IEC60950-1 Hot Wire Ignition Tester, Annealing Time 8s-12s, Power 0.26W/mm±4%
M.1 Hot wire ignition test
M.1.1
Five samples of each material shall be tested. The samples shall be 1 50 mm long by 1 3 mm wide, and of uniform thickness stated by the material manufacturer.
Edges shall be free from burrs, fins, etc.
M.1.2
A (250 ± 5) mm length of nichrome wire (80 % nickel, 20 % chromium, iron free) approximately 0,5 mm diameter and having a cold resistance of approximately 5,28 Ω /m shall be used. The wire shall be connected in a straight length to a variable source of power which is adjusted to cause a power dissipation of 0,26 W/mm in the wire for a period of 8 s to 1 2 s.
After cooling, the wire shall be wrapped around a sample to form five complete turns spaced 6 mm apart.
M.1.3
The wrapped sample shall be supported in a horizontal position and the ends of the wire connected to the variable power source, which is again adjusted to dissipate 0,26 W/mm in the wire (see Figure M.1 ).
M.1.4
Start the test by energizing the circuit so that a current is passed through the heater wire yielding a linear power density of 0,26 W/mm.
M.1.5
Continue heating until the test specimen ignites. When ignition occurs, shut off power and record time to ignite.
Discontinue the test if ignition does not occur within 1 20 s. For specimens that melt through the wire without ignition, discontinue the test when the specimen is no longer in intimate contact with all five turns of the heater wire.
M.1.6
The test shall be repeated on the remaining samples.
M.1.7
The average ignition time and the thickness of each set of specimens shall be recorded.
Standard:IEC60950-1 ,IEC60947-1:2011,IEC60695-2-20. Flammability Testing Equipment
Application:It is suitable for electric and electronic products, household appliance materials to do ignition dangerous test. It simulates the heat source or ignition source of simulates glow component and overload resistance which may cause thermal stress in a short time.
Test sample:Information technology equipment, low voltage switch and control equipment parts. Flammability Testing Equipment
Feature:Hot-wire coil ignition test adopts the specific size (ф0.5mm length:250mm) and specific material (Ni80/Cr20) of heater strip which is pre-annealed with required heating power(0.26W/mm) and time (8s～12s). Then coil heater strip on the specimen for 5 cycles according to certain wire wrapping tension (5.4N) and certain wire wrapping distance (6.35mm). Next, take the specimen with wrapping heater strip to test until 120s under the stipulate heating power (0.26W/mm) the users can judge the fire risk according to whether the specimen ignite and the ignite time.
