There are enormous differences between flame retardant cables and fire resistive cables.
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.
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.
The title of iec 60331 is test for electric cables under fire conditions circuit integrity.
But of course we have to learn more than that.
Oxygen barrier cable also known as highly flame retardant cable.
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.
In term of cable construction it is essential to distinguish the outer sheath colour between flameretardant cable and fire resistant cable.
The biggest difference between flame resistant and flame retardant fabrics lies in how each is made.
Difference between flame retardant cable and fire resistant release time 2016 05 27 14 43 hit.
Without a special chemical application a fabric will not qualify as flame retardant.
Due to relative low cost fire retardant cables are widely used as fire survival cables.
The main code as follow.
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.
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.
Commonly fire resistant cable has red outer sheath jacket while flame retardant may have grey or black outer sheath jacket.
Fire resistant cables are often used to maintain circuit integrity of those vital life safety systems such as fire alarm and suppression services.
Iec 60322 fire resistant.
For iec 60322 is test on electric cable under fire conditions.
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.
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.
Flame retardant cables are designed to resist the spread of fire into a new area.
