BS EN 1365-3:2000 specifies a method for determining the fire resistance of beams with or without applied fire protection systems and with or without cavities. This standard is used in conjunction with EN 1363-1.
Beams which are part of a floor construction are tested with the floor construction as described in EN 1365-2 and are subject to evaluation of integrity and insulation.
General guidance on this method of test is given in Annex A.
