Difference Between Flame Retardant And Fire Resistant Cables

It s about the test code.

Difference between flame retardant and fire resistant cables.

Flame retardant cables are designed to resist the spread of fire into a new area. Iec 60322 fire resistant. For iec 60322 is test on electric cable under fire conditions. In term of cable construction it is essential to distinguish the outer sheath colour between flameretardant cable and fire resistant cable.

The title of iec 60331 is test for electric cables under fire conditions circuit integrity. Similarly without being made of certain nonflammable fibers a fabric will not quality as fire resistant. A fire resistant cable will continue to function in the event of a fire and is also identified as a circuit integrity cable a flame retardant cable on the other hand will not propagate or convey a fire. Due to relative low cost fire retardant cables are widely used as fire survival cables.

Iec 60332 1 bs 4066 1 flame test on single vertical insulated wires cables. A flame resistant cable in this manner would let the circuit stay in operation allowing power to be transferred through it while this would not be the case with a flame retardant cable. The biggest difference between flame resistant and flame retardant fabrics lies in how each is made. This article below will describe the differences between flame retardant and fire rated cables.

A layer of non melting non flammable halogen free smoke free fire resistant plastic material is filled or wrapped between the cable insulated core and the cable sheath i e insulating organic is used to isolate the cable from the outside oxygen gas so that the cable is non. Fire resistant cables are often used to maintain circuit integrity of those vital life safety systems such as fire alarm and suppression services. Difference between flame retardant cable and fire resistant release time 2016 05 27 14 43 hit. The main code as follow.

Commonly fire resistant cable has red outer sheath jacket while flame retardant may have grey or black outer sheath jacket. Without a special chemical application a fabric will not qualify as flame retardant. Fire and disaster planning is painstaking so it is of the utmost importance that specifiers and contractors understand when to use flame retardant and when to use fire resistant cable what the differences are and how the right choices should be arrived at. Oxygen barrier cable also known as highly flame retardant cable.

There are enormous differences between flame retardant cables and fire resistive cables. But of course we have to learn more than that.
