10、 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.

11、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 wit

12、h 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 approv

13、al by at least 75 % of the member bodies casting a vote. In exceptional circumstances, when a technical committee has collected data of a different kind from that which is normally published as an International Standard (“state of the art”, for example), it may decide by a simple majority vote of it

17、ls iv ISO 2012 All rights reserved ISO/TR 10295-3:2012(E) Introduction This Technical Report describes a range of standard test configurations and associated testing procedures designed to determine the relevant characteristics of a penetration seal composed of one material when subjected to the sta

18、ndard fire exposure conditions outlined in ISO 834-1. It is used in conjunction with ISO 10295-1 in order to establish relationships between the parameters that influence the performance of the seal in use. The test data generated by this procedure are intended to assist in the classification of pen

19、etration seals based on their intended use and fire resistance under the specified acceptance criteria of this part of ISO 10295, i.e. their field of extended application by use of the methodology given in ISO/TR 12470. In addition, the methodology is recommended to manufacturers for use when develo

20、ping new sealing products, as it provides a way of establishing the limiting characteristics of the sealing system in a quantifiable manner. This report describes a procedure intended to be followed utilizing a well selected series of test configurations, which can be used to generate a data set to

21、characterize the fire sealing capabilities of a single component penetration seal material. The data set is intended to contain enough information to provide users with engineering data to determine the suitability of the material in applications other than that in which the material was originally

22、tested. A wide variety of product types is used to reinstate the integrity of a fire-separating element when penetrated by a service or group of services. These product types include, for example a) soft fillers (sealants or mastics); b) semi-rigid intumescent strip materials on their own or in comb

23、ination with elastomeric foam materials; c) rigid fibrous batts; d) rigid board systems; e) rigid fillers (epoxies or cementicous); f) cementicous plasters/clay/vermiculite systems. A wide variety of materials is used to “firestop” penetrations through which building services pass. These materials a

24、ll fail at some time during a fire, but the nature of the method of failure; melting, slumping, charring through etc., needs to be fully understood if a field of application is to be determined with any confidence. Standard configurations and their associated test procedures need, in due course, to

25、be derived to replicate the appropriate failure modes and also to increase the range of simulated services so the range of tests and configurations described in this part of ISO 10295 are not exhaustive. ISO 2012 All rights reserved v Fire tests for building elements and components Fire testing of s

26、ervice installations Part 3: Single component penetration seals Guidance on the construction and use of test configurations and simulated services to characterize sealing materials 1 Scope This part of ISO 10295 provides guidance in respect of a structured method of characterizing the penetrating se

27、al under test utilizing a series of defined parameters, each one being determined by the use of a selected series of test configurations in conjunction with simulated services. The level of characterization being sought is dependent upon the classification requirement of the system, which in turn de

28、termines the complexity of the test program. It is also intended the test method addresses the influence the supporting construction has on the performance of the seal system. The methods described apply to the determination of data relating to single component penetration seals where the penetratio

29、n service does not melt out within the appropriate period of exposure to a fully developed fire. The selection of the appropriate system depends upon many factors. Of particular importance is the size of the penetration, since penetration seal systems are frequently penetration size (or size range)

30、specific. This is a guidance document, its purpose being to determine the critical parameters relating to the performance of the seal being evaluated. Such parameters can then be used as a basis for interpolation and/or extrapolation of the seals performance. The procedures used have been developed

31、utilizing small square penetrations, single component penetration seals, and cylindrical conductors; however it is possible to generate a similar series of tests using rectangular cross-section conductors if this is more appropriate to end use. This part of ISO 10295 provides a structured approach d

32、esigned to establish the mode of failure; the parameters critical to the performance of the penetration seal under test. The mode of failure and critical parameters are ascertained using test configurations appropriate to the potential performance of the product, in conjunction with clearly defined

33、standard penetrations. The results gained from the application of this technical report are designed to assist a suitably qualified person to develop a direct and extended field of application for the penetration seal under test using in particular, the principles and methodology given in ISO/TR 124

34、70. Using the field(s) of application so generated, it should be possible to classify the penetration seal, thus facilitating its incorporation into specifications. The test configurations recommended in this part of ISO 10295 are not appropriate for evaluating multi- component penetration seals. Th

35、is part of ISO 10295 is not appropriate for characterizing all types of penetration seals, e.g. pipe closers/collars and some gland systems, for which evaluation using ISO 10295-1 is more appropriate. This part of ISO 10295 does not address the distance required between services that can generate th

36、eir own heat. When a live service is being evaluated, it is necessary to give consideration to the distance required between penetrations.
