The work of preparing International Standards is normally carried out through ISO technical committees. Each member bo
14、dy 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 closely with the International Electrot
15、echnical Commission (IEC) on all matters of electrotechnical standardization. International 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 b
16、y the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent ri

ISO 29473 was prepared by Technical Committee ISO/TC 92, Fire safety, Subcommittee SC 1, Fire initiation and growth.

18、 Assessment of Measurement Uncertainty in Fire Tests, copyright ASTM International. BS ISO 29473:2010ISO 29473:2010(E) ISO 2010 All rights reserved vIntroduction Users of fire test data often need a quantitative indication of the quality of the data presented in a test report. This quantitative indi
19、cation is referred to as the “measurement uncertainty”. There are two primary reasons for estimating the uncertainty of fire test results: ISO/IEC 17025 requires that competent testing and calibration laboratories include uncertainty estimates for the results that are presented in a report. Fire saf
20、ety engineers need to know the quality of the input data used in an analysis to determine the uncertainty of the outcome of the analysis. General principles for evaluating and reporting measurement uncertainties are described in ISO/IEC Guide 98-3:2008. Application of ISO/IEC Guide 98-3:2008 to fire
21、 test data presents some unique challenges. This International Standard shows how these challenges can be overcome. BS ISO 29473:2010INTERNATIONAL STANDARD ISO 29473:2010(E) ISO 2010 All rights reserved 1Fire tests Uncertainty of measurements in fire tests 1 Scope This International Standard gives g
22、uidance on the evaluation and expression of uncertainty of fire test method measurements developed and maintained by ISO/TC 92, based on the approach presented in ISO/IEC Guide 98-3. Application of this International Standard is limited to tests that provide quantitative results in engineering units
23、. This includes, for example, methods for measuring the heat release rate of burning specimens based on oxygen consumption calorimetry, as in ISO 5660-1:2002. This International Standard does not apply to tests that provide results in the form of indices or binary results (e.g. pass/fail). In some c
24、ases, additional guidance will be required to supplement this International Standard. For example, the expression and use of uncertainty at low levels may require additional guidance and uncertainties associated with sampling are not explicitly addressed.
