IEC60695-2-10 Glow / Hot Wire Flammability Testing Equipment for GWIT and GWFI Testing
1. Introduction of Glow Wire Flammability Testing Machine
Glow wire flammability testing equipment is an electrical safety test designed to evaluate the flame resistant properties of plastic materials used in electrical devices. The purpose of glow wire flammability testing equipment is to protect against the risk of fire from overheated or electrically energised parts which may cause the plastic material to ignite. This may occur in normal use, under reasonable abnormal use, malfunction or failure of the product. The glow wire simulates an over-heated part which then comes into contact with plastic materials
The glow wire flammability testing equipment is designed according to IEC60695-2-10, UL746 and GB/T5169.10. The specific material and sharp heating wire is heated to specific temperature (550 ℃~960 ℃) for 1 min by max current, then vertical burns the EUT with certain pressure (0.95N) for 30s, then check if the test specimen and bedding material are burning, and count the burning time to judge the dangerousness of the specimen. Generally it is applied to test flammability, GWIT and GWFI of lighting lamps, electronic products and household appliances The equipment is applicable to flame resistance test of all levels of QC departments and corresponding enterprises.

3. FAQ of Glow Wire Flammability Testing Machine
1). What are GWIT and GWFI?
Answer: GWFI——glow-wire flammability index. Within 30 seconds after removing the glow wire, if the flame of the test sample is extinguished, the packaged crepe paper under the sample does not ignite, and the sample does not ignite, then the temperature can be recorded as acceptable. If the above conditions are not met, you will need to select a lower temperature for testing. The maximum temperature that can be achieved by three consecutive experiments plus 25k is the glow wire light-off temperature.
GWFI——glow-wire ignition temperature, GWIT is the lowest temperature at which the material will ignite and the burning time exceeds 5 s when the heating element is in contact with the sample.
2). What is the warranty period of the glow wire flammability
testing machine?
Answer: the equipment warranty is 12 months upon you receipt of the
equipment
3). Can you provide third-lab calibration certificate of the glow
wire flammability testing machine?
Answer: Yes, the equipment can send to the third-labs authorized by
ISO17025 and get the calibration certificate, but the buyer should
undertake the charges.
4). Does the glow wire flammability testing machine have English operation interface?
Answer: of course, yes, the operation interface has English instruction.
5). Your power plug can not be used in our country, can you change
it for us?
Answer: yes, we will change the power plug to fit your demands,
please subbmit this issue when you make order.
6). Do you have CE ceritifcate for glow-wire flammability testing machine?
Answer: Yes, this equipment has CE certificate
