ISO 5660-1 specifies a method for assessing the heat release rate and dynamic smoke production rate of specimen 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. The time to ignition (sustained flaming) is also measured in this test.

The dynamic smoke production rate is calculated from measurement of the attenuation of a laser light beam by the combustion product stream. Smoke obscuration is recorded for the entire test, regardless of whether the specimen is flaming or not.

This part of ISO 11925 specifies a method of test for determining the ignitability of products by direct small flame impingement under zero impressed irradiance using vertically oriented test specimens.

Information on the precision of the test method is given in Annex A.

This document specifies requirements for the construction and performance of residential sprinklers as well as test methods for their type approval, which are operated by a change of state of an element or bursting of a glass bulb under the influence of heat, for use only in automatic sprinkler systems for domestic and residential applications as defined in EN 16925:−1.

This standard does not cover representative fire and other tests for special sprinklers that are intended to provide for specific fire hazards, nor does it cover fire and other tests for sprinklers for commercial and industrial sprinkler systems as in EN 12845. Those test requirements are covered by EN 12259-1.

NOTE 1 All pressure data in this European Standard are given as gauge pressures in bar.

NOTE 2 Sprinklers according to EN12259-1 can also be used in residential and domestic applications if the system is designed according to EN 12845.

This European Standard specifies product characteristics, and test/assessment methods and compliance criteria of the test results for smoke barriers which comprise the barrier itself, with or without associated activation and drive devices. It does not cover barriers made of part of the building’s structure. Smoke barriers are intended to be installed in smoke control systems in construction works.
