ISO 834-10:2014 specifies a method for testing fire protection systems applied to structural steel members used in buildings as beams, columns, or tension members. It 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. ISO 834-10:2014 does not apply to solid bar, rod, or concrete-filled hollow sections. ISO 834-10:2014 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 are described in ISO 834-10:2014 (Annex G). ISO 834-10:2014 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 ISO 834‑11 to determine the limits of direct application to steel sections of various shapes, sizes, and fire resistance periods.
Abstract
Overview
ISO 834-10:2014 - Fire resistance tests - Elements of building construction - Part 10 - specifies test methods to determine the contribution of applied fire protection materials to structural steel elements. It defines how to measure the thermal performance and physical integrity of passive and reactive fire protection systems (coatings, wraps, insulation) applied to steel beams, columns, and tension members when exposed to the ISO standard temperature/time furnace curve (ISO 834-1). Test outputs feed directly into the assessment protocol of ISO 834-11 to establish applicability across section shapes and fire resistance periods.
Key topics and technical requirements
- Scope and applicability
- Applies to steel sections (including hollow sections) without web openings; excludes solid bar, rod, and concrete-filled hollow sections.
- Results from I- and H-sections can be extended to angles, channels, and T-sections with the same section factor.
- Test objectives
- Measure thermal characteristics (steel temperature rise) and determine whether the fire protection system remains coherent and in position under defined deformations, furnace, and steel temperatures.
- Provide data to assess efficacy for specified fire resistance periods.
- Test equipment & instrumentation
- Prescribed furnace exposure (ISO 834-1 temperature/time curve), thermocouples on steel, furnace temperature and pressure measurement, deformation and load monitoring.
- Specimens and installation
- Guidance on specimen design, preparation, conditioning, and installation for loaded and unloaded beams and columns.
- Reactive systems and smouldering
- Provision for reactive fire protection materials and, where required by national regulation, testing to a smouldering (slow heating) curve (informative annex).
- Data presentation
- Requirements for collecting and presenting test data so it can be used by ISO 834-11 to set limits of direct application.
Practical applications - who uses ISO 834-10:2014
- Fire protection product manufacturers (intumescent coatings, cementitious sprays) for performance validation and product development.
- Test laboratories conducting fire resistance and product certification tests.
- Structural and fire engineers evaluating fire-resistant designs and specifying protection thicknesses for steel members.
- Regulators and code authorities using standardized test data to set acceptance criteria and link to building regulations.
- Contractors and specifiers ensuring installed passive or reactive systems meet tested performance.
