Development of smoke corrosion and leakage current damage functions

Smoke damage functions have been developed for representative materials used in smoke sensitive facilities such as semiconductor fabrication cleanrooms or data centers. Leakage currents and corrosion rates, normalized with the total smoke deposition per unit surface area, are presented from the flaming combustion of polycarbonate, PVC and Nylon. When coupled with smoke deposition rates, these damage functions can be used to assess expected damage levels for specific fire scenarios.
