Glow wire tester

F242 Glow-wire tester simulates thermal stress from heat sources to test circuit component flammability, widely used in electronics, appliances, etc. It predicts circuit safety, controls production, and verifies performance. The test applies short-term heat to samples, assessing fire risk by observing light-off states. It measures ignition hazards of materials by burning them at specified temps and pressures.

Application

It is used in the evaluation of flammability tests and light-off temperature tests for electrical equipment and its components and accessories, as well as solid electrical insulating materials or other solid flammable materials.

It is used for the test of ignition hazard of electronic and electrical products, the evaluation of hot burning performance and the test of high temperature resistance.

It is used to determine the light-off property, light-off temperature, flammability and flammability index of solid insulating materials and other solid combustible materials.

It is used to test flame retardant properties for the insulated enclosure of household appliances, switch panels, printed circuit boards,and insulating materials.

It is applicable to the performance verification of new products, quality control of the production department, and the of material properties for the third-party testing organization, the product performance verification laboratory, and the quality and technical supervisiondepartment, etc.

Sample rack dis-assembly type design

The sample holder of the test device can be removed for loading and cleaning,and it use physical pressure, which has precise pressure,convenient operation and high efficiency.

Parameters

Test Procedures

The operating procedure for the hot-wire test apparatus includes the following steps:

Checking the instrument: Turn on the power switch and check if the instrument is functioning properly.

Setting the temperature: Adjust the temperature to the required test temperature and wait until the temperature display shows the desired temperature.

Starting the test: Press the start button to begin the test.

Observing the test sample: Observe the residue dropped from the test sample during combustion.  Press the stop button immediately when the sample stops burning.

Recording the results: Record the flame height during combustion. At the end of the test, press the exhaust button to remove the smoke.

Cleaning the equipment: Turn off the power switch, remove the test sample, record the test results, clean the dirt inside the chamber, close the exhaust vent, and turn off the main power switch.

These steps ensure the accuracy and safety of the hot-wire test apparatus. Operators should receive regular training to ensure the reliability and comparability of the test results.
