This part of ISO 10294 gives guidance on the application of the test method specified in ISO 10294-1:1996.

This test method is concerned with the assessment of a fire damper to prevent the spread of fire and hot gases from one compartment to another. It is not intended for dampers used only in smoke control systems.

It is applicable to fire dampers included in an air distribution system.

The test is not designed to test fire protection devices which only deal with air transfer applications, or when a damper is used in suspended ceilings as the installation of the damper and duct may have an adverse effect on the performance of the suspended ceiling and other methods of evaluation may be required.
