30、Turkey and the United Kingdom. BS EN 1363-1:2012EN 1363-1:2012 (E) 6 Introduction The objective of determining fire resistance is to assess the behaviour of a specimen of an element of building construction when subjected to defined heating and pressure conditions. The method provides a means of qua

31、ntifying the ability of an element to withstand exposure to high temperatures. It does so by setting criteria against which the loadbearing capacity, the fire containment (integrity) and the thermal transmittance (insulation) functions amongst other characteristics can be evaluated. A representative

32、 sample of the element is exposed to a specified regime of heating and the performance of the test specimen is monitored on the basis of criteria described in the standard. Fire resistance of the test element is expressed as the time for which the appropriate criteria have been satisfied. The times

33、so obtained are a measure of the adequacy of the construction in a fire; but they have no direct relationship with the duration time of a real fire. Caution The attention of all persons concerned with managing and carrying out fire resistance testing is drawn to the fact that fire testing might be h

34、azardous and that there is a possibility that toxic and/or harmful smoke and gases will be emitted during the test. Mechanical and operational hazards might also arise during the construction of the test elements or structures, their testing and disposal of test residues. An assessment of all potent

35、ial hazards and risks to health needs to be made and safety precautions need to be identified and provided. Written safety instructions will be issued. Appropriate training will be given to relevant personnel. Laboratory personnel will ensure that they follow written safety instructions at all times

36、. Uncertainty of measurement of fire resistance There are many factors which can affect the result of a fire resistance test. Those concerned with the variability of the specimen including its materials, manufacture and installation are not related to the uncertainty of measurement. Of the remainder

37、, some, such as the different thermal dose provided by different furnaces, are much more significant than others such as the accuracy of calibration of the data logging system. Because of the very labour intensive nature of the test, many of the factors that have a bearing on the result are operator

38、-dependent. The training, experience and attitude of the operator is thus crucial to eliminate such variables which can significantly affect the degree of uncertainty of measurement. Unfortunately, it is not possible to numerically quantify these factors and therefore any attempt to determine uncert

39、ainty of measurement that does not take into account operator-dependent variables is of limited value. BS EN 1363-1:2012EN 1363-1:2012 (E) 7 1 Scope This European Standard establishes the general principles for determining the fire resistance of various elements of construction when subjected to sta

40、ndard fire exposure conditions. Alternative and additional procedures to meet special requirements are given in EN 1363-2. The principle that has been embodied within all European Standards relating to fire resistance testing is that where aspects and procedures of testing are common to all specific

41、 test methods e.g. the temperature/time curve, then they are specified in this test method. Where a general principle is common to many specific test methods but the details vary according to the element being tested (e.g. the measurement of unexposed face temperature), then the principle is given i

42、n this document, but the details are given in the specific test method. Where certain aspects of testing are unique to a particular specific test method (e.g. the air leakage test for fire dampers), then no details are included in this document. The test results obtained might be directly applicable

43、 to other similar elements, or variations of the element tested. The extent to which this application is permitted depends upon the field of direct application of the test result. This is restricted by the provision of rules which limit the variation from the tested specimen without further evaluati

44、on. The rules for determining the permitted variations are given in each specific test method. Variations outside those permitted by direct application are covered under extended application of test results. This results from an in-depth review of the design and performance of a particular product i

45、n test(s) by a recognised authority. Further consideration on direct and extended application is given in Annex A. The duration for which the tested element, as modified by its direct or extended field of application, satisfies specific criteria will permit subsequent classification. All values give

46、n in this Standard are nominal unless otherwise specified. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
