Dielectric withstand and dielectric strength tests are used to determine the durability of insulating barrier materials in electronic devices. Our labs help evaluate insulation’s resistance to harmful voltage levels, ensuring material fitness and meeting product safety standards.
Insulation barriers protect humans from hazardous electrical currents in products and equipment. Dielectric testing is critical for ensuring peak level of voltage does not exceed the resistant properties of the barrier material, causing material damage or human injury. Our experienced experts will help identify which insulation material is best suited for your product and its intended use.
Dielectric withstand vs. dielectric strength
Dielectric tests apply a high level of alternating currents (AC) or direct currents (DC) to the insulation barrier and measure the reaction of the material. AC voltage is more commonly used in dielectric testing.
The purpose of a dielectric strength test is to reach the point of breakdown, or failure. This happens when the material experiences a sudden change in its resistance to the test voltage. The level of voltage where the barrier allows current to flow is the dielectric strength of the material.
In comparison, dielectric withstand tests are used to measure how well the insulation can hold a high voltage for a specified amount of time before the material breaks down.
