The assessment detailed in this Part 11 is designed to cover a range of thicknesses of the fire protection material, a range of steel sections characterised by their section factors, a range of design temperatures and a range of valid fire resistance classification periods. This standard covers fire protection systems that include both passive (boards, mats, slabs and spray materials) and reactive materials as defined in this document. The assessment procedure is used to establish: a) On the basis of the temperature data derived from testing loaded and unloaded specimens, a correction factor and practical constraints on the use of the fire protection system (the physical performance); b) On the basis of the temperature data derived from testing unloaded short steel specimens, the thermal properties of the fire protection material, (the thermal performance). The limits of applicability of the results of the assessment are defined together with permitted direct application of the results to different steel section sizes and strength grades (but not stainless steels) and to the fire protection system tested. The results of the tests obtained according to ISO 834 10 and the assessment in this Part 11 are directly applicable to steel sections of "I" and "H" cross-sectional shape and hollow sections. Results from analysis of I or H sections are directly applicable to angles, channels and T-sections for the same section factor, whether used as individual elements, or, as part of a fabricated steel truss.. The results of the assessment are applicable to fabricated sections. The standard does not apply to concrete filled hollow sections, beams or columns containing holes or openings of any type, or, solid bar. Any assessment method is acceptable provided it meets the acceptability criteria given in 5.5. Examples of assessment methods in common use are given in Annexes C to G.
