Full title and description

ISO 834-7:2000 — Fire-resistance tests — Elements of building construction — Part 7: Specific requirements for columns. This part of ISO 834 specifies procedures for determining the fire resistance of columns tested on their own, including guidance for reproducing exposure conditions when columns are exposed on fewer than four sides and requirements for extended application analyses.

Abstract

Specifies the test arrangement, furnace exposure, observations, performance criteria and reporting requirements for column specimens subjected to standard fire exposure. General guidance and commentary on application of test results are provided in an annex; the document also references ISO/TR 12470 for extended application analyses. The 2000 edition has been withdrawn and a revised edition (ISO 834-7:2025) was published subsequently.

• Edition / version: Edition 1 (2000).
• Number of pages: 9.

Scope

Defines the procedures to determine the fire resistance of individual columns when tested by exposing the relevant faces to furnace heating. It covers typical test arrangements, how to reproduce non‑four‑sided exposures encountered in practice, observables (loadbearing capacity, integrity, insulation where applicable), and the use of extended application analysis for untested forms of construction.

Key topics and requirements

• Test specimen configuration and furnace exposure for columns (including full‑side and reduced‑side exposure conditions).
• Measurement and observation requirements during the test (temperatures, deformations, structural behaviour, integrity checks).
• Performance criteria and expression of test results for fire resistance (criteria for failure and reporting).
• Requirements and guidance for extended application analysis when transferring results to untested forms of construction (reference to ISO/TR 12470).
• Note on revision: the 2025 edition introduces clarified testing methods (including method distinctions for loaded vs. unloaded/protected steel columns) and updates which supersede the 2000 edition.

Typical use and users

Used by fire testing laboratories, structural engineers, fire safety engineers, manufacturers of structural elements and protective systems, building code authorities, and researchers to evaluate and demonstrate the fire resistance of individual columns or to support design and regulatory decisions based on standardized test results. Users also rely on the standard when performing extended application analyses to apply test outcomes to real constructions.

FAQ

Q: What is this standard?

A: ISO 834‑7:2000 is an International Standard that specified the specific requirements and procedures for fire‑resistance testing of building columns.

Q: What does it cover?

A: It covers test specimen setup and orientation for columns, furnace exposure conditions (including how to handle fewer‑than‑four‑sided exposure), measurement and observation protocols, performance criteria for fire resistance, reporting requirements, and guidance on extended application analysis.

Q: Who typically uses it?

A: Fire testing laboratories, structural and fire safety engineers, manufacturers of structural elements and protective systems, building code and regulatory bodies, and researchers evaluating column fire performance.

Q: Is it current or superseded?

A: The 2000 edition has been withdrawn; it is superseded by a revised edition, ISO 834‑7:2025, published in 2025. Users should consult the 2025 edition for the current test methods and requirements.

Q: Is it part of a series?

A: Yes — ISO 834‑7 is one part of the ISO 834 series on fire‑resistance tests for elements of building construction. Other parts address general requirements and specific elements (floors, beams, walls, etc.).
