Introduction

Fire safety objectives of the project is calculated using the correlation method for predicting fires, trends and consequences, to assess fire safety measures Whether applied to effectively reduce the fire to people, buildings and the environment, provide the technical basis for achieving an acceptable level of fire safety. meter Reliability calculation method needs assessed, verified and validated.

To calculate the test method chosen has sufficient accuracy, the need to develop technical criteria for the calculation of the developer, Users and related technical personnel.

Users and need to accept the result of the calculation of any interested parties, to ensure that the calculation method can accurately enough to predict fire Development process and consequences. Therefore, the mathematical accuracy and the ability to simulate a fire phenomenon needs to be calculated reliably verified.

The accuracy of calculation of no fixed requirements, but depending on the actual needs of their application objects, does not require that all calculations are with high accuracy, but to clear the error, uncertainties and scope.

When the accuracy of this section focuses on the calculation method, but ease of use, relevance, integrity and other indicators also select the calculation method requires test Consider factors. Evaluate the adequacy calculation methods require the use of quality assurance methods, this section provides an overview of the establishment of relevant indicators of quality characteristics in principle.

Use this section for the following parties.

a) in the calculation method of development activities (including requirements analysis, design and testing, etc.) of the individual or organization;

b) is responsible for maintaining, providing computing model and evaluate model quality individuals or organizations;

Individual or organization c) application of the calculation method of analytical work;

d) Fire-makers performance design standards and specifications;

e) certification organization/official bodies responsible for assessing the application of methods and tools of assessment or certification;

f) the calculation method applied in the training of individuals or organizations.

Fire Safety Engineering Part 1. assessment of the calculation method, verification and validation

1 Scope

GB/T 31593 Part of the assessment is divided into fire safety engineering calculation methods, verification and validation process provides a framework for the implementation of which the package Include the following.

a) authentication methods that verify the correctness of equations and calculation methods given;

b) confirmation method, namely, to confirm whether the calculation method used to solve the existing problems;

c) the calculation method of the preparation of claim documents;

d) data requirements (data discrepancies predictions to be tested).

This section applies to analytical calculation methods and calculation methods complex numerical model model evaluation, verification and validation.
