9、tandardization) 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 ri
10、ght 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. Internationa
11、l 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
12、an International Standard requires approval by at least 75 % of the member bodies casting a vote. In other circumstances, particularly when there is an urgent market requirement for such documents, a technical committee may decide to publish other types of normative document: an ISO Publicly Availab
13、le Specification (ISO/PAS) represents an agreement between technical experts in an ISO working group and is accepted for publication if it is approved by more than 50 % of the members of the parent committee casting a vote; an ISO Technical Specification (ISO/TS) represents an agreement between the
14、members of a technical committee and is accepted for publication if it is approved by 2/3 of the members of the committee casting a vote. An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for a further three years, revised to become an International S
15、tandard, or withdrawn. If the ISO/PAS or ISO/TS is confirmed, it is reviewed again after a further three years, at which time it must either be transformed into an International Standard or be withdrawn.

ISO/TS 17431 was prepared by Technical Committee ISO/TC 92, Fire safety, Subcommittee SC 1, Fire initiation and growth. ISO/TS 17431:2006(E) ISO 2006 All rights reserved v Introduction This Technic
17、al Specification is intended to provide a test method for describing the fire behaviour of a product under fire conditions by simulating such fire conditions in a reduced scale under controlled laboratory conditions. The test method can be used as part of a fire hazard assessment that takes into acc
18、ount all of the factors that are pertinent to an assessment of a particular type of fire hazard. TECHNICAL SPECIFICATION ISO/TS 17431:2006(E) ISO 2006 All rights reserved 1 Fire tests Reduced-scale model box test WARNING So that suitable precautions can be taken to safeguard health, the attention of
19、 all concerned in fire tests is drawn to the possibility that toxic or harmful gases can be evolved during combustion of test specimens. The test procedures involve high temperatures and combustion processes from ignition to a fully developed fire. Therefore, hazards can exist for burns, ignition of
20、 extraneous objects or clothing. It is important that the operators use protective clothing, e.g. helmet, face-shield and equipment for avoiding exposure to toxic gases. Means for extinguishing a fully developed fire should be available. 1 Scope This Technical Specification specifies an intermediate
21、-scale test method that simulates a fire that under well- ventilated conditions starts in a corner of a small room with a single doorway and can develop until the room is fully involved in the fire. The method is primarily intended to evaluate the contribution to toxic hazard in, and potential for f
22、ire spread to, evacuation routes connected to the room of origin in which surface products are installed. The method is especially suitable for products with which a full-scale room test has to be terminated before the full involvement of the room with fire because of the occurrence of flashover or
23、any other safety reasons. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.
