Revised by IEEE Std 1202-2006 A test protocol and the performance criteria to determine the flame propagation tendency of cables in a vertical cable tray are established. It applies to single insulated and multiconductor cables. The test consists of exposing cable samples to a theoretical 20 kW (70 000 Btu/hr) flaming ignition source for a 20 min duration. The test facility, test sample requirements, test procedure, and evaluation of results are covered.

IEEE Std 1137-1991 provides guidance for controlling or modifying the inductive environment and the susceptibility of affected wire line telecommunications facilities in order to operate within the acceptable levels of steady-state or surge induced voltages of the environmental interface (probe wire) defined by IEEE Std 776-1987 (Guide for Inductive Coordination of Electric Supply and Communications Lines). Procedures for determining the source of the problem are given. Mitigation theory and philosophy are discussed, and mitigation devices are described. The application of typical mitigation apparatus and techniques and installation, maintenance, and inspection of mitigation apparatus are addressed. Advice for determining the best engineering solution is offered, and general safety considerations are discussed.
