In term of cable construction it is essential to distinguish the outer sheath colour between flameretardant cable and fire resistant cable.
Difference between flame retardant and fire resistant cables.
The biggest difference between flame resistant and flame retardant fabrics lies in how each is made.
For iec 60322 is test on electric cable under fire conditions.
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.
Fire resistant cables are often used to maintain circuit integrity of those vital life safety systems such as fire alarm and suppression services.
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.
Oxygen barrier cable also known as highly flame retardant cable.
The main code as follow.
The title of iec 60331 is test for electric cables under fire conditions circuit integrity.
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.
Similarly without being made of certain nonflammable fibers a fabric will not quality as fire resistant.
Flame retardant cables are designed to resist the spread of fire into a new area.
Commonly fire resistant cable has red outer sheath jacket while flame retardant may have grey or black outer sheath jacket.
Due to relative low cost fire retardant cables are widely used as fire survival cables.
Without a special chemical application a fabric will not qualify as flame retardant.
It s about the test code.
Iec 60322 fire resistant.
There are enormous differences between flame retardant cables and fire resistive cables.
Iec 60332 1 bs 4066 1 flame test on single vertical insulated wires cables.
Difference between flame retardant cable and fire resistant release time 2016 05 27 14 43 hit.
But of course we have to learn more than that.
This article below will describe the differences between flame retardant and fire rated cables.
