18、generated and the production of smoke and gaseous products of combustion. Consequently, early codes and regulations for fire safety were designed to prevent rapid fire development and spread within individual structures and also from one structure to another. These codes have since developed into mo

19、re complex laws governing public safety. Formerly, a distinction was made between the protection of persons from fire and the protection of property, with more importance being placed upon the latter. However, this distinction becomes somewhat difficult to make when considering modern, large-area, h

20、igh-rise structures, where protection of the occupants in-place needs to be substituted for rapid evacuation. Restrictions on the use of combustible materials, compartmentalization, early fire detection, and suppression are key factors for in-place protection of occupants and are also important for

21、minimizing property loss. Real-scale fire tests are the ideal way to quantify the fire hazard of products. However, such tests are impractical in the vast majority of cases. The reaction-to-fire tests developed by ISO/TC 92/SC 1 seek to quantify aspects of the fire hazard that may result from the us

22、e of particular products in particular applications in a meaningful, cost-effective, and reproducible way. This Technical Specification describes the work being carried out by ISO/TC 92/SC 1 on the development of tests and guidance for the “reaction-to-fire” of products and discusses the role and li

23、mitation of these tests in reducing fire danger. ISO 2014 All rights reserved vPD ISO/TS 3814:2014PD ISO/TS 3814:2014Standard tests for measuring reaction-to-fire of products and materials Their development and application 1 Scope This Technical Specification describes the relevance of, and how to a

24、pply, the fire tests developed by ISO/TC 92/SC 1 so that they can be used effectively to reduce the hazard of fire. Each reaction-to-fire test is related to the different phases of a developing fire in buildings and transport and has to be seen in its relation to the fire scenario and phase of the f

25、ire it represents. Some reaction-to-fire tests are proposed to assess the fire hazard in those different phases. Although this Technical Specification does not address smouldering combustion, this does not mean that smouldering is not important in some fire development situations. However, there are

26、 no tests in Subcommittee 1 (SC 1) which currently address this phenomenon. This Technical Specification is aimed at indicating those ISO tests which produce relevant and useful data for fire safety engineering and those which do not. This Technical Specification is also of use to regulators, people

27、 who are performing reaction-to-fire tests including manufacturers and all people who are responsible to create, control, and assess fire safety concepts. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its ap

41、TE ISO 13943 defines reaction-to-fire as the response of a product (material) in contributing by its own decomposition to a fire to which it is exposed, under specified conditions. 4 Development of reaction to fire tests Authorities responsible for fire safety in many countries have been concerned o

42、ver the years about the safe use of materials in the construction environment. A number of national test methods have, therefore, been developed to provide the data necessary to identify the important characteristics of 2 ISO 2014 All rights reservedPD ISO/TS 3814:2014ISO/TS 3814:2014(E) materials a

43、nd products under fire conditions. These tests, most of which are of laboratory scale, are collectively referred to as “reaction-to-fire” tests and include ignitability, surface spread of flame, smoke development and obscuration, rate of heat release, non-combustibility, and corner, wall, and/or roo

44、m fire development. The original “reaction-to-fire” tests were generally developed with particular hazards, or fire situations, in mind. For example, the predecessors of the modern surface spread of flame tests were developed in the 1930s and 1940s using flame or radiative heat exposure to represent

45、 a fire burning freely in one corner of a room. Such tests are frequently referred to as “open tests”. Later developments led to tests which included a representation of the room itself, these tests being called “enclosure tests” or “box tests”. In the latter case some, or all of the heat produced b

46、y the burning material, is retained in the enclosure and therefore can in turn affect more of the material. Consequently, fire exposures in “enclosure tests” are often more severe (in terms of heat release rate) than in “open tests”. Some tests are designed to measure more than one fire parameter. T

47、he individual results can sometimes be used independently, although the importance attached to each can vary, whereas in others the test results can be combined empirically to produce an index, or a range of indices, of performance. Considerable care should be taken when interpreting the results of

48、such combined tests. Because the various national reaction-to-fire test methods have been developed in different ways, even though they are intended to measure essentially the same fire characteristics, it has proved very difficult, and in some cases impossible, to obtain any meaningful correlations

49、 between the test results obtained when using them. This has created major difficulties, both for the product manufacturers and for regulatory authorities around the world, when comparing the fire performance of products which have been tested using different national test methods. Additional problems have also arisen concerning international acceptance of fire test data, and in some cases these have created barriers to trade. In attempt to re
