Description / Abstract:
This Standard specifies a method for testing fire protection
systems applied to structural steel members, used in buildings as
beams, columns or tension members. The Standard 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 H 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 standard
does not apply to solid bar, rod or concrete filled hollow
sections.
This Standard describes the fire test procedures, that specify
the tests which, should be carried out to determine the ability of
the fire 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 is described in Annex G.
The standard 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
ISO834-11 to determine the limits of direct application to steel
sections of various shapes, sizes and fire resistance periods.
