IEC 60112 Test Standard Explained

Comparative Tracking Index (CTI) - IEC 60112

The voltage which causes tracking after 50 drops of ammonium chloride solution have fallen on the material.

Tracking is an electrical breakdown on the surface of an insulating material. A large voltage difference gradually creates a conductive leakage path across the surface of the material by forming a carbonized track.
