Standard Guide for Evaluating the Predictive Capability of Deterministic Fire Models

SIGNIFICANCE AND USE
5.1 The process of model evaluation is critical to establishing both the acceptable uses and limitations of fire models. It is not possible to evaluate a model in total; instead, this guide is intended to provide a methodology for evaluating the predictive capabilities for a specific use. Validation for one application or scenario does not imply validation for different scenarios. Several alternatives are provided for performing the evaluation process including: comparison of predictions against standard fire tests, full-scale fire experiments, field experience, published literature, or previously evaluated models.  
5.2 The use of fire models currently extends beyond the fire research laboratory and into the engineering, fire service and legal communities. Sufficient evaluation of fire models is necessary to ensure that those using the models can judge the adequacy of the scientific and technical basis for the models, select models appropriate for a desired use, and understand the level of confidence which can be placed on the results predicted by the models. Adequate evaluation will help prevent the unintentional misuse of fire models.  
5.3 This guide is intended to be used in conjunction with other guides under development by Committee E05. It is intended for use by:  
5.3.1 Model Developers—To document the usefulness of a particular calculation method perhaps for specific applications. Part of model development includes identification of precision and limits of applicability, and independent testing.  
5.3.2 Model Users—To assure themselves that they are using an appropriate model for an application and that it provides adequate accuracy.  
5.3.3 Developers of Model Performance Codes—To be sure that they are incorporating valid calculation procedures into codes.  
5.3.4 Approving Officials—To ensure that the results of calculations using mathematical models stating conformance to this guide, cited in a submission, show clearly that the model is used withi...
SCOPE
1.1 This guide provides a methodology for evaluating the predictive capabilities of a fire model for a specific use. The intent is to cover the whole range of deterministic numerical models which might be used in evaluating the effects of fires in and on structures.  
1.2 The methodology is presented in terms of four areas of evaluation:  
1.2.1 Defining the model and scenarios for which the evaluation is to be conducted,  
1.2.2 Verifying the appropriateness of the theoretical basis and assumptions used in the model,  
1.2.3 Verifying the mathematical and numerical robustness of the model, and  
1.2.4 Quantifying the uncertainty and accuracy of the model results in predicting of the course of events in similar fire scenarios.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This fire standard cannot be used to provide quantitative measures.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4. Summary of Guide
4.1 A recommended process for evaluating the predictive capability of fire models is described. This process includes a brief
description of the model and the scenarios for which evaluation is sought. Then, methodologies for conducting an analysis to
quantify the sensitivity of model predictions to various uncertain factors are presented, and several alternatives for evaluating the
accuracy of the predictions of the model are provided. Historically, numerical accuracy has been concerned with time step size and
errors. A more complete evaluation must include spatial discretization. Finally, guidance is given concerning the relevant
documentation required to summarize the evaluation process.
5. Significance and Use
5.1 The process of model evaluation is critical to establishing both the acceptable uses and limitations of fire models. It is not
possible to evaluate a model in total; instead, this guide is intended to provide a methodology for evaluating the predictive
capabilities for a specific use. Validation for one application or scenario does not imply validation for different scenarios. Several
alternatives are provided for performing the evaluation process including: comparison of predictions against standard fire tests,
full-scale fire experiments, field experience, published literature, or previously evaluated models.
5.2 The use of fire models currently extends beyond the fire research laboratory and into the engineering, fire service and legal
communities. Sufficient evaluation of fire models is necessary to ensure that those using the models can judge the adequacy of the
scientific and technical basis for the models, select models appropriate for a desired use, and understand the level of confidence
which can be placed on the results predicted by the models. Adequate evaluation will help prevent the unintentional misuse of fire
models.
5.3 This guide is intended to be used in conjunction with other guides under development by Committee E05. It is intended for
use by:
5.3.1 Model Developers—To document the usefulness of a particular calculation method perhaps for specific applications. Part
of model development includes identification of precision and limits of applicability, and independent testing.
5.3.2 Model Users—To assure themselves that they are using an appropriate model for an application and that it provides
adequate accuracy.
5.3.3 Developers of Model Performance Codes—To be sure that they are incorporating valid calculation procedures into codes.
