Feature:
The glow wire test is a method used for characterising the ignition and the flammability of polymers. A heated wire is brought into contact with the surface of the specimen at a specific temperature and for a defined time interval. During the test it is determined whether or not the material ignites within a defined period of time. Furthermore, it is observed whether a potential flame is extinguished or the polymer drips. Flammability Testing Equipment
What is Glow Wire Testing?
Historically a number of methods have been developed to evaluate material flammability and fire resistance. These include both direct flame and indirect flame testing methods. An example of the direct flame method is defined in the UL 94 specification. This long accepted test method involves applying a flame directly to a vertically or horizontally mounted specimen under controlled conditions. On the other hand, the indirect flame method features a non-flaming heat source applied to a sample. Glow wire testing is an example of the indirect flame method. Test results from applying these methods provide a way to compare the materials’ tendency to resist ignition, self-extinguish flames (should ignition occur), and to not propagate fire via dripping. To better understand the differences between the direct method and the indirect method, refer to Figure 2.
