Review of Literature, Applicable Test Methods, and Incident Data for the Evaluation of the Fire Performance of Central Telephone Office Equipment

摘要

At the request of the Rural Electrification Administration, a program was initiated to evaluate the adequacy of current flammability specifications for electrical equipment used in telephone company central offices. The high reliance on telephone services for emergency communications necessitates that measures be considered to minimize the likelihood of fire related interruptions of service. This report provides a review of current test methods and specifications for central office equipment; a review of available fire test methods in various categories; a brief literature review of relevant fire research and fire testing of wiring, cables, and assemblies; and a review of fire incident data.
