ISO 834-10-2014 pdf free.Fire resistance tests – Elements of building construction – Part 10: Specific requirements to determine the contribution of applied fire protection materials to structural steel el ements.
This part of Iso 834 specifies a method for testing lire protection systems applied to structural steel members used in buildings as beams, columns, or tension members. This part of ISO 834 is intended for use in conjunction with the assessment protocol described in ISO 834-11. It applies to steel sections (including hollow sections) and only considers sections without openings in the web. Results from analysis of I or II sections are directly applicable to angles, channels, and T-sections for the same section factor, whether used as individual members, e.g. bracing, or part of a fabricated structural system such as a steel truss construction. This part of ISO 834 does not apply to solid bar, rod, or concrete-filled hollow sections.
This part of ISO 834 describes the fire test procedures that specify the tests which should be carried out to determine the ability of the lire protection system to remain sufficiently coherent and in position for a well-defined range of deformations, furnace, and steel temperatures, such that the efficacy of the fire protection system is not significantly impaired, and to provide data on the thermal characteristics of the fire protection system when exposed to the standard temperature/time curve specified in ISO 834-1.
In special circumstances, where specified in National Building Regulations, there can be a requirement to subject reactive fire protection materials to a smouldering curve. The test and the requirements for its use arc described in Annex.G.
This part of ISO 834 is applicable to both passive and reactive fire protection systems as defined in the terms and definitions, which are installed or applied in such a way that they remain in place for the intended duration of fire exposure.
The fire test methodology makes provision for the collection and presentation of data which is then used as direct input into 150 834-11 to determine the limits of direct application to steel sections of various shapes, sizes, and fire resistance periods.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 834-I. ISO 13943, ISO 8421-2. and the following apply.
3.1 characteristic steel temperature
temperature of the structural steel member which is used for the determination of the correction factor for stickabllity calculated as (mean temperature + maximum temperature)/2
3.2 design temperature
temperature of the steel member for structural design purposes
3.3 fire protection
protection afforded to the steel member by the fire protection system such that the temperature of the steel member is limited throughout the period of fire exposure
3.4 fire protection system
fire protection material together with any supporting system including mesh reinlorcemcnt as tested
Note ito entry: The reactive fire protection materials system includes the primer and top coat if applicable.
3.5 fire protection thickness
dry thickness oF a single-layer tire protection system or the combined thickness ot all layers oF a tire protection system
Note 1 to entry: The thickness of elements of the supporting system or joint cover strips are not included in the fire protection thickness.
Note 2 to entry: For reactive tire protection systems, the thickness is the mean dry film thickness ot the coating excluding primer and top coat if applicable.
3.6 H section steel member with wide flanges compared with the section depth whose main function is to carry axial loads parallel to its longitudinal axis which can be combined with bending and shear.ISO 834-10 pdf free download.
