The sample passes if there isn't a flame or if any flame extinguishes inside 30 seconds after the glow-wire’s removing, offered which the tissue paper would not ignite. Certain requirements may perhaps range depending upon the applicable specification.
Exactly what is UL94? The UL94 typical is often a broadly acknowledged exam system utilised to ascertain the flammability of plastic products used in electrical products and elements.
If the test is performed on the finished part, It's not necessarily only the fabric itself that's analyzed. The design and any steel inserts will likely affect the outcome.
A loop of resistance wire is electrically heated to your specified temperature and also the specimen currently being analyzed is introduced into connection with this heated wire with an outlined horizontal loading. Observations and measurements are made To judge the hearth hazard introduced from the specimen throughout exposure to elevated temperatures.
Timing Unit: the timing device will count for the time of application of the glow wire, the time of ignition, enough time of extinguishment
Despite the fact that a person sample suffices, more samples are proposed just in case more screening is necessary. Selected requirements might mandate extra samples.
The take a look at benefits might be viewed as good if no ignition occurs or if ignition happens and also the flame or glow on the check sample extinguishes within 30 seconds just after removal in the glow wire and the tissue paper under the exam sample just isn't ignited.
The glow wire temperature must be set up Glow Wire tester 1st. Heating the glow wire to get to the necessary temperature.
Our manufacturing device is equipped with most up-to-date technological know-how and easy general performance device that are effective at handling bulk of specifications created by our useful customers all through the earth. We emphasize on the standard, which is clear from the primary face with our well-skilled associates.
four, Geared up with mesh transfer sample fixture to aid the clamping of special-formed and small test objects.
Throughout this examination, the duration and height of the flame and also the formation of droplets on the tissue paper are carefully documented. Send us your ask for for even more data.
The exam shall be completed inside 30 min once the pre therapy under the standard testing natural environment.
If an item employs unqualified combustible components while in the generation system, there would be a significant hearth threat of those elements due to varied causes in the event the Glow Wire tester gadget is jogging.
The ignition resource is imitated by an electrically Glow Wire tester heated wire loop against which the sample is pressed with a relentless drive. A miniature jacket thermocouple serves as being a sensor to the loop temperature.
