IEC60695-2-10 Flammability Testing Equipment With Ni77/Cr20 Glowing Filament
Introduction: Flammability Testing Equipment
The Glow-wire ignition Temperature(GWIT)is to be assigned as the temperature which is 25°C (45°F) higher than that temperature of the tip of the glow-wire which does not cause ignition during three consecutive tests.
Either during normal operation , under unusual conditions , or as a result of malfunctions , some components of an electrical apparatus , such as wires or other conductors may become abnormally hot.
When these overheated parts are in intimate contact with the insulating matmay occur . This test is intended to determine the relative ignitability of insulating materials under these conditions. Flammability Testing Equipment
Standard:IEC60695-2-10, IEC60695-2-13 and UL746A.
Application:This device simulates the thermal stress test of glowing component or heat source like overload resistance or ignition source which is caused in a short time. It is suitable for electric and electronic products, household appliances and other material to do fire hazard testing. It is also used in the No flame ignition source fire test to test initiation temperature and flammability index of related glowing filament.
Test sample:Electrical equipment and its components and parts, solid electrical insulating materials and other solid combustible materials. Flammability Testing Equipment
Feature: This equipment adopts a new design concept, while in the realization of accurate positioning, but also to achieve the rapid adjustment after replacing the sample, truly meet the requirement of easy and convenient operation; The control system adopts PLC and touch screen control, each parameter can reflect the real situation of the relevant parameters more timely and accurately, and the operation is intuitive and convenient, so as to meet the needs of scientific research Flammability Testing Equipment
