Fire tests for building elements and components -- Fire testing of service installations

ISO 10295-1:2007 specifies the heating condition, method of test and criteria for the evaluation of the ability of a penetration sealing system to maintain the integrity and insulation of a fire separating element at the position at which it has been penetrated, for example by a service. ISO 10295-1:2007 assesses the effect of such penetrations on the integrity and insulation performance of the element concerned, the integrity and insulation performance of the penetration sealing system, the insulation performance of the penetrating service or services, and where appropriate, the integrity failure of a service. ISO 10295-1:2007 does not provide information concerning the influence of the inclusion of such penetrations and sealing systems on the load-bearing capacity of the element. It is possible that a penetration seal is a component of, or contributes to the performance of, a system to which special requirements apply. In such cases additional tests, relevant to the system and its function, can be necessary. Examples are chimneys and fire-rated ducts in air distribution systems. ISO 10295-1:2007 is not intended to provide quantitative information on the rate of leakage of smoke and/or hot gases or on the transmission or generation of fumes. Such phenomena are to be noted in describing the general behaviour of specimens during test. ISO 10295-1:2007 does not provide information on the ability of the seal to withstand stresses that can be caused by the movement or displacement of the penetration services in practice.

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.

ISO10295-1 was prepared by Technical Committee ISO/TC92, Fire safety, Subcommittee SC2, Fire

containment.

ISO10295 consists of the following parts, under the general title Fire tests for building elements and

components — Fire testing of service installations:
— Part 1: Penetration seals

A Part 2 dealing with linear joint (gap) seals and a Part 3 dealing with the methodology for establishing direct

and indirect fields of application for single component penetration seals are under preparation.

Introduction

This part of ISO 10295 has been prepared to provide a method of test for assessing the contribution of a

penetration sealing system to the fire resistance of separating elements when they have been penetrated by a

service. It should be read in conjunction with ISO 834-1. This part of ISO 10295 contains specific requirements

for fire resistance testing that are unique to the elements of building construction described as a penetration

sealing system. The requirements for these penetration sealing systems are intended to be applied as

appropriate in conjunction with the detailed and general requirements contained in ISO 834-1.

of service installations —
Part 1:
Penetration 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 can be hazardous and that there is a possibility that toxic and/or

harmful smoke and gases can be evolved during the test. Mechanical and operational hazards can 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.
1Scope

This part of ISO 10295 specifies the heating condition, method of test and criteria for the evaluation of the ability

of a penetration sealing system to maintain the integrity and insulation of a fire separating element at the

position at which it has been penetrated, for example by a service.
This part of ISO 10295 assesses

a) the effect of such penetrations on the integrity and insulation performance of the element concerned,

b) the integrity and insulation performance of the penetration sealing system,

c) the insulation performance of the penetrating service or services, and where appropriate, the integrity

failure of a service.

This part of ISO10295 does not provide information concerning the influence of the inclusion of such

penetrations and sealing systems on the load-bearing capacity of the element.

It is possible that a penetration seal is a component of, or contributes to the performance of, a system to which

special requirements apply. In such cases additional tests, relevant to the system and its function, can be

necessary. Examples are chimneys and fire-rated ducts in air distribution systems.

This part of ISO 10295 is not intended to provide quantitative information on the rate of leakage of smoke and/or

hot gases or on the transmission or generation of fumes. Such phenomena are to be noted in describing the

general behaviour of specimens during test.

This part of ISO 10295 does not provide information on the ability of the seal to withstand stresses that can be

caused by the movement or displacement of the penetration services in practice.

4 Symbols and abbreviated terms
Symbols and designations appropriate to this test are given in ISO 834-1.
5 Test equipment

5.1 Equipment employed in the conduct of this test consists of a furnace, restraint and support frames and

instrumentation as specified in ISO 834-1 and this part of ISO 10295.

