What exactly is UL94? The UL94 common is a commonly acknowledged exam system utilized to find out the flammability of plastic resources Utilized in electrical units and parts.
Glow wire flammability examination is usually to simulate Should the overheated metallic of electrotechnical products will lead to ignition and have the potential of fire risk or not.
This glow wire take a look at equipment is accessible in different specialized requirements. This glow wire take a look at equipment is out there in different designs and specifications to meet the wants of the appliance.
Glow Wire Examination Apparatus is accustomed to check In the event the analyzed item provides a hazard of fire by overheating metallic elements
d) The tip of the glow-wire is introduced little by little into contact with the specimen for 30s±1s. An approximate level of tactic and withdrawal will be 10mm/s to 25mm/s. Nonetheless, the speed of technique shall be decreased to zero upon contact to advoid forces of impression exceeding 1.
The examination benefits can be considered favourable if no ignition takes place or if ignition happens and the flame or glow of your test sample extinguishes within just thirty seconds soon after elimination from the glow wire along with the tissue paper underneath the take a look at sample is not ignited.
These equipments are manufactured using high quality Uncooked resources and with the latest methodology in order to sync with the Global specifications. Our tests devices is highly acclaimed by our
The GWFI is really Glow Wire tester a take a look at with the ignition temperature. Should the flame of your sample is extinguished within thirty seconds once the elimination from the glow wire, the sample just isn't ignited through the packaging paper under the sample, and also the sample will not ignite, then this temperature can document as a go.
a) Mount or clamp the specimen While using the flat test surface area vertical plus the tip in the glow-wire centered to the specimen area.
C. Push the "Heating" button to regulate The present adjustment knob. According to the necessities with the sample, alter the suitable latest price, although Glow Wire tester the temperature is required to meet the exam requirements of the required temperature.
A scale offers simple reading of any flame heights which will come about. The sample carriage might be set previous to the check to limit the glow wire penetration to the optimum of 7mm.
