External blinds and awnings - Performance requirements including safety

This European Standard specifies the performance requirements for blinds and awnings intended to be fitted externally to buildings and other construction works. It deals also with the significant hazards for assembly, transport, installation, operation and maintenance (see list of significant machine hazards in Annex B).
It applies to all external blinds and awnings whatever their design and nature of the materials used, as follows and defined in EN 12216:
―   folding arm awning, trellis arm awning, pivot arm awning, slide arm awning, vertical roller blind, marquisolette, façade awning, skylight awning, conservatory awning, Pergola awning, Dutch awning, insect screen; brise-soleil.
This European Standard does not cover the wind resistance of non-retractable products, e.g. Dutch awnings and brise-soleil.
The structural part to which the Pergola awning is fixed is not covered.
The products covered by this European Standard may be operated manually, with or without compensating springs or by means of electric motors (power operated products). However, the durability and endurance of the autonomous supply for power operated external blinds and awnings not connected to the mains supply are not covered.
This European Standard deals also with all significant hazards, hazardous situations and events when external blinds and awnings are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Annex B).
This European Standard covers external blinds and awnings mounted externally. In case such products are installed internally, they should fulfil all relevant safety requirements defined in EN 13120.
The noise emission of power operated external blinds and awnings is not considered to be a relevant hazard according to the machinery health and safety requirements. Therefore this European Standard does not contain any specific requirements on noise health and safety objective.

Markisen - Leistungs- und Sicherheitsanforderungen

Diese Europäische Norm legt die Leistungsanforderungen für Markisen fest, die zur äußeren Befestigung an Gebäuden und anderen baulichen Anlagen vorgesehen sind. Sie behandelt auch wesentliche Gefährdungen bei Zusammenbau, Transport, Einbau, Bedienung und Wartung (siehe Liste der signifikanten Gefährdungen in Anhang B).
Sie gilt für alle Markisen, unabhängig von deren Gestaltung und der Art der verwendeten Werkstoffe, wie im Folgenden und in EN 12216 festgelegt:
-   Gelenkarmmarkise, Scherenarmmarkise, Fallarmmarkise, Fallarmmarkise geführt, Senkrechtmarkise, Markisolette, Fassadenmarkise, Dachflächenfenstermarkise, Wintergartenmarkise, Pergolamarkise; Korbmarkise, Insektenschutzgitter, Sonnenblende.
Diese Europäische Norm behandelt nicht den Windwiderstand von nicht einfahrbaren Produkten, wie z. B. Korb-markisen und Sonnenblenden.
Das Bauteil, an dem die Pergolamarkise befestigt ist, wird nicht behandelt.
Die Produkte, die in dieser Europäischen Norm behandelt werden, können manuell, mit oder ohne Ausgleichsfedern oder mit Elektromotoren (kraftbetätigte Produkte) bedient werden. Dennoch werden Haltbarkeit und Lebensdauer der eigenständigen Stromversorgung kraftbetätigter Markisen, die nicht mit der Hauptstromversorgung verbunden sind, nicht behandelt.
Diese Europäische Norm behandelt zugleich wesentliche Gefährdungen, Gefährdungssituationen und Gefährdungsereignisse, die bei bestimmungsgemäßer Verwendung der Markisen sowie unter den Bedingungen eines unsachgemäßen Gebrauchs auftreten können, die durch den Hersteller sinnvollerweise vorhersehbar sind (siehe Anhang B).
Diese Europäische Norm behandelt Markisen, die im Außenbereich montiert sind. In Fällen, in denen diese Produkte an der Innenseite montiert sind, sollten sie sämtliche in EN 13120 festgelegten Sicherheits-anforderungen erfüllen.
Die Geräuschemission von kraftbetätigten Markisen wird nach den Sicherheits- und Gesundheits¬anforderungen für Maschinen nicht als maßgebliche Gefährdung angesehen. Aus diesem Grund enthält diese Europäische Norm keine spezifischen Anforderungen an sicherheits- und gesundheitsbezogene Geräuschziele.

Stores extérieurs - Exigences de performance, y compris la sécurité

La présente Norme Européenne spécifie les exigences de performance relatives aux stores destinés à être fixés à l'extérieur des bâtiments et autres ouvrages de construction. Elle traite également des phénomènes dangereux significatifs liés à l'assemblage, au transport, à l'installation, au fonctionnement et à l'entretien (voir la liste des phénomènes dangereux significatifs à l’Annexe B).
Elle s'applique à tous les stores extérieurs, quelles que soient leur conception et la nature des matériaux utilisés, tels que définis dans l'EN 12216 et listés ci-après :

