Insulated Conductors and Cables for Installations NF C 32-070

摘要

For many years the problem of the behavior of electrical conductors and cables in the presence of fire has often arisen in connection with the most diverse circumstances, when it becomes a matter of investigating the causes of disasters or of avoiding them, or indeed of implementing effective means of limiting their destructive effect. The numerous data gathered on these occaisons as well as the results of the many studies carried on at the same time for the purpose of improving the behavior of conductors and cables toward fire have yielded a relatively exaact picture of the material requirements and have permitted specifying tests by which conductors and cables can be judged from this point of view. The purpose of the present standard is to list the test methods recognized in the field and to define them so as to arrive at a reliable classification of conductors and cables and permit a choice as a function of the requirements of fire safety and the conditions of installation.
