220V 50Hz Flammability Testing Apparatus Glow Wire Tester For Comprehensive Fire Hazard Evaluation


Products Introduction


A glow wire test apparatus based on PLC control and touch screen operation. The equipment complies with relevant international standards and can be used for flammability testing of electrical and electronic products, household appliances and other materials.This device is manufactured according to the standard of IEC60695-2-10, IEC60695-2-13. It also conforms to the standard requirement of UL746A. 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.


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.

Preparation Before Test


Install the specimen so that the tip of the glow wire points to the center of the specimen.

Place the specified layers below the specimen.

Press the [Forward] button, and immediately press the [Stop] button when the specimen contacts the glow wire.

Adjust the position of the automatic timing: slowly adjust the proximity switch to move it to the fixture, when the proximity switch indicator light is on, lock the screw at this position where the specimen just touches the tip of the glow wire, and the timing starts automatically.

Press the [Reset] button to move the fixture away from the glow wire.

Press the [Forward] button to ensure that the fixture stops automatically and the timing starts when the sample touches the glow wire.

Press [Reset] to move the fixture backward.


Precautions


Prevent electric shock, scalding, burning or fire accidents.

Prevent inhalation of toxic gases or smoke.

Prevent damage to human health caused by toxic residues.

Have over-temperature and low-temperature protection functions, and the heating will stop automatically when the heating time exceeds 5 minutes.

Turn off the fan during the test and turn it on after the test is completed.

Summary

The PLC-controlled glow wire flammability testing equipment with touch screen operation complies with IEC60695 standards. It's designed for testing various products' flammability by simulating thermal stress.With technical parameters like 220V/50Hz working voltage and specific glow wire details, it offers accurate and convenient testing. Test preparation involves specimen installation and button operations. Precautions include accident prevention and proper fan use. Overall, it meets scientific research and safety requirements in the field of flammability testing.
