scope:

This standard describes test fires to which fire detectors are to be subjected in order to satisfy the conditions specified in other parts of EN 54. The fire sensitivity tests are intended to supply information as to the response behaviour to be expected from fire detectors under genuine fire conditions. For this purpose, the detectors to be tested are subjected to test fires, which are typical of certain categories of fire and, viewed as a whole, cover the majority of the fir es which occur in practice. On the basic of the test result, the sensitivity of a type of detector is assessed with regard to its response behaviour under specific fire conditions. The test fires are so arranged that characteristic fire size curves are produced in the desired manner. The fuel used serves this purpose both qualitatively and quantitatively.
