21、lidation of calculation methods Part 1: General.iv ISO 2015 All rights reservedBS ISO 16730-1:2015ISO 16730-1:2015(E)IntroductionThe objective of fire safety engineering is to assist in the achievement of an acceptable predicted level of fire safety. Part of this work involves the use of calculation

22、 methods to predict the course of events potentially occurring in case of a fire or as a consequence of a fire, and evaluate the ability of fire protection measures to mitigate the adverse effects of a fire on people, property, the environment and other objectives.The main principles necessary for e

23、stablishing credibility of these calculation methods are verification and validation. This International Standard addresses the procedures for verification and validation of calculation methods for fire safety engineering in general.Potential users of calculation methods and those who are asked to a

24、ccept the results need to be assured that the calculation methods provide sufficiently accurate predictions of the course and consequences of the fire for the specific application planned. To provide this assurance, the calculation methods chosen need to be verified for mathematical accuracy and val

25、idated for capability to reproduce the phenomena. A rigorous verification and validation process is a key element of quality assurance.There is no fixed requirement of accuracy that is applicable to all calculation methods. The accuracy level depends on the purposes for which a calculation method is

26、 to be used. Not all calculation methods need to demonstrate high accuracy as long as the error, uncertainty and limits of applicability of the calculation methods are known.This International Standard focuses on the predictive accuracy of calculation methods. However, other factors such as ease of

27、use, relevance, completeness and status of development play an important role in assessing the most appropriate method to use for a particular application. The assessment of the suitability of a calculation method for a special purpose within the field of fire safety engineering is supported by the

28、use of quality assurance methodology for the proof of the requirements being fulfilled. Guidance for establishing metrics for measuring the attributes of the relevant quality characteristics is outlined in brief in this International Standard.This International Standard contains elements that are in

29、tended, in part or in whole, to be used bya) developers of calculation methods (individuals or organizations who perform development activities, including requirement analysis, design and testing of components) to document the usefulness of a particular calculation method, perhaps for specific appli

30、cations. Part of the calculation method development includes identification of precision and limits of applicability, and independent testing,b) developers of calculation methods (individuals or organizations who maintain computer models, supply computer models and for those who evaluate computer mo

31、del quality as part of quality assurance and quality control) to document the software development process to assure users that appropriate development techniques are followed to ensure quality of the application tools,c) users of calculation methods (individuals or organizations who use calculation

32、 methods to perform an analysis) - to assure themselves that they are using an appropriate method for a particular application and that it provides adequate accuracy,d) developers of performance codes and standards - to determine whether a calculation method is appropriate for a given application,e)

33、 approving bodies/officials (individuals or organizations who review or approve the use of assessment methods and tools) - to ensure that the calculation methods submitted show clearly that the calculation method is used within its applicability limits and has an acceptable level of accuracy, andf)

34、educators - to demonstrate the application and acceptability of calculation methods being taught. ISO 2015 All rights reserved vBS ISO 16730-1:2015ISO 16730-1:2015(E)Users of this International Standard should be appropriately qualified and competent in the fields of fire safety engineering and risk

35、 assessment. It is important that users understand the parameters within which specific methodologies may be used.General principles are described in ISO 23932, which provides a performance-based methodology for engineers to assess the level of fire safety for new or existing built environments. Fir

36、e safety is evaluated through an engineered approach based on the quantification of the behaviour of fire and based on knowledge of the consequences of such behaviour on life safety, property and the environment. ISO 23932 provides the process (necessary steps) and essential elements to design a rob

37、ust performance-based fire safety programme.ISO 23932 is supported by a set of fire safety engineering International Standards available on the methods and data needed for the steps in a fire safety engineering design summarized in ISO 23932:2009, Clause 4 and shown in Figure 1 (taken from ISO 23932

38、:2009, Clause 4). This set of International Standards is referred to as the Global fire safety engineering analysis and information system. This global approach and system of standards provides an awareness of the interrelationships between fire evaluations when using the set of fire safety engineer

39、ing International Standards. The set includes ISO 16733-11), ISO 16732-1, ISO 16734, ISO 16735, ISO 16736, ISO 16737, ISO/TS 24679, ISO 16730-1, ISO 297612), ISO/TS 13447, and other supporting technical reports that provide examples of and guidance on the application of these standards.Each Internat

40、ional Standard supporting the global fire safety engineering analysis and information system includes language in the introduction to tie the standard to the steps in the fire safety engineering design process outlined in ISO 23932. ISO 23932 requires that calculation methods used in scenario-based

41、evaluations of trial designs (ISO 23932:2009, Clause 11) be verified and validated. Pursuant to the requirements of ISO 23932, this International Standard provides the procedures and requirements for the verification and validation of fire calculation methods.
