Touch Screen Glow Wire Flammability Testing Chamber Combustion Test Equipment

Glow Wire Testing Machine/Glow Wire Flammability Testing Chamber/Combustion Test Equipment

Introduction

Glow wire tester is a simulation experiment project using non-flame ignition source in accordance to standard requirements of IEC60695-2-10,UL 746A ,GB/T5169.10,GB4706.1.It makes required material(Ni80/Cr20) and heating wire in required shape(Φ4mm-chromel-filament)heated up to test temperature( 550 ℃ ～ 960 ℃) for 1min and then broil the specimen using required pressure (0.95N) for 30s at vertical direction;to check whether the specimen and bedding material ignite and lasting ignition time to test the ignition fatalness of electrical and electronic finished devices

Test the ignition performance,ignition temperature (GWIT),solid insulating material and other solid combustible material,combustibility and flammability index(GWFI).

Application

Insulating materials or that inside the equipment a burning are prone reaches a certain temperature to flame spread other solid combustible materials element. Under certain conditions, such may be ignited by a hot wire or as the fault current overload and bad contact, some flowing through the wire, component components will and cause the nearby parts to ignite.

Product Description

IEC 60695 Glow Wire Tester Testing Equipment

Test

Left: Sample carrier small car go left

Right: Sample carrier small car go right

Exhaust: Exhausting

Light: Lighting

Heating: Adjust the current, reach to required temperature. Wait 5min to let the temperature be steady.

Start: Sample carrier automatically moves forward, timers (glow time, Ti, Te) start working, carrier returns when set glow time (30s) reached.

Glow time: 30s

Ti: The duration from the beginning of tip application up to the time at which the test specimen or the wrapping tissue placed below it ignites;

Te: The duration from the beginning of tip application up to the time when flames extinguish during or after the period of application.

Control box: When the sample start burning, press the button on control box, get ignite time Ti; when flame dies, presses the button on control box, get flame extinguish time Te.

When test finished, do not open the viewing window until exhaust for at least 2min.

Test procedure

FAQ

What is a glow wire test?

Glow wire testing used in electrical plastic materials the plastic’s ability to start or the spread of fire in devices. It assesses is performed on to if ignited. As a safety test its purpose resists ignition and to self-extinguish is to prevent the event of an electrical component becoming overheated.

What is glow wire capable of?

Glow wire compatibility is a short circuit appliance wiring failure especially mishaps caused by human mishandling, test that ensures the safety and avoids over-current, or within systems.

What is IEC 60695?

It specifies a procedure to a small-flame ignition source for comparing the relative small-scale laboratory screening burning behavior of vertically or from plastic and other non-metallic horizontally oriented specimens made materials, exposed of 50 W nominal power.
