Hot wire testing equipment is mainly used to evaluate the quality, performance, and safety of heating elements. Common equipment includes hot wire testers and X-ray non-destructive testing equipment. Here is a detailed introduction to these two devices:

1. Hot wire tester

The hot wire tester is a device used to evaluate the combustion performance of materials and is widely used in the electrical and electronic industries. Its main characteristics and working principle are as follows:

Working principle: Heat the material to the set temperature (usually 200 ℃~1250 ℃) through an electric heating wire, and then contact the heating wire with the test sample to simulate the combustion performance of the material under overheating or short circuit conditions.

Composition: The equipment includes a heating system, temperature control system, sample clamping device, and safety protection system.

Application areas: Mainly used to evaluate the flammability and self extinguishing performance of materials such as plastics, insulation materials, and electronic component casings.

Advantages: Compliant with international standards (such as IEC 60695-2-10), easy to operate, high repeatability and reliability of test results.
