scope:

This standard applies to fire door assemblies and to components used in fire door assemblies.

The fire exposure used in this standard is not representative of all fire conditions which may vary with changes in the fire loading, ventilation and configuration, compartment size and heat sink characteristics of the compartment which contains the fire.

Similarly, the hose stream exposure is not intended to be representative of actual hose streams used by fire fighters during suppression efforts as these too can vary.

The test methods in this standard shall not be used to provide the following:

a) Full information regarding the performance of specific fire door assemblies installed in fire resistive barriers constructed of materials other than those tested.

b) An evaluation of the degree to which the fire door assembly contributes to the hazards by the generation of smoke, toxic gases or other products of combustion.

c) Measurement of a fire door assembly's ability to control or limit the passage of smoke or similar products of combustion.

d) A temperature transmission limitation to the unexposed surface of the fire door assembly.

e) Measurement that determines a limit on the number and size of vision panels permitted or the number and size of lateral openings permitted between the door and any frame.

f) The degree or hourly rating of protection required to protect an opening.

g) Requirements for items attached to, or used in conjunction, with fire doors assemblies that serve the purpose, or act, as hold open or release devices.

h) Test requirements for other types of detection devices that can be used with various fire door assemblies or where such detection devices are to be located except as stated in this document.

This standard states performance requirements for fire door accessories that incorporate items that serve to function as self-closing, automatic closing or testing devices. This includes, but is not limited to, power operators, chain hoist assemblies and other testing devices that, when used in conjunction with a fire door assembly, initiate automatic closing or cause or allow the fire door assembly to attain the fully closed position.

The performance requirements shown in this standard shall be considered to be the minimum requirements. Additional testing above and beyond what is stated in this standard shall be permitted in order to satisfy other national or international jurisdictional requirements.

Purpose

This standard states the specific fire, hose stream and other performance test and certification requirements used in evaluating fire door assemblies.

The degree of fire protection measured provides a period of time in which a fire door assembly will remain in the opening and retard the passage of fire as measured in the form of flames, heat and hot gases.
