PAVE-Seal Epoxy Comparative Tracking Index

The CTI value is used for electrical safety assessment of electrical apparatus, as for instance carried out by Underwriters Laboratory. The minimum required creepage distances over an insulating material between electrically conducting parts in apparatus, especially between parts with a high voltage and parts that can be touched by human users, is dependent on the insulators CTI value. Also for internal distances in an apparatus by maintaining CTI based distances, the risk of fire is reduced. Performance Level Categories (PLC) were introduced to avoid excessive implied precision and bias. — CTI Test Results
