Knowing the properties of the plastics used in components and parts of your devices is essential to building a reliable, safe and high performance product.
We run tests to verify the characteristics of the plastics according to the following standards:
TRACKING TEST – EN 60695-2-12 “Fire hazard testing Part 2-12: Glowing/hot-wire based test methods – Glow Wire Flammability Index (GWFI) methods for materials. Part 2-12 covers the glow wire test when the wire is applied to specimens of solid insulating materials to determine the glow wire flammability index (GWFI).
The GWFI is the maximum test temperature, determined during the procedure defined in the standard according to the material being tested:
- it does not produce flames or they are extinguished within 30 seconds after the removal of the glow wire and the material is not completely consumed
- drips, if any, do not ignite the underlying sheet of paper.
GLOW TRACKING TEST – EN 60695-2-13 “Fire hazard testing Part 2-13: Glowing/hot-wire based test methods – Glow-wire flammability index (GWFI) test method for materials”.
Part 2-13, on the other hand, relates to the glow wire test to be applied to specimens of solid insulation material to determine the glow wire ignition temperature (GWIT). The
glow wire ignition temperature is the temperature 25 K (or 30 K) higher than the highest test temperature, determined during the procedure, at which the test material a) does not ignite, or b) if it does ignite, sustained, continuous burning does not last more than 5 seconds for each individual flame.
BALL PRESSURE TEST – EN 6069510-2 “Fire hazard testing Part 10-2: Abnormal heating – Ball pressure test method” The test verifies that the insulating materials used in the electrical equipment are heat resistant.
NEEDLE FLAME TEST: used to evaluate the flammability class of a plastic, simulating the effect of small flames on a test sample for a set time.
