This Standard specifies the performance requirements of cables when exposed to fire with respect to specific characteristics and allocates a classification. The Standard specifies the criteria for tests that may be in addition to those requirements specified in relevant cable Standards.This Standard does not address issues with respect to cables initiating or being the cause of fire.Wiring system circuit integrity (WS) is covered by AS/NZS3013 and is an additional and separate cable requirement.This Standard classifies the following characteristics:(a) Reduced flame propagation (RFP).(b) Reduced hazardous effects (RHE).(c) Cable circuit integrity (CI).NOTE:1 For purchasing guidelines, see Appendix A.2 Although this Standard specifies cable characteristics under defined fire conditions, it cannot be assumed that cables would behave in the same manner in a real fire. For example, the propagation of the flame along a cable installation is influenced by a number of factors independent of the cable itself, such as—(a) the volume of combustible material exposed to the fire and to any flame which may be produced by the combustion of the cables;(b) the geometrical configuration of the cables and their relationship to any enclosure;(c) the rate of temperature rise and the peak fire temperature which influence the ignition of gases emitted from the cables;(d) the volume of air passing through the cable installation; (e) installation conditions (on ladders or trays, in conduit);(f) vertical or horizontal installation; and(g) fire quenching techniques at the installation (water sprinkler, gas suppression).
