DIN EN 60332-1-2:2004 vertical flame propagation for a single insulated wire or cable
DIN EN 60332-1-2:2004 Tests on electric and optical fibre cables under fire conditions—Part 1-2: Test for
vertical flame propagation for a single insulated wire or cable—Procedure for 1 KW pre-mixed flame and is for
general use, except that the procedure specified of less than 0.5mm2 total cross-section because the conductor
melts before the test is completed, or for the testing of small optical fibre cables because the cable is
broken before the test is completes. In these cases, the procedure giver in DIN EN IEC 60332-2-2 is
recommended.
Description of test method
The test sample shall be a piece of single insulated conductor or cable (600± 25)mm long.
The single insulated conductor or cable shall pass the test if the distance between the lower edge of the top
support and the onset of charring is greater than 50 mm.
In addition, a failure shall be recorded if charring extends downwards to a point greater than 540 mm from the
lower edge of the top support.
If a failure is record, two more tests shall be carried out ,if both tests result in passes, the single
insulated conductor or cable shall be deemed to have passed the test.
Other standard:
DIN EN 60332-2-2:2004 Tests on electric and optical fibre cables under fire conditions Part 2-2: Tests for
vertical flame propagation for a single small insulated wire or cable procedure for diffusion flame.
