Property Retention After Thermal Aging

The property retention test evaluates the mechanical properties of a specimen of finished insulated wire before and after 1000 hours of thermal aging. The test methods used to evaluate the mechanical properties of the specimen after heat aging are: Dynamic Cut-Through (AS4373 Method 703) Flex Life (AS4373 Method 704) Notch Propagation (AS4373 Method 706) Read more

Forward Voltage

Forward voltage testing involves measuring the voltage drop across a diode or semiconductor junction in a cable when a forward-bias current is applied. An increase in forward voltage drop may be an indicator of an electrical component that is soon to fail. The voltage drop across the test specimen may be calculated by three methods: […] Read more
