Vertical flame spread test AF/R category
1 Scope
This document describes the Type AF/R test method for evaluating the vertical flame suppression of vertically installed bundled wires and cables under specified conditions.
ability to spread.
This document applies to power cables with conductor cross-section greater than 35mm2.The cables are installed at intervals in front of and behind the test steel ladder, so as to
The total nominal volume of non-metallic materials contained in the sample is 7L/m. The fire time is 40min. This installation method is used in the cable specification
Special cables for use in special installations are required. Type AF/R is not suitable for ordinary cables.
This test is used for type approval test. See Appendix A for the selection requirements of the test cables. The extent of damage to the flame spread through the cable specimen
to measure. This test procedure can be used to verify the ability of a cable to suppress the spread of flames.
Recommended performance requirements are given in Appendix B.
Note. The term "wire and cable" in this document includes all metal conductor insulated cables used for power or signal transmission.
