ISO834-6 Fire Test to Building Material –Standard
ISO 834-6 Fire-resistance tests-Elements of building construction-Part 6: Specific requirements for loadbearing beams 

ISO834-6 Fire Test to Building Material –Scope
This part of ISO 834 specifies the procedures to be followed for determining the fire resistance of beams, when tested on their own.
Beams are normally tested with their underside and two vertical sides fully exposed to heating. However, when the exposure is from four sides or less than three sides, appropriate exposure conditions are necessary. Beams which are part of a floor construction are tested with the floor construction as described in ISO 834-5 and are subject to evaluation of integrity and insulation.