5.2 The internal dimensions of the test furnace shall have a minimum size of 1m×1m×1m and shall be

such that a distance of at least 200 mm exists between any point of the periphery of any penetration seal and

the wall of the furnace.
6 Test conditions

6.1 All test conditions, except those noted herein, shall conform to those given in ISO 834-1.

6.2 Where a penetration sealing system is intended for use in both floors and walls, then each orientation shall

be tested.

6.3 A pressure of (20± 2) Pa shall be established at the bottom of the lowest penetration in a vertical

assembly.

6.4 For horizontal elements a static pressure of (20± 2) Pa in the horizontal plane (100± 10) mm below the

underside of the separating element shall exist.
7 Instrumentation

The control, monitoring and recording equipment necessary to carry out tests in accordance with this part of

ISO 10295 shall be as described in ISO 834-1.
8 Test construction
8.1 Number of specimens

8.1.1 In the case of asymmetrical vertical elements, normally two tests shall be carried out; one from each

direction of exposure. Where it can be established clearly in an asymmetrical vertical element that there is a

weaker direction of exposure, it is required to test only the weaker. A full justification for the procedure adopted

shall be included in the report. Where the penetration sealing system is fully symmetrical, only one specimen is

required to be tested with either face exposed to the heating regime.

8.1.2 In the case of horizontal elements, the test specimen shall be exposed to heating from the underside.

8.2 Size of specimen

8.2.1 A penetration and the accompanying penetration seal shall be full size. In order to avoid boundary

effects, the distance between the perimeter of the penetration sealing system and the outer perimeter of the

heated part of the separating element shall be not less than 200 mm at any point.

8.2.2 In cases where multiple penetrations are included in a single test construction, the minimum distance

between adjacent fire seals shall be not less than 200 mm. Each penetration with its associated service(s) and

penetration sealing system(s) shall be the subject of a separate evaluation providing the specified conditions

are maintained with respect to the penetration being evaluated.

8.3 Fire separating element
8.3.1 General

The fire separating elements shall be of known fire resistance and the construction details shall be

representative of that used in practice. A rating obtained on such a specific separating element shall apply only

to that particular type of separating element.
8.3.2 Standard fire separating elements
8.3.2.1 Wall constructions

The constructions depend on the period of fire resistance required. For concrete and masonry elements the wall

shall be constructed from materials having a density of (650± 200) kg/m and a thickness of not less than

70 mm.
8.3.2.2 Floor constructions

The floor constructions for concrete elements should have a density of (650± 200) kg/m or

(2 200± 250) kg/m and a thickness of not less than 100 mm.
8.4 Penetrating service
8.4.1 Selection of service(s)

8.4.1.1 The type of service or services passing through the penetration in the fire resisting element shall be

selected so as to be representative of the service which the penetration seal is designed to accommodate.

Standard service configurations for various applications are the subject of a separate document, which is in

preparation.

8.4.1.2 When more than one penetration is incorporated into a test on a single separating element whilst

remaining within the requirements of 6.3, 6.4 and 8.2, care shall be taken to ensure that there is no interaction

between different penetrations. Examples are, for instance, where the early failure at one of the penetrations

invalidates the time-temperature or pressure conditions specified or where one penetration sealing system

directly influences another, e.g. by flaming or melting.
8.4.2 Installation of service(s)

8.4.2.1 For penetration systems that are uninsulated or partially insulated, the following distances shall be

met. The exposed length of the uninsulated surface of the penetration system on the exposed face shall be a

minimum of 300 mm. The unexposed length of the uninsulated surface of the penetration system on the

unexposed face shall be a maximum of 500 mm. In this context the penetration sealing system shall include any

coating, wrapping or other protection to the services.

8.4.2.2 At the start of the test, there shall be a minimum separation of 200 mm between adjacent penetrations

and between any penetration and the internal surface of the furnace.

8.4.2.3 For the purpose of the test, the possibilities for support provided to the services are as follows:

a) unsupported condition;
b) notional support, agreed between the sponsor and the laboratory;
c) either full-scale simulation (representative of practical conditions); or

d) calculation and application of a load to simulate practical conditions. This will determine the field of direct

application.
