ISO/DIS 10295-2
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 2.

The main task of technical committees is to prepare International Standards. 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 document may be the subject of patent

rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 10295-2 was prepared by Technical Committee ISO/TC 92, Fire safety, Subcommittee SC 2, Fire

containment.

ISO 10295 consists of the following parts, under the general title Fire tests for building elements and

components — Integrity and insulation performance testing of service installations:

 Part 1: Penetration seals
 Part 2: Linear gap seals

NOTE There is a document being developed titled: Part 3: Penetration seals. Guidance on the use of test

configurations to establish direct and extended fields of application, with two subsections: Single component penetration

seals and Multi-component penetration seals.

ISO/DIS 10295-2
Introduction

This International Standard describes test methods used to determine the fire resistive nature of joint seals

when subjected to the standard fire exposure conditions outlined in ISO 834: Part 1. The test data generated

by this standard will permit the classification of these various joint seals based on their intended use and fire

endurance under the specified acceptance criteria of this standard.

Joint seals are positioned in joints, voids, gaps, or other discontinuities between or bounded by two or more

supporting elements. Normally such openings are denoted as ‘linear’ because the length is greater than their

width defined by a typical ratio of at least 10:1 as in practice. Joints are present in buildings as a result of:

i) design to accommodate various movements induced by thermal differentials, seismicity, and

wind loads and exist as a clearance separation;

ii) acceptable dimensional tolerances between two or more building elements, eg between non-

loadbearing walls and floors;
iii) inadequate design, inaccurate assembly, repairs or damage to the building.

This standard describes methods of test for evaluating joint seals based on their intended use. The standard

also allows for the application of movement prior to and/or during fire testing.

This standard provides the requirements for the test specimen, the test construction, the equipment (including

any special apparatus or instrumentation), the procedures and acceptance criteria as they apply to joint seals

and their supporting elements.

DRAFT INTERNATIONAL STANDARD ISO/DIS 10295-2
Fire tests for building elements and components — Integrity
and insulation performance testing of service installations —
Part 2: Linear joint (gap) seals

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 standard specifies the heating conditions, methods of test and criteria for the evaluation of the ability of a

linear joint seals to maintain the integrity and insulation of a fire separating element at the joint to be sealed.

Test results shall register material performance during the fire exposure period and shall not be construed as

having determined material suitability for use after that exposure. The purpose of the tests is to assess the

integrity and insulation performance of the linear joint seals, including the effects of induced movement in

those cases where the joint is designed to accommodate movement and has a width of > 20 mm.

It is not the intention through this test to provide quantitative information on the rate of leakage of smoke

and/or gases, or on the transmission or generation of fumes. Such phenomena shall be noted in describing

the general behaviour of specimens during test. It is not the intention of this test procedure to evaluate joint

seals where special test procedures already exist, e.g. doors, partitions, penetrations, pipes, ducts and cables.
