CTI / tracking IEC 60112 This method is used to assess the relative resistance of insulating materials to tracking.
Comparative tracking index (CTI) is used to assess the relative resistance of insulating materials to tracking. The CTI expressed as that voltage which causes This method is used to assess the relative resistance of insulating materials to tracking. CTI/tracking. Test specimen, ≥50 mm x ≥50 mm x ≥2,5 mm. Test
The ability of a material to withstand tracking is quantified by a comparative tracking index (CTI). IEC 60664-1 classifies materials into four material groups CTI (V) : Comparative Tracking Index. ε (F/m):, Permittivity. DB (kV):, Dielectric Breakdown. TST: Thermal Stress Test. IPC-4101: material category

D5288-14 Standard Test Method for Determining Tracking Index of Electrical Insulating Materials Using Various Electrode Materials (Excluding Platinum) tracking resistance~ copper electrodes~ comparative tracking index~ aqueous contaminants~ ~ The Comparative Tracking Index (CTI) is used to measure the electrical breakdown (tracking) properties of an insulating material.Tracking is an electrical breakdown on the surface of an insulating material wherein an initial exposure to heat chars the material, and the char is more conductive than the original insulator, producing more current flow, more heat, and eventually complete failure.
