Reaction-to-Fire Tests – Heat Release, Smoke Production and Mass Loss Rate – Part 1: Heat Release Ra...
Scope
This part of ISO 5660 specifies a method for assessing the heat release rate and dynamic smoke
production rate of specimens exposed in the horizontal orientation to controlled levels of irradiance with an
external igniter. The heat release rate is determined by measurement of the oxygen consumption derived
from the oxygen concentration and the flow rate in the combustion product stream…
