(Main)Covering - Determination of fire protection ability
Covering - Determination of fire protection ability
This document specifies a method for determining the ability of a covering to protect underlying materials against damage during a specified fire exposure.
The document is not used for the evaluation of fire resistance classifications (e.g. EI, EW, E,…) or reaction to fire classifications (according to EN 13501 1).
The fire protection ability is nullified by the presence of combustible materials in the cavity behind the covering. The applicability of the results is limited according to the quantity and position of such combustible materials within that cavity.
NOTE The amount of combustible materials permissible in the cavity is generally laid down in national regulations.
Brandschutzbekleidungen - Bestimmung der Brandschutzwirkung
Dieses Dokument legt ein Prüfverfahren zur Bestimmung der Fähigkeit einer Brandschutzbekleidung fest, die darunterliegenden Baustoffe gegen Schäden während einer definierten Brandbeanspruchung zu schützen.
Dieses Dokument wird nicht für die Bewertung der Feuerwiderstandsklassifizierungen (z. B. EI, EW, E) oder die Reaktion auf die Klassifizierung von Bränden (nach EN 13501 1) verwendet.
Die Brandschutzwirkung wird durch das Vorhandensein von brennbaren Baustoffen im Zwischenraum hinter der Brandschutzbekleidung aufgehoben. Die Anwendbarkeit der Ergebnisse ist je nach Quantität und Lage solcher brennbarer Baustoffe innerhalb dieses Zwischenraums begrenzt.
ANMERKUNG Die zulässige Menge brennbaren Baustoffs im Zwischenraum ist allgemein in nationalen Bestimmungen festgelegt.
Revêtements - Détermination de la capacité de protection contre l'incendie
Le présent document spécifie une méthode pour déterminer la capacité d’un revêtement à protéger les matériaux sous-jacents contre les dommages dans des conditions spécifiées d’exposition au feu.
Ce document n’est pas utilisé pour l’évaluation des classements de résistance au feu (par exemple EI, EW, E…) ou des classements de réaction au feu (conformément à l’EN 13501 1).
La capacité de protection contre l’incendie est annulée par la présence de matériaux combustibles dans la cavité derrière le revêtement. L’applicabilité des résultats est limitée en fonction de la quantité et de la position de ces matériaux combustibles dans la cavité.
NOTE La quantité de matériaux combustibles autorisée dans la cavité est généralement fixée par les réglementations nationales.

European foreword
This document (prEN 14135:2024) has been prepared by Technical Committee CEN/TC 127 “Fire safety
in buildings”, the secretariat of which is held by BSI.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 14135:2004.
prEN 14135:2024 includes the following significant technical changes with respect to EN 14135:2004:
— the criteria for K ;
— an additional evaluation method;
— a vertical test has been included.
This document is used in conjunction with EN 1363-1.
This document has been prepared under a standardization request addressed to CEN by the European
Commission. The Standing Committee of the EFTA States subsequently approves these requests for its
Member States.
Introduction
This document has been prepared to provide a method of test for assessing a coverings ability to protect
underlying materials against fire. This document is applicable to all coverings, including but not limited
to renderings, boards with and without air gaps and installed with various support systems.
WARNING — The attention of all persons concerned with managing and carrying out this test is drawn
to the fact that fire testing can be hazardous and that there is a possibility that toxic and/or harmful
smoke and gases are evolved during the test. Operational hazards can also arise during the testing of
specimens and the disposal of test residues.
An assessment of all potential hazards and risks to health should be made and safety precautions should
be identified and provided. Written safety instructions should be issued. Appropriate training should be
given to relevant personnel. Laboratory personnel should ensure that they follow written safety
instructions at all times.
1 Scope
This document specifies a method for determining the ability of a covering to protect underlying
materials against damage during a specified fire exposure.
The document is not used for the evaluation of fire resistance classifications (e.g. EI, EW, E,…) or reaction
to fire classifications (according to EN 13501-1).
The fire protection ability is nullified by the presence of combustible materials in the cavity behind the
covering. The applicability of the results is limited according to the quantity and position of such
combustible materials within that cavity.
NOTE The amount of combustible materials permissible in the cavity is generally laid down in national
regulations.
