Flame-Propagation Testing of Wire and Cable
|Publication Date:||8 June 2006|
This standard provides a protocol for exposing cable samples to a theoretical 20 kW (70 000 Btu/h) flaming ignition source for a 20-min test duration. The test determines the flame propagation tendency of singleconductor and multi-conductor cables intended for use in cable trays
The purpose of this standard is to establish a test protocol and performance criteria to determine the flame propagation tendency of cables in a vertical cable tray.
