Complied Standards & Clauses

IEC60695-2-20 “Fire hazard testing - Part 2: Glowing/Hot wire based test methods - Section 20: Hot-wire coil ignitability test on materials”

Equipment Overview

Application: Suitable for fire hazard tests on solid electrical insulating materias of information technology equipment, low-voltage switchgear and control equipment parts, etc., simulate the thermal stress caused by hot components or overload resistance or ignition sources in a short time.

Test Principle: Adopts the electric heating wire of specific size (ф0.5mm length 250mm) and specific material (Ni80/Cr20). After the specified heating power (0.26W/mm) and the specified time (8s～12s) are pre-annealed, according to a certain winding tension (5.4N) and a certain winding distance (6 or 6.35mm), wind 5 full turns on the sample, test the sample with electric heating wire under the specified heating power (0.26W/mm) for 120s, and evaluate its fire hazard based on whether the sample is ignited or ignition time

Structure: Chamber structure, with fume hood.