5.3.4 Approving Offıcials—To ensure that the results of calculations using mathematical models stating conformance to this
guide, cited in a submission, show clearly that the model is used within its applicable limits and has an acceptable level of accuracy.
5.3.5 Educators—To demonstrate the application and acceptability of calculation methods being taught.
5.4 This guide is not meant to describe an acceptance testing procedure.
5.5 The emphasis of this guide is numerical models of fire evolution.
5.5.1 The precision of a model refers to the deterministic capability of a model and its repeatability.
5.5.2 The accuracy of a model refers to how well the model replicates the evolution of an actual fire.
6. General Methodology
6.1 The methodology is presented in terms of four areas of evaluation:
6.1.1 Defining the model and scenarios for which the evaluation is to be conducted,
6.1.2 Assessing the appropriateness of the theoretical basis and assumptions used in the model,
6.1.3 Assessing the mathematical and numerical robustness of the model, and
6.1.4 Quantifying the uncertainty and accuracy of the model results in predicting the course of events in similar fire scenarios.
6.1.5 This general methodology is also consistent with the methodology presented in ISO 16730, Fire safety engineering –
Assessment, verification and validation of calculation methods, which is a potentially useful resource which can be used with
ASTM E1355.
6.2 Model and Scenario Documentation:
E1355 − 12 (2018)
6.2.1 Model Documentation—Sufficient documentation of calculation models, including computer software, is absolutely
necessary to assess the adequacy of the scientific and technical basis of the models, and the accuracy of computational procedures.
Also, adequate documentation will help prevent the unintentional misuse of fire models. Guidance on the documentation of
computer-based fire models is provided in Section 7.
6.2.2 Scenario Documentation—Provide a complete description of the scenarios or phenomena of interest in the evaluation to
facilitate appropriate application of the model, to aid in developing realistic inputs for the model, and to develop criteria for judging
the results of the evaluation. Details applicable to evaluation of the predictive capability of fire models are provided in 7.2.
6.3 Theoretical Basis and Assumptions in the Model—An independent review of the underlying physics and chemistry inherent
in a model ensures appropriate application of submodels which have been combined to produce the overall model. Details
applicable to evaluation of the predictive capability of fire models are provided in Section 8.
6.4 Mathematical and Numerical Robustness—The computer implementation of the model should be checked to ensure such
implementation matches the stated documentation. Details applicable to evaluation of the predictive capability of fire models are
provided in Section 9. Along with 6.3, this constitutes verification of the model.
6.5 Quantifying the Uncertainty and Accuracy of the Model:
6.5.1 Model Uncertainty—Even deterministic models rely on inputs often based on experimental measurements, empirical
correlations, or estimates made by engineering judgment. Uncertainties in the model inputs can lead to corresponding uncertainties
in the model outputs. Sensitivity analysis is used to quantify these uncertainties in the model outputs based upon known or
estimated uncertainties in model inputs. Guidance for obtaining input data for fire models is provided by Guide E1591. Details of
sensitivity analysis applicable to evaluation of the predictive capability of fire models are provided in Section 10.
6.5.2 Experimental Uncertainty—In general, the result of measurement is only the result of an approximation or estimate of the
specific quantity subject to measurement, and thus the result is complete only when accompanied by a quantitative statement of
uncertainty. Guidance for conducting full-scale compartment tests is provided by Guide E603. Guidance for determining the
uncertainty in measurements is provided in the ISO Guide to the Expression of Uncertainty in Measurement.
6.5.3 Model Evaluation—Obtaining accurate estimates of fire behavior using predictive fire models involves insuring correct
model inputs appropriate to the scenarios to be modeled, correct selection of a model appropriate to the scenarios to be modeled,
correct calculations by the model chosen, and correct interpretation of the results of the model calculation. Evaluation of a specific
scenario with different levels of knowledge of the expected results of the calculation addresses these multiple sources of potential
error. Details applicable to evaluation of the predictive capability of fire models are provided in Section 11.
7. Model and Scenario Definition
7.1 Model Documentation—Provides details of the model evaluated in sufficient detail such that the user of the evaluation could
independently repeat the evaluation. The following information should be provided:
7.1.1 Program Identification:
