ISO 834-8:2002

Fire-resistance tests - Elements of building construction - Part 8: Specific requirements for non-loadbearing vertical separating elements

ISO 834-8:2002 specifies the procedures to be followed for determining the fire resistance of non-loadbearing vertical separating elements when exposed to heating on one face. This test is neither appropriate for the evaluation of curtain walls (non-loadbearing external walls suspended from the ends of floor slabs) nor for walls containing doors or glazing. For tests of walls containing doors refer to ISO 3008. For tests of walls containing glazing refer to ISO 3009. The application of this test to other untested forms of construction is acceptable when the construction complies with the direct field of application as given in ISO 834-8:2002 or when it is subjected to a field of extended application analysis in accordance with ISO/TR 12470.

Overview - ISO 834-8:2002 (fire-resistance tests for non-loadbearing walls)

ISO 834-8:2002 defines specific procedures for determining the fire resistance of non-loadbearing vertical separating elements (walls) exposed to heating on one face. It supplements the general requirements of ISO 834-1 and is intended for test use where the wall is representative of in-service construction. The standard excludes curtain walls and walls containing doors or glazing (see ISO 3008 and ISO 3009). Application to other untested constructions is possible only within the direct field of application or after an extended application analysis per ISO/TR 12470.

Key topics and technical requirements

• Scope and exclusions: Applies only to non-loadbearing vertical separating elements; curtain walls, doors and glazed walls are handled by other standards.
• Specimen design and size: Test specimens must be fully representative or designed for wide applicability. Dimensions ≤ 3 m are tested full-size; any dimension > 3 m must be tested at no less than 3 m.
• Supporting construction & restraint: Guidance for installing smaller specimens in a furnace opening; one vertical edge may be left unrestrained with a 25–50 mm gap packed with resilient non-combustible material.
• Test frame rigidity: Increase in internal frame dimension must not exceed 5 mm under a 25 kN applied force.
• Instrumentation:
  • Furnace plate thermometers (minimum of four) distributed across the exposed face.
  • Unexposed-face thermocouples located not closer than 100 mm to any edge at specified positions.
  • Deflection measurement instrumentation to record movements greater than 5 mm at centre and near free edge.
• Performance criteria: Judged against integrity and insulation criteria defined in ISO 834-1.
• Validity & reporting: Test validity requires compliance with equipment, conditions, specimen preparation, instrumentation and procedure limits. Results and test reports follow ISO 834-1 formats.
• Safety: The standard emphasizes hazard assessment (toxic smoke, mechanical risks) and requires written safety instructions and training.

Practical applications and users

Who uses ISO 834-8:2002:

• Fire-test laboratories conducting fire-resistance tests
• Building product manufacturers (non-loadbearing partition systems)
• Fire engineers and consultants performing performance assessments and extended application analyses
• Building code authorities and certification bodies evaluating fire compartmentation solutions

Typical uses:

• Certification and performance verification of partition walls
• Providing data for fire compartmentation design and regulatory compliance
• Supporting extended field-of-application studies for similar constructions

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this part of ISO 834 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 834-8 was prepared by Technical Committee ISO/TC 92, Fire safety, Subcommittee
SC 2, Fire containment.
ISO834 consists of the following parts, under the general title Fire-resistance tests — Elements of building
construction:
— Part 1: General requirements
— Part 3: Commentary on test method and test data application
— Part 4: Specific requirements for loadbearing vertical separating elements

Introduction
This document contains specific requirements for fire resistance testing which are unique to the elements of building
construction described as vertical separating non-loadbearing elements. The requirements for these non-
loadbearing elements are intended to be applied in appropriate conjunction with the detailed and general
requirements contained in Part 1 of this International Standard (ISO 834-1).

INTERNATIONAL STANDARD ISO 834-8:2002(E)
Fire-resistance tests — Elements of building construction —
Part 8:
Specific requirements for non-loadbearing vertical separating
elements
CAUTION — The attention of all persons concerned with managing and carrying out this fire resistance test
is drawn to the fact that fire testing may be hazardous and that there is a possibility that toxic and/or harmful
smoke and gases may be evolved during the test. Mechanical and operational hazards may also arise during
the construction of the test elements or structures, their testing and disposal of test residues.
An assessment of all potential hazards and risks to health shall be made and safety precautions shall be
identified and provided. Written safety instructions shall be issued. Appropriate training shall be given to
relevant personnel. Laboratory personnel shall ensure that they follow written safety instructions at all
times.
1 Scope
This part of ISO 834 specifies the procedures to be followed for determining the fire resistance of non-loadbearing
vertical separating elements when exposed to heating on one face.
The test is neither appropriate for the evaluation of curtain walls (non-loadbearing external walls suspended from the
[2]
ends of floor slabs) nor for walls containing doors or glazing. For tests of walls containing doors refer to ISO 3008 .
[3]
For tests of walls containing glazing refer to ISO 3009 .
The application of this test to other untested forms of construction is acceptable when the construction complies with
the direct field of application as given in this document or when it is subjected to a field of extended application
[4]
analysis in accordance with ISO/TR 12470 .
NOTE Since ISO/TR 12470 gives only general guidelines, specific extended application analyses are to be performed only by
persons expert in fire resistant constructions.
