A glow wire exam is suited to fire hazard checks of electrical and electronic products and solutions, home appliances and their inner combustible components.
1. When the unit is driven on plus the Are living link elements are in lousy Get hold of, the combustible resources may possibly catch fire.
A section of the final product is subjected to a glow-wire idea at a predetermined temperature for 30 seconds. The first aim is usually to verify if this exposure ignites the sample.
Equipped with the automated Handle technique. Immediately after start off-up, the trolley loaded with specimens will instantly run on the scorching wire after which will return immediately soon after achieving the established scorching time, which makes it quick to work.
It is suggested to employ a regulated ability source, normally, the temperature will improve due to excessive voltage fluctuations.
The glow-wire check is divided into actions such as pre remedy, documentation of your exam process and perseverance of the final results, as underneath:
The sample must be mounted to some carriage on which, by the use of a tension cord, a fat which has a Glow Wire tester pressure of 1N is efficient during the way from the wire loop. Scales permit the examining from the flame peak along with the depth of penetration. Approx 200 mm below the wire loop a board of pine wood, included with a layer of tissue paper, is mounted.
The temperature controller Along with the thermocouple delivered permits precise measurement of the glow tablet temperature.
b) the flames or glowing of the specimen extinguish within just 30s right after removal in the glow-wire and there is no ignition in the wrapping tissue.
The completely computerized instrument incorporates a Manage unit circuit thoroughly shielded by fuses and also a miniature circuit breaker, as well as with a significant box on the outside for maximum operator security.
The JY Glow-Wire Tester is a totally automated instrument contained in its very own cabinet To maximise the security from the operator. The ignition supply is simulated by an electrically heated wire loop. The temperature of your loop is taken care of via a thermocouple and Glow Wire tester controller. The check specimen is then pressed versus the tip on the wire loop at a continuing 1N drive.
b) Location the reward wrapping tissue/picket board at a distance of 200mm±5mm below the spot where by the glow-wire placed on the specimen.
Perfect for companies of electrical parts and plastic materials, our custom tests tools assures substantial-high-quality thermal and flame Glow Wire tester resistance screening for reputable basic safety compliance. Created with chopping-edge technological innovation, this electrical
When the experiment is finished, eject the heating button after which you can convert The existing adjustment knob on the minimum.
