Flame Retardance
1. Flame retardance in accordance with EN 60332:2004
EN 60332:2004 Tests on electrical and optical cables under fire conditions. The standard applies to single
insulated wires (cables) and requires a vertical flame test with a maximum flame climb of 450mm. The test lasts
between 1 and 8 minutes, depending on the cable diameter.
EN 60332-1-1:2004 / BS EN 60332-1-1:2004 / IEC 60332-1-1:2004 / DIN EN 60332-1-1:2004 / VDE 0482-1-
1:2005-06 Test on electrical and optical cables under fire conditions. Test for a vertical flame propagation fo a
single insulated wire or cables.
EN 60332-1-2:2004 / BS EN 60332-1-2:2004 / IEC 60332-1-2:2004 / DIN EN 60332-1-2:2004 / VDE 0482-1-
2:2005-06 / CEI 60332-1-2( CEI 20-35/1-2 ) Tests on electrical and optical fiber cables under fire conditions. Test
for a vertical flame propagation for a single insulated wire or cable – Procedure for 1kW premixed flame.
This standard specifies a method of test for resistance to vertical flame propagation for a single insulated wire or
cable. Part 1-1 specifies the test apparatus and Part 1-2 specifies the test procedure. The cable sample is
deemed to pass the test if the distance between the lower edge of the top support and the nset of charring is
greater than 50mm. In addition, a failure shall be recorded if burning extends downward to a point greater than
540mm from the lower edge of the top support.
EN 60332-1-2:2004 specifies the use of 1kW premix flame and is for general use, except that the procedure may
not be suitable for the testing of small insulated conductors or cables of less than 0.5mm sq cross section
because the conductor melts before the test is completed, or for the testing of small optic fiber cables because
the fiber will be broken before the test is completed. In this case, the procedure given by EN 60332-2-1/2 is
recommended.

0482-2-2:2005-06 / CEI 60332-2-2 (CEI 20-35/2-2) Test on electric and optical fiber cables under fire conditions.
Tests for vertical flame propagation for a single small insulated wire or cable. Procedure for diffusion flame.
This test applies to small dimensions cables.
This standard specifies a method of test for resistance to vertical flame propagation for a single insulated wire or
cable. Part 2-1 specifies the test apparatus and Part 2-2 specifies the test procedure.
