This document specifies the apparatus and procedure for measuring reaction to fire behaviour underreduced oxygen atmospheres. Continuous measurements are made to calculate heat release rates,smoke and specific gas production rates, and mass loss rates. Ignition time measurements are alsomade and ignition behaviour is obtained. Pyrolysis parameters of specimens exposed to controlledlevels of irradiance and controlled levels of oxygen supply can be determined as well.Cross References:ISO 5660-1:2015ISO 13927:2015ISO 13943
