2. Fire reaction of cables
2.1 Old French system
Standard NF C32-070 sets out the principles for classifying cables according to their fire behavior, including C1 and C2 classifications. Category C1 cables must demonstrate superior resistance to flame propagation, and must not release volatile flammable products in quantities sufficient to create a secondary ignition source. They must pass specific tests, including a vertical flame test on insulated cable (test no. 1) and an additional test (test no. 2) using a cylindrical furnace...
