IEC 60695-2-20 Hot Wire Ignition Tester

The RSY-LT Hot Wire Ignition Tester is a precision testing apparatus engineered to evaluate the ignition characteristics of solid insulating and combustible materials in accordance with IEC 60695-2-20. This instrument simulates ignition risks from overheated electrical heating elements, such as resistance wires or motor windings. Through precise control of hot wire temperature, pressure application duration, and contact force, it determines the material’s hot wire ignition temperature (HWIT) and hot wire flammability index (HWFI), providing essential data for material selection, product safety engineering, and regulatory compliance certification.

The RSY-LT Hot Wire Ignition Tester features an integrated structural design, incorporating a hot wire heating control system, specimen clamping mechanism, and combustion monitoring module. This configuration enables automated test process control, minimizing operator-induced errors and ensuring measurement accuracy and repeatability. It is extensively utilized in electrical and electronic manufacturing, appliance production, renewable energy sectors, and insulating materials industries. The apparatus is suitable for testing hot wire ignition performance of various solid combustible materials including polymers, elastomers, and composite materials. It meets rigorous testing requirements for research institutions and accredited third-party testing laboratories.
