Dielectric Strength

Dielectric Strength reflects the electric strength of insulating materials at power frequencies, or the measure of dielectric breakdown resistance of a material under an applied voltage. Other said, it is the voltage per unit thickness at which a material will conduct electricity. The higher the value, the more electrically insulating a material is.

Dielectric Strength is measured in kV by mm of thickness (customary units sometimes refer to in V/mil).

Most generally used standards are ASTM D149 or IEC 60243-1.
