Fire-resistance tests -- Elements of building construction

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.

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
— Part 5: Specific requirements for loadbearing horizontal separating elements
— Part 6: Specific requirements for beams
— Part 7: Specific requirements for columns
— Part 8: Specific requirements for non-loadbearing vertical separating elements
— Part 9: Specific requirements for non-loadbearing ceiling 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).

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.
2 Normative references

this part of ISO 834. For dated references, subsequent amendments to, or revisions of, any of these publications do

not apply. However, parties to agreements based on this part of ISO 834 are encouraged to investigate the possibility

of applying the most recent editions of the normative documents indicated below. For undated references, the latest

edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid

International Standards.

For the purposes of this part of ISO 834, the terms and definitions given in ISO 834-1, ISO 13943 and the following

apply.
3.1
vertical separating elements

vertically oriented building elements, such as walls, which are required to act as fire separations or fire barriers,

divide buildings into fire compartments or fire zones, or separate a building from adjoining buildings, in order to resist

the spread of fire to or from adjoining compartments or buildings
3.2
non-loadbearing wall

separating element designed not to be subject to any load other than its own mass

3.3
insulated non-loadbearing wall
separating element, which satisfies both the integri
