The work of preparing International Standards is normally carried out t

8、hrough ISOtechnical committees. Each member body interested in a subject for which a technical committee has beenestablished has the right to be represented on that committee. International organizations, governmental andnon-governmental, in liaison with ISO, also take part in the work. ISO collabor

9、ates closely with the InternationalElectrotechnical 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

10、 Draft International Standardsadopted by the technical committees are circulated to the member bodies for voting. Publication as anInternational 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 do

ISO shall not be held responsible for identifying any or all such patent rights.ISO 10295-1 was prepared by Technical Committee ISO/TC 92, Fire safety, Subcommittee SC 2, Firecontainment.ISO 10295 consists of the following parts, under the general title Fir

13、der preparation.BS ISO 10295-1:2007vIntroductionThis part of ISO 10295 has been prepared to provide a method of test for assessing the contribution of apenetration sealing system to the fire resistance of separating elements when they have been penetrated by aservice. It should be read in conjunctio

14、n with ISO 834-1. This part of ISO 10295 contains specific requirementsfor fire resistance testing that are unique to the elements of building construction described as a penetrationsealing system. The requirements for these penetration sealing systems are intended to be applied asappropriate in con

15、junction with the detailed and general requirements contained in ISO 834-1.BS ISO 10295-1:2007blank1Fire tests for building elements and components Fire testing of service installations Part 1:Penetration sealsCAUTION The attention of all persons concerned with managing and carrying out this fire re

16、sistancetest is drawn to the fact that fire testing can be hazardous and that there is a possibility that toxic and/orharmful smoke and gases can be evolved during the test. Mechanical and operational hazards can alsoarise during the construction of the test elements or structures, their testing and

17、 disposal of testresidues.An assessment of all potential hazards and risks to health shall be made and safety precautions shallbe identified and provided. Written safety instructions shall be issued. Appropriate training shall begiven to relevant personnel. Laboratory personnel shall ensure that the

18、y follow written safetyinstructions at all times.1ScopeThis part of ISO 10295 specifies the heating condition, method of test and criteria for the evaluation of the abilityof a penetration sealing system to maintain the integrity and insulation of a fire separating element at theposition at which it

19、 has been penetrated, for example by a service.This part of ISO 10295 assessesa) 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 pen

20、etrating service or services, and where appropriate, the integrityfailure of a service.This part of ISO 10295 does not provide information concerning the influence of the inclusion of suchpenetrations and sealing systems on the load-bearing capacity of the element.It is possible that a penetration s

21、eal is a component of, or contributes to the performance of, a system to whichspecial requirements apply. In such cases additional tests, relevant to the system and its function, can benecessary. Examples are chimneys and fire-rated ducts in air distribution systems.This part of ISO 10295 is not int

22、ended to provide quantitative information on the rate of leakage of smoke and/orhot gases or on the transmission or generation of fumes. Such phenomena are to be noted in describing thegeneral behaviour of specimens during test.This part of ISO 10295 does not provide information on the ability of th

23、e seal to withstand stresses that can becaused by the movement or displacement of the penetration services in practice.NOTE Explanatory notes are included in Annex A.BS ISO 10295-1:200722 Normative referencesThe following referenced documents are indispensable for the application of this document.

Where it can be established clearly in an a

35、symmetrical vertical element that there is aweaker direction of exposure, it is required to test only the weaker. A full justification for the procedure adoptedshall be included in the report. Where the penetration sealing system is fully symmetrical, only one specimen isrequired to be tested with e

In order to avoid boundaryeffects, the distance betwee

43、stremaining within the requirements of 6.3, 6.4 and 8.2, care shall be taken to ensure that there is no interactionbetween different penetrations.
