This document specifies a test method for the determination of the resistance of fire dampers to heat, and for the evaluation of their ability to prevent fire and smoke spreading from one fire compartment to another through an air distribution system.

This part of ISO 21925 describes the test requirements related to intumescent fire dampers. It is intended for intumescent fire dampers that are expected to be classified as EI dampers. Without the addition of a mechanical damper, they are unable to achieve the “S” classification, which includes a leakage limit imposed at ambient temperature.

It is not intended to be used for dampers used only in smoke control systems, for testing fire protection devices which only deal with air transfer applications, or for dampers used in suspended ceilings, as the installation of the damper and duct can have an adverse effect on the performance of the suspended ceiling, requiring other methods of evaluation.

NOTE "Air transfer" is a low-pressure application through a fire separation door (or wall, floor) without any connection to an air duct.

This standard test methodology and resulting field of direct application is applicable to linear joint fire seal materials used to seal around fire door sets which have been tested to ISO 3008-1.

This test methodology uses a smaller scale fire resistance furnace than that prescribed in ISO 3008-1.

ISO 20710-1, Part 1, provides information on the goal, scope, structure, contents, and background of the different parts of ISO 20710. The purpose of the series of ISO 20710 documents is to give information on the active fire protection systems in the design, implementation, and maintenance described in ISO 23932-1. ISO 20710 is linked to the steps of the performance-based fire safety engineering design process described in ISO 23932-1.

This International Standard is not intended as a detailed technical design guide but is intended to provide the guidance necessary to use ISO 20710 for professionals who consider the active fire protection systems at each step presented in ISO 23932-1.
