Product Description:-

IEC60695 Glow Wire Test Machine

1. Application

 

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

 

This testing machine is used to evaluate the ignition risk of thermal stress caused by a heat source such as a burning element or overload resistance in a short time. Applicable to electrical and electronic equipment and its components, but also for solid electrical insulation materials or other solid combustible materials

 

2. Reference Standard

 

GB/T5169.10, IEC60695, UL746A

 

3. Test Principle

 

Heating wire test using flameless ignition source (Heating wire is a standard resistance wire ring) It uses electric heating to a specified temperature, and then under test conditions, makes the heating wire touch the tested sample.

(1) Chamber capacity: 0.5 m3, width * depth * height: 950 * 600 * 900 (mm)

(2)Outline size: 1200 (L) x 600 (W) x 1080 (H) mm

(3)Hotwire: made of nickel/chromium with a diameter of 4mm.

(4) Thermocouple: 0.5 mm diameter armored filament thermocouple, which can withstand high temperatures of 1050℃.

(5) Heating current: when the temperature is 960℃, the current is between 120 ~ 150 A.

(6) The force applied to the test is 0.8 ~ 1.2 N, and the penetration depth is at least 7 mm.

(7) Timer: ignition duration (Ti) and flame extinction time (Te).

(8) Outer box material: stainless steel

Frequently Asked Questions:-

What is Glow Wire Test Machine?

It is a simulation UL746A and other standards that use non-flame test item of IEC 60695-2-10, ignition source program. The specified of the heating wire (Φ4 mm resistance heating material (Ni80/Cr20) and shape alloys to the test temperature glow wire test apparatus rule the with a large current.
