Flame Propagation Test for a Single Insulated Cable
Compliance
IEC 60332-1, IEC 60332-3-24
The Flame Propagation Test Apparatus, in accordance with IEC 60332, provides a test procedure for testing the resistance to vertical flame for a single vertical electrical insulated conductor, cable, or optical fiber cable, under a 1 kW pre-mixed flame.
The procedure of Flame Propagation Test for a Single Insulated Cable:
a) A piece of single insulated cable with a length of 600mm, is mounted vertically.
b) Stabilize the ignition source as per IEC 60695-11-2, adjust the burner angle to 45 degrees.
c) Impinge the flame to the insulated cable, at a distance of 475mm.
d) Observe and remove the flame after the specific flame application time.
e) Repeat two more tests.
f) Evaluate the test results.
