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

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

Standard configurations and their associated test procedures need, in due course, to
