Material Tests

All WAGO products meet requirements for the following material tests:
• Needle Flame Test per IEC/EN 60695-11-5

This test simulates flames which may result under certain conditions (for example, a fault current over a creepage distance, over-
loading of ports or components). Nearby parts can also be affected by such flames.
Not only is the ignition of the test specimen resulting from an intrinsic defect tested, but also its behavior when other parts are
ignited.

Flames must not be fuelled by the insulation materials used,
thus creating a larger fire. The test specimen is exposed to a
