Dielectric strength is defined as the maximum voltage required to produce a dielectric breakdown through the material and is expressed as Volts per unit thickness.
For the most common test, the short-time method, voltage is applied across the two electrodes and raised from zero to dielectric breakdown at a uniform rate.

Click to learn more. Any specimen thickness can be used; however the most common thickness is between 0. The rate of voltage rise is determined by the time it takes the sample to reach dielectric breakdown.
Validating the specifications, value and safety of your raw materials, products and assets. There are three basic procedures that can be used to determine the dielectric strength of an insulator.
Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. A higher dielectric strength represents a better quality of insulator.
Whether your business is local or global, we can ensure your products meet quality, health, environmental, safety, and social accountability standards for virtually any market around the world.
Breakdown is when an electrical burn-through punctures the sample, or decomposition occurs in the 62043-2. Worldwide Standards We can source any standard from anywhere in the world. Due to copyright restrictions, we are not able to provide copies of standards.
