Difference Between Flame Retardant And Fire Resistant Cables

Typically flame retardant cables resist the spread of fire into a new area whereas fire resistive cables maintain circuit integrity and continue to work for a specific time under defined conditions.

Difference between flame retardant and fire resistant cables.

Flame retardant cables are designed to resist the spread of fire into a new area. In term of cable construction it is essential to distinguish the outer sheath colour between flameretardant cable and fire resistant cable. 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. Fireproof wire and cable is a general name for the fire resistance wire and cable usually divided into flame retardant wire and cable zr bv and fire resistant wire and cable nh bv.

Iec 60332 1 bs 4066 1 flame test on single vertical insulated wires cables. Oxygen barrier cable also known as highly flame retardant cable. But of course we have to learn more than that. 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.

Similarly without being made of certain nonflammable fibers a fabric will not quality as fire resistant. This article below will describe the differences between flame retardant and fire rated cables. Commonly fire resistant cable has red outer sheath jacket while flame retardant may have grey or black outer sheath jacket. Difference between flame retardant cable and fire resistant release time 2016 05 27 14 43 hit.

Iec 60322 fire resistant. Due to relative low cost fire retardant cables are widely used as fire survival cables. The main code as follow. The biggest difference between flame resistant and flame retardant fabrics lies in how each is made.

Fire resistant cables are often used to maintain circuit integrity of those vital life safety systems such as fire alarm and suppression services. It s about the test code. 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. There are enormous differences between flame retardant cables and fire resistive cables.

For iec 60322 is test on electric cable under fire conditions. Flame retardant cables can resist the spread of fire but fire rated cables maintain circuit integrity and continue to work in the presence of fire.
