Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body 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 Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).

Introduction

Predicting fire behaviour is important for preventing and reducing losses due to fire. Evaluation of the performance of active fire protection systems based on the prediction of fire phenomena plays a direct part in reaching the goal of fire safety. Therefore, evaluating fire protection system performance, including system operating time and effectiveness, is important for an engineer, peer reviewer, Authority Having Jurisdiction (AHJ), fire officials and other stakeholders. It can also be useful for fire investigators to reconstruct and analyse actual fires.

The ISO 20710 series provides guidance on estimating the activation time and effectiveness of active fire protection systems when carrying out fire hazard assessments and performance-based fire safety designs for all of the abovementioned stakeholders.

This document includes information on methods for estimation, theories and data required. It also provides information on the purpose, configuration, activation procedure and functioning principles of active fire protection systems.

The methods of evaluation are hand calculation, computer fire modelling and performance testing. The objective of the ISO 20710 series is to provide guidance for performance estimation methods for analysing whether a selected system can achieve the desired performance in various environments.

1 Scope

This document provides information on the goal, scope, structure, contents and background of the different parts of the ISO 20710 series. The purpose of the ISO 20710 series is to provide information on active fire protection systems according to the design, implementation and maintenance described in ISO 23932‑1. The ISO 20710 series is linked to the steps of the performance-based fire safety engineering design process described in ISO 23932‑1.

This document is not intended as a detailed technical design guide but is intended to provide the guidance necessary for use of the ISO 20710 series by professionals who consider the active fire protection systems at each step presented in ISO 23932‑1.
