Many fires that occur now have electrical causes. In many cases, they are related to overloads and short circuits in connectors, electrical appliances, or even poorly designed and manufactured pipelines. When a fire occurs, the fire behavior of cables is an important factor in ensuring the safe evacuation of personnel.
Zero risk does not exist, but its impact may be minimized. Therefore, fire performance testing is a standard requirement that has been included in the rules and legislation of the construction and transportation departments in many countries around the world.
Reaction to fire test
The laboratory is fully equipped and can conduct the main fire performance tests defined below
International standard: IEC 60332-1-2 Vertical flame propagation: These tests verify the procedures for vertical flame propagation and determination of flame droplets/particles.
IEC 60332-3-21/22/23/24/25 Flame propagation: These tests verify the propagation of flames when cables come from external fires. In this case, the flame is applied to a group of vertically placed cables and is coupled with the force of ventilation. After applying the flame, the cable must be able to limit propagation to self extinguishing.
IEC 61034-2 Smoke Density: This test verifies the opacity of smoke when cables burn. For a section of cable placed in a 27m3 room, it is necessary to apply a flame containing alcohol and measure its transmittance.
IEC 60754-1/2: Gases generated during combustion of cable materials: This test verifies the gases generated during combustion. After chemical analysis, determine its halogen content, acidity (measured by pH value), and conductivity.
Fire test
UL 2196 Cable Fire Resistance Test: Used to verify the integrity of cables in the event of a fire. The purpose of doing so is to maintain the functionality of the cable even when exposed to a fire. Then complete the test through hose flow testing.
Fire resistance of DIN 4102-12 cable system to maintain circuit integrity
EN 1366-11 Fire protection systems for cable systems and related components
EN 50577 cables. Flame resistance test for unprotected cables (P level).
On the other hand, the laboratory can also test cables according to the following standards:
UL 758 Standard for Wiring Materials for Household Appliances
ISO 6722 Road Vehicles. 60V and 600V single core cables.
UL 1581 Electrical Reference Standard. Wires, cables, and flexible cords.
NF C 32-070 Test 1 (Class C2) Vertical flame propagation test.
