Technical Information
Tests and Testing Procedures per IEC/EN Standards (continued)
This test simulates flames that may arise under certain conditions (e.g.
In the event failure, high current may cause conductor glow., ten seconds).
Material Tests
All WAGO products meet requirements for the following material tests:
• Needle Flame Test per IEC/EN 60947-7-1, IEC/EN 60695-11-5
• Glow-Wire Test per IEC/EN 60998-1, IEC/EN 60695-2-11
Flames must not fuelled the insulation materials used, thus cre-
ating larger fire. The test specimen exposed standard gas
flame during defined time period (e. Furthermore, a
layer tissue paper located beneath the
specimen must not ignited glowing
particles falling from the specimen. For the glow-wire
test, the tip the glow-wire pressed
against surface the test specimen (see
picture).
However, the glowing conductor shall not
cause ignition the product involved (e.
After the test flame has been removed, the specimen must self-extin-
guish within seconds.g, fault current over creepage distance, overloading parts compo-
nents)
