Flammability and toxicity testing of wire and cable

New testing requirements are being developed and implemented to measure the flame propagation characteristics of tray cables and the toxic gases generating during combustion of wire and cable. The author provides an overview of the organizations developing the tests, a general description of the test protocols, the current status, and the potential impact on the pulp and paper industry. It is noted that the establishment of new flame testing criteria for tray cables may eliminate some cable constructions presently used in cable tray. The introduction of new materials that either are more flame retardant, produce less smoke, or generate less toxic gas provides opportunities for new construction and products.<
