This Part of EN 1366 specifies a method for determining the fire resistance of raised access floors and hollow floors when subjected to a fire from within the plenum beneath the floor. The fire exposure applied to the test specimen may be either:a) standard time temperature curve;b) 'reduced' time temperature curve which follows the standard time/temperature curve only up to 500 °C. After this temperature has been reached the temperature within the furnace is maintained at 500 °C.This document does not determine the fire resistance of the sub-floor on which the raised or hollow floor is constructed; this is given in EN 1365-2.
