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 documentsdocument 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).

Introduction
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.
This document is developed in accordance with the state of the art on the field of fire safety for railway vehicles
and the return of experiences of all committees.
In using ISO 9828 series specifies fire protection measures for railway vehicles based on the Operation
and Design Categories definedestablished in this part, the requirements laid down in the different parts of
ISO 9828 will take into account the current operating conditionsdocument.
The aim of this document is to ensure the safety of passengers and staff in the event of fire in or on a vehicle
or vehicles comprising a passenger carrying train.
Fire safety in this environment depends upon a range of interdependent measures which may include:
preventative measures; in-built precautions to mitigate the development of any incipient fire; fire detection
and alarm/warning systems; manual or automatic fire suppression systems; emergency lighting and way-
guidance systems; provisions for the availability and safe use of means of escape and egress, e.g. escape route
or exit door widths; provision of measures to assist safety interventions by the fire and rescue services; places
of safety and relative safety; occupancy levels; normal supervision; control of materials used in the
manufacture of the vehicle; ventilation; use of fire barriers and fire resistance of parts and products.
Each of these precautionary and preventative measures shall be defined in other parts of this document.
The measures and requirements specified in the ISO 9828 series are intended to protect passengers and staff
in railway vehicles in the event of a fire on board.
ISO 9828 specifies:
— — fire protection measures for railway vehicles.
The protection of passengers and staff is essentially based on measures to:
— — prevent fires occurring due to technical faults and due to equipment design or vehicle layout;,
— — minimiseminimize the possibility of ignition of materials installed on railway vehicles due to accidents
or vandalism (acts of damaging public property);),
— — detect the occurrence of a fire should it occur;,
— — limit the spread of fire by specification of materials according to the operational categories (and by
measures for containment);
— — minimiseminimize the effects of fire in terms of heat, smoke and toxic gases on passengers or staff
through the specification of materials installed on railway vehicles;
— — control and manage a fire, for example, by means of fire detection, suppression and/or emergency
energy shut down.
The ultimate objective in the event of a fire on boardaim of this document is to allow ensure the safety of
passengers and staff to evacuatein the railwayevent of a fire in or on a vehicle or vehicles comprising a
passenger carrying train. In this environment, fire safety depends upon a range of interdependent measures,
such as:

— preventive measures;
— in-built precautions to mitigate the development of any incipient fire;
— fire detection and reach a place of safety.alarm/warning systems;
— The presentmanual or automatic fire suppression systems;
— emergency lighting and way-guidance systems;
— provisions for the availability and safe use of means of escape and egress (e.g. escape route or exit door
widths);
— measures to assist safety interventions by the fire and rescue services;
— places of safety and relative safety;
— occupancy levels;
— normal supervision;
— control of materials used in the manufacture of the vehicle;
— ventilation;
— use of fire barriers;
— fire resistance of parts and products.
Each of these precautionary and preventive measures are defined in other parts of the ISO 9828 series.
This document describes the measures to be taken in the design of the vehicles in the context of each country’s
infrastructure.
The International Organization for Standardization (ISO) draws attention to the fact that it is claimed that
compliance with this document may involve the use of a patent.
ISO takes no position concerning the evidence, validity and scope of this patent right.
The holder of this patent right has assured ISO that he/she is willing to negotiate licences under reasonable
and non-discriminatory terms and conditions with applicants throughout the world. In this respect, the
statement of the holder of this patent right is registered with ISO. Information may be obtained from the patent
database available at .
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights other than those in the patent database. ISO shall not be held responsible for identifying any or all such
patent rights.
