NFPA 287 – Standard Test Methods for Measurement of Flammability of Materials in Cleanrooms Using a Fire Propagation Apparatus (FPA)

۲۰۲۲ Edition

Chapter 1 Administration

۱-۱ Scope.

۱-۱-۱ This standard shall determine and quantify the flammability characteristics of materials containing polymers that are used in cleanroom applications.

۱-۱-۱-۱ The propensity of these materials to support fire propagation, as well as other flammability characteristics, are quantified by means of a fire propagation apparatus.

۱-۱-۱-۲ Measurements obtained include time to ignition (t_ign) chemical (Q_chem) , and convective (Q_c) heat release rates, mass loss rates (m) , and smoke extinction coefficient (D) .
