scope:

This part of EN 1364 specifies a method for determining the fire resistance of ceilings, which in themselves possess fire resistance independent of any building element above them. This Standard is used in conjunction with EN 1363-1. The method is applicable to ceilings, which are either suspended by hangers or fixed directly to a supporting frame or construction, and to self-supporting ceilings. Within this test method, the ceiling is exposed to fire, with the exposure being applied either: a) from below the ceiling, or b) from above the ceiling to simulate fire within the cavity above the ceiling. The contribution to fire resistance which a suspended ceiling might provide as a protective membrane to loadbearing elements is determined using the procedure given in EN 13381-1.
