A Comparison of the New and Old Standards for the Glow Wire Apparatus

Issuing time:2023-02-06 10:38Author:Pego ElectronicsSource:Pego Electronics

The IEC60695-2-10 standard is a common test method for testing the flame retardant performance of materials used in electrical products. During use, the product may reach excessive temperatures due to overload, short circuit, electrical contact or other fault conditions that can cause a fire hazard. The glow wire test is to simulate the overloaded resistance heat source to apply thermal stress to the sample in a short time, and to evaluate the fire risk of the sample through observation and measurement. The glow wire test is suitable for resarching, production and quality inspection departments of electrical and electronic products, such as lighting equipment, low-voltage electrical appliances and household appliances, machine tool appliances, motors, electric tools, electronic instruments, electrical instruments, information technology equipment, electrical equipment and their components, and also applicable to insulating materials, engineering plastics or other solid combustible materials industry.


There is difference on glow-wire apparatus in version 2013 and version 2000 of standard IEC60695-2-10, the details as below:

Item

IEC60695-2-10:2000

IEC60695-2-10:2013

Glow-wire

Nickel/Chromium (80Ni/20Cr)

Nickel/Chromium (>77%Ni/19~21%Cr)

Diamater of glow-wire

4.00mm±0.04mm

(3.96mm~4.04mm)

4.00mm±0.07mm

(3.93mm~4.07mm)

Applied force

1.0N±0.2N

0.95N±0.10N

Diameter of the thermocouple

0.5mm (priority) or 1.0mm

1.0mm

Calibrated temperature

960℃±15℃

960℃±10℃

Draught-free environment

NONE

Space in which the results of experiments are not significantly affected by the local air speed. For small-scale fire tests, the maximum air speed is 0.1m/s or 0.2m/s


The purpose of the revision of the IEC 60695-2-10 standard is to reduce the influence factors of the test environment and equipment on the test results. The change in the diameter of the thermocouple greatly reduces the damage rate of the glow wire. The glow wire tester (models GW-1 and GW-1H) produced by PEGO can completely meet the requirements of the latest standard.
