Furthermore, a
layer tissue paper located beneath the
specimen must not ignited glowing
particles falling from the specimen.
The specimen must positioned such that
the tip the glow-wire acts the surface
section the specimen (vertical surface of

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. Furthermore, layer tissue paper located
beneath the specimen must not ignited glowing particles falling
from the specimen.com

Technical Information
Tests and Testing Procedures per IEC/EN Standards (continued)
This test simulates flames that may arise under certain conditions (e.
As the highest temperature the event a
fault anticipated the contact insert/wire
connection, the tip the glow-wire must act
upon the section the insulation housing
that the closest this contact point., ten seconds).
Not only the ignition the test specimen resulting from intrinsic defect tested, but also its behavior when other parts ignite., 960°C/1760°F over sec-
onds, 850°C/1562°F over seconds) are
specified the standards.
However, the glowing conductor shall not
cause ignition the product involved (e.
In the event failure, high current may cause conductor glow., a
rail-mount terminal block). The test specimen exposed standard gas
flame during defined time period (e.g.wago.
The test passed there are visible
flames permanent glowing, flames or
glowing extinguish within seconds after
removal the glow-wire. For the glow-wire
test, the tip the glow-wire pressed
against surface the test specimen (see
picture).
.
After the test flame has been removed, the specimen must self-extin-
guish within seconds.g.g, fault current over creepage distance, overloading parts compo-
nents).21
