A large voltage difference gradually creates a conductive leakage path across the surface of the material by forming a carbonized track. Testing method is specified in IEC standard 60112 and ASTM D3638. To measure the tracking, 50 drops of 0.1% ammonium chloride solution are dropped on the material, and the voltage measured for a 3 mm thickness is considered representative of the ma… WebJan 1, 2024 · ASTM D3638-93 (1998) May 1998 Standard Test Method for Comparative Tracking Index of Electrical Insulating Materials Historical Version Browse related products from ASTM International ASTM International > By Sections and Volumes > Section 10 - Electrical Insulation and Electronics > Volume 10.02 - Electrical Insulation (II): D 2518 - …