La présente Norme Européenne ne traite pas de la résistance au vent des produits non repliables, par exemple les stores corbeilles ou les brise-soleil.
Les éléments de structure auxquels le store de pergola est fixé ne relèvent pas du domaine d'application de la présente Norme Européenne.
Les produits couverts par la présente Norme Européenne peuvent être manœuvrés manuellement, avec ou sans ressorts de compensation ou au moyen de moteurs électriques (produits motorisés). Cependant, la durabilité et l'endurance du système d'alimentation autonome des stores extérieurs motorisés qui ne sont pas reliés à l'alimentation principale ne relèvent pas du domaine d'application de la présente Norme Européenne.
La présente Norme Européenne traite de tous les phénomènes dangereux, situations et événements dangereux significatifs, lorsque les stores extérieurs sont utilisés selon l'usage prévu et dans des conditions de mauvais usage raisonnablement prévisible par le fabricant (voir Annexe B).
La présente Norme Européenne s'applique aux stores montés en extérieur. Dans le cas où des produits de ce type sont installés en intérieur, il convient qu'ils répondent aux exigences de sécurité correspondantes de l'EN 13120.
Les émissions sonores des stores extérieurs motorisés ne sont pas considérées comme un phénomène dangereux pertinent selon les exigences de santé et de sécurité des machines. Par conséquent, la présente Norme Européenne ne comporte aucune exigence spécifique de santé et de sécurité en matière de bruit.

EN 13561:2015 (E) 6 Introduction This document is a type C standard as stated in EN ISO 12100. The machinery concerned, i.e. power operated products, and the extent to which hazards, hazardous situations and hazardous events are covered are indicated in the scope of this document. When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard. SIST EN 13561:2015

EN 13561:2015 (E) 7 1 Scope This European Standard specifies the performance requirements for blinds and awnings intended to be fitted externally to buildings and other construction works. It deals also with the significant hazards for assembly, transport, installation, operation and maintenance (see list of significant machine hazards in Annex B). It applies to all external blinds and awnings whatever their design and nature of the materials used, as follows and defined in EN 12216:

folding arm awning, trellis arm awning, pivot arm awning, slide arm awning, vertical roller blind, marquisolette, façade awning, skylight awning, conservatory awning, Pergola awning, Dutch awning, insect screen; brise-soleil. This European Standard does not cover the wind resistance of non-retractable products, e.g. Dutch awnings and brise-soleil. The structural part to which the Pergola awning is fixed is not covered. The products covered by this European Standard may be operated manually, with or without compensating springs or by means of electric motors (power operated products). However, the durability and endurance of the autonomous supply for power operated external blinds and awnings not connected to the mains supply are not covered. This European Standard deals also with all significant hazards, hazardous situations and events when external blinds and awnings are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Annex B). This European Standard covers external blinds and awnings mounted externally. In case such products are installed internally, they should fulfil all relevant safety requirements defined in EN 13120. The noise emission of power operated external blinds and awnings is not considered to be a relevant hazard according to the machinery health and safety requirements. Therefore this European Standard does not contain any specific requirements on noise health and safety objective. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

EN 13561:2015 (E) 10 3.14 determination of performance means of verification of the performance relating to the corresponding requirement 4 Product characteristics 4.1 Resistance to wind loads The wind resistance of an external blind is characterized by its ability to withstand specified loads simulating the action of wind in positive or negative pressure. Wind resistance is specified through classes defined by threshold values of nominal pressure pN and safety pressure pS =

x pN with
= 1,2:

Nominal wind pressure pN: it represents the wind pressure under which the external blind shall not sustain deformation or deterioration detrimental to its correct operation.

Safety wind pressure pS: it represents the wind pressure under which no deterioration which may be dangerous for the persons shall be observed (e.g. breakage, exit from guiding tracks in case of guided blinds). When tested according to EN 1932, the wind resistance class of external blinds shall be given according to Table 1. Table 1 — Classes of wind resistance Classes 0 1 2 3 4 5 6 Nominal wind pressure pN (N/m2) < 40 40 70 110 170 270 400 Safety wind pressure pS (N/m2) < 48 48 84 132 204 234 480 Table 1 applies to all external blinds. However, the maximum class allowed for folding arm awnings shall be class 2. Classes from 4 to 6 are only allowed for external blinds with fabric running in lateral guide rails and Pergola awnings. NOTE 1 This maximum class for folding arm awnings has been defined to take into account the resistance of the fixing system and the dynamic effect of the wind. The manufacturer shall define a maximum speed above which the external blind shall be retracted. This wind speed shall be indicated in the instructions for use. For folding arm awnings and trellis arm awnings having more than two arms, the size limit for the same class shall be determined considering the maximum width of fabric applied to one arm for the same projection (H). NOTE 2 The conditions to be met in order to fulfil the performance requirement are based on static loads and do not consider the dynamic effect of repeated loads (turbulences) to which the fabric and the frame are submitted in an actual situation. Therefore, the static pressure cannot be used to define the anchoring of the external blinds on the building. 4.2 Resistance of non retractable elements to pressure loads Since some parts of external blinds – for example head boxes, guiderails – cannot be retracted, they shall withstand in some cases very high wind speed. The resulting pressure on the product depends on:

the installation condition, SIST EN 13561:2015
EN 13561:2015 (E) 11
the height of the building,

the location of the building. This clause applies to the external blind itself. It does not cover the fixing of the external blind to its support for which the manufacturer shall give guidance in the instructions for installation (see 6.3.2). NOTE 1 As the criteria determining the resulting pressure applied to the fixed parts of external blinds are depending on installation conditions (location, height,…). National rules – if available – can give such information on the basis of National wind speed map. When calculated accord
