Fixed firefighting systems - Watermist systems - Design and installation
This document specifies requirements and gives information on design, installation and testing and gives criteria for the acceptance of fixed landbased watermist systems for specific hazards and provides fire test protocols for a variety of hazard groups.
The requirements are not valid for watermist systems on ships, in aircraft, on vehicles and mobile fire appliances or for below ground systems in the mining industry.
The requirements can be used as a guidance for other fixed firefighting systems, however, provided that any specific requirements for other firefighting supplies are taken into account.
Aspects of watermist associated with explosion protection are beyond the scope of this document.
As the fire test scenarios of this document apply to a group of similar applications, by analogy the successful performance of watermist systems also applies to that group, as defined in Annex A. Extrapolation is not covered.
The document is not intended to be used as a universal design manual of watermist, as different systems have different characteristics and hence follow different design criteria to satisfy their duty requirements.
In the absence of a generalized design method, it is the intent of this document that watermist systems are full-scale fire tested and its system component evaluations are conducted by qualified testing laboratories.
The full system acceptance requires the relevant fire test report, the component test report(s) as well as manufacturer’s design, installation, operation and maintenance manual for the application.
If the gas in the system is a significant factor for extinguishment/suppression, the relevant parts of EN 12094 and prEN 15004-1 are applicable.
Firefighting systems in accordance with EN 12845 and water spray systems are not covered.
Ortsfeste Brandbekämpfungsanlagen - Feinsprüh-Löschanlagen - Planung und Einbau
Dieses Dokument legt Anforderungen an die Planung, Errichtung und Prüfung von Feinsprüh-Löschanlagen fest und enthält weitere Informationen dazu sowie Hinweise für Beurteilungskriterien von ortsfesten Feinsprüh-Löschanlagen für spezielle Risiken und stellt Prüfberichte für verschiedene Gruppen von Risken zur Verfügung.
Die Anforderungen gelten nicht für Feinsprüh-Löschanlagen auf Schiffen, in Flugzeugen, in Fahrzeugen und mobilen Brandsbekämpfungseinrichtungen oder für unterirdische Anlagen im Bergbau.
Die Anforderungen können für andere ortsfeste Brandbekämpfungsanlagen als Leitfaden genutzt werden, allerdings sind die spezifischen Anforderungen für andere Brandbekämpfungszwecke zu berücksichtigen.
Aspekte von Feinsprüh-Löschanlagen, die den Explosionsschutz betreffen, liegen außerhalb des Anwendungsbereichs dieses Dokuments.
Da die für dieses Dokument gewählten Szenarien für Brandprüfungen für eine Gruppe gleichartiger Anwendungen gelten, gilt analog die erfolgreich nachgewiesene Leistung von Feinsprüh-Löschanlagen ebenfalls für diese Gruppe, wie in Anhang A definiert ist. Eine Fortschreibung ist nicht behandelt.
Eine Anwendung dieses Dokuments als allgemeingültiges Handbuch für Feinsprüh-Löschanlagen ist nicht vorgesehen, da unterschiedliche Anlagen unterschiedliche Eigenschaften aufweisen und daher zur Erfüllung der Betriebsanforderungen unterschiedlichen Auslegungskriterien unterliegen.
Gibt es kein verallgemeinertes Planungsverfahren, zielt dieses Dokument darauf hin, dass Feinsprüh-Löschanlagen als unter realen Brandbedingungen geprüft zu betrachten sind und die Bewertung ihrer Anlagenbauteile durch ein qualifiziertes Prüflabor vorgenommen wird.
Die vollständige Abnahme der Anlage erfordert den entsprechenden Prüfbericht, den Bauteil-Prüfbericht sowie das Hersteller-Handbuch für Planung, Errichtung, Betrieb und Instandhaltung.
Installations fixes de lutte contre l'incendie - Systèmes à brouillard d'eau - Conception et installation
Le présent document spécifie les exigences et donne des informations relatives à la conception, à l’installation et aux essais, et donne des critères de réception des systèmes fixes à brouillard d’eau terrestres relatifs aux risques spécifiques et fournit des protocoles d’essai feu pour une variété de groupes de risques.
Les exigences ne sont pas valables pour les systèmes à brouillard d’eau sur navire, dans les avions, dans les véhicules ni aux dispositifs mobiles de lutte contre l’incendie ou pour les systèmes souterrains dans l’industrie minière.
Les exigences peuvent servir de guide à d’autres systèmes fixes de lutte contre l’incendie, à condition toutefois que toutes les exigences spécifiques relatives à d’autres dispositifs de lutte contre l’incendie soient prises en compte.
Les aspects du brouillard d’eau associés à la protection contre l’explosion ne relèvent pas du domaine d’application du présent document.
Comme les scénarios d’essai feu du présent document s‘appliquent à un groupe d’applications similaires, par analogie les performances retenues des systèmes à brouillard d’eau sont également applicables à ce groupe, tel que défini dans l‘Annexe A. L’extrapolation n’est pas prise en compte.
Le document n’est pas conçu pour être utilisé comme un manuel universel de conception des systèmes à brouillard d’eau, car des systèmes différents possèdent des caractéristiques différentes et, par conséquent, impliquent des critères de conception différents pour répondre aux exigences de leur service.
En l’absence d’une méthode de conception généralisée, le présent document vise à soumettre à essai en vraie grandeur les systèmes à brouillard d’eau et à faire évaluer leurs composants de système par des laboratoires d’essai qualifiés.

Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden,
Switzerland and the United Kingdom.
This Technical Specification (TS) was adopted by CEN for which there is the future possibility of agreement
on a European Standard, but for which at present
the required support for approval as a European Standard cannot be obtained,
there is doubt on whether consensus has been achieved,
the subject matter is still under technical development.
This Technical Specification is established with a view to serving, for instance, the purpose of
publishing aspects of a subject which may support the development and progress of the European
market,
giving guidance to the market on or by specifications and related test methods,

Introduction
The main purpose of this document is to provide information about the minimum requirements on watermist
systems.
The document devises a series of specific test conditions to set out criteria capable of verifying performance
claims of watermist systems, classify and determine the extent of their suitability for intended applications,
whilst setting a minimum level of acceptable performance and/or safety.
As individual watermist applications have varied requirements and duty, this document is intended to apply to
both skidded stand alone and pumped systems. It is the approving authority's responsibility to assess and
implement the design manual of specific watermist systems against the tests set out in this document.

This document specifies requirements and gives information on design, installation and testing and gives

The requirements are not valid for watermist systems on ships, in aircraft, on vehicles and mobile fire
appliances or for below ground systems in the mining industry.
The requirements can be used as a guidance for other fixed firefighting systems, however, provided that any
specific requirements for other firefighting supplies are taken into account.
Aspects of watermist associated with explosion protection are beyond the scope of this document.
As the fire test scenarios of this document apply to a group of similar applications, by analogy the successful
