Hot Wire Ignition test is a type of resistance test to fire for plastic
materials. Heating wire is winded around the test sample and the wire
is heated up with a DC-current until it glows to see if the test sample
ignites. Please note that most new standards require the use of AC
current. (See Hot Wire Ignition Tester Model 4670 and 4680 for ACcurrent)

The Hot Wire Ignition Tester Model 4610 is a manual version. It
contains a DC-source, and observations, timing and calculations are
done manually.
Technical specification
• The test sample is sourced by DC power
• Holders for the test sample
• Digital A- and V-meters
• Clips for Voltage measurement at calibration
• Terminals to connect the element wire
• Heating wire 80% Nickel and 20% Chromium – 150 m included
Optional – Cabinet
• Cabinet 0,5 m3
 according to requirement of
standard
• Transparent door – access holes to operate
without opening the door
• Fan blow out gases from cabinet after
testing
Optional – Winding device
• Helps to wind up the wire onto the test
sample with 6,3 mm pitch
• Clamps for test sample
• Weight for wire tension
