Design Parameters for Stack-mounted Light Extinction Measurement Devices

Résumé du livre

The light attenuation characteristics of the smoke produced by fire are commonly measured in both fire experiments and standard fire tests. The results of these measurements are traditionally used for building and fire code regulatory purposes, design and testing of fire detectors, advanced material development, and life safety calculations. In addition, recent research suggests that for various fuels burning in over-ventilated fires, light extinction measurements may be used for the determination of the mass concentration of smoke per unit volume and smoke yield. The methods used for measuring light extinction in various fire tests and experiments are not consistent, however, and frequently do not take into account previously determined sources of uncertainty.
