11、working permitted without license from IHS -,-,- ISO/TR 14696:1999(E) ISO iv 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
12、 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 cl
13、osely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The main task of technical committees is to prepare International Standards, but in exceptional circumstances a technical committee may propose the publication of a Technical Report of
14、one of the following types: type 1, when the required support cannot be obtained for the publication of an International Standard, despite repeated efforts; type 2, when the subject is still under technical development or where for any other reason there is the future but not immediate possibility o
15、f an agreement on an International Standard; type 3, 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). Technical Reports of types 1 and 2 are subject to review within three years of
16、publication, to decide whether they can be transformed into International Standards. Technical Reports of type 3 do not necessarily have to be reviewed until the data they provide are considered to be no longer valid or useful. ISO/TR 14696, which is a Technical Report of type 2, was prepared by Tec
17、hnical Committee ISO/TC 92, Fire safety, Subcommittee SC 1, Reaction to fire. This document is being issued in the Technical Report (type 2) series of publications (according to subclause G.3.2.2 of part 1 of the ISO/IEC Directives, 1995) as a “prospective standard for provisional application” in th
18、e field of fire safety because there is an urgent need for guidance on how standards in this field should be used to meet an identified need. This document is not to be regarded as an “International Standard”. It is proposed for provisional application so that information and experience of its use i
19、n practice may be gathered. Comments on the content of this document should be sent to the ISO Central Secretariat. A review of this Technical Report (type 2) will be carried out not later than three years after its publication with the options of: extension for another three years; conversion into
20、an International Standard; or withdrawal. Annexes A to D form a normative part of this Technical Report. Annexes E and F are for information only.

22、cope This Technical Report provides a method for measuring the response of materials, products and assemblies exposed in vertical orientation to controlled levels of radiant heating with an external igniter. This test method is used to determine the ignitability, heat release rates, mass loss rates,
23、 and visible smoke development of materials, products and assemblies under well ventilated conditions. The heat release rate is determined by measurement of the oxygen consumption as determined by the oxygen concentration and flow in the exhaust product stream as specified in 11.1. Smoke development
24、 is quantified by measuring the obscuration of light by the combustion product stream. Specimens are exposed to heating fluxes ranging from 0 kW/m2 to 50 kW/m2. Hot wires are used as the ignition source. This test method has been developed for material, product or assembly evaluations, mathematical
