Shutters - Performance requirements including safety
This European Standard specifies the performance requirements which shutters shall fulfil when fitted to a building. It deals also with the significant hazards for construction, transport, installation, operation and maintenance of the shutters (see list of significant machine hazards in annex C).
It applies to all shutters as well as similar products whatever their use and nature of the materials used, as follows:
- external Venetian blind, roller shutter, wing shutter, Venetian shutter, flat-closing concertina shutter, concertina shutter or sliding panel shutter, with or without a system of projection.
These products can be operated manually with or without compensating spring, or by means of electric motors (power operated products).
This document is not applicable to shutters which are manufactured before the date of application of this document by CEN.
Noise aspects are not treated in the standard because this is not considered a safety issue.

EN 13659:2004+A1:2008 (E) 4 Introduction The performances given in this European Standard which illustrate suitability for use, are required for every type of shutter (intrinsic performances). Other performances are only required as a complement (specific performances) and result in specific products. Some of them are described in European Standards (e.g. EN 1522, EN 1523, ENV 1627, ENV 1628, ENV 1629, ENV 1630, EN 13123-1, EN 13124-1, EN 13123-2 and EN 13124-2). Others are described in prEN 14500 and prEN14501 in the process of preparation and deal with important subjects such as thermal comfort, i.e.: Solar factor; Shading factor; Direct solar transmittance; Secondary heat transfer factor; Solar radiation reduction factor. and visual comfort, i.e.: Light control; Night privacy; Visual contact with the outside; Glare control; Rendering of colours. or with the airborne sound insulation brought by shutters (see prEN 14759). NOTE Health and Safety regulations require that the workplace receives as much natural light as is reasonably practical (see EU Directive 89/654/EEC) and protection of operators working with VDV screens against glare control and reflected light (see EU Directive 87/391/EEC). The list of these documents is given in the Bibliography. With the aim of clarifying the intentions of the standard and avoiding doubts when reading it, following assumptions were made related to power operated products while producing it: Negotiations shall occur between the manufacturer and the purchaser concerning particular conditions for use and places for use such as for nursery schools or for buildings for disabled people which need specific risk analysis; The risk analysis carried out in this standard and the corresponding significant hazards listed in annex C suppose a normal use or normally predictable use e.g. which excludes deliberate and conscious risks taken by the user (see Interpretative Document “Safety in use” of EU Construction Products Directive).

EN 12216:2002 and the following apply. 3.1 intrinsic performance overall performances of the shutter regardless of its application as opposed to specific performance 3.2 specific performance performance which may be additional and complementary to the intrinsic performances and refers to a specific product (for example, acoustic, thermic, burglary resistance, etc.) 3.3 curtain that part of the product which is set in motion by the operating mechanism, and ensures its function 3.4 extension/retraction movement of the curtain resulting in an increase/decrease the surface area covered 3.5 opening/closing terms used to describe the increase in light (opening) or reduction of light (closing) in an extended position for products with slats or slats which can be tilted or adjusted NOTE The common parlance uses "open" for retraction and "closed" for extension. 3.6 rough operation sharp action on the operating mechanism or directly on the curtain, resulting in excessive speed at the beginning and a sudden stop at the end NOTE Rough operation is only possible if the moving part has significant inertia (mass and speed).

Wind resistance is specified through classes defined by threshold values of nominal pressure p and safety pressure γγγγ x p with γγγγ = 1,5 SIST EN 13659:2004+A1:2009
EN 13659:2004+A1:2008 (E) 8
a) Nominal wind pressure p Represents the wind pressure applied to the shutter for which the shutter shall not sustain deformation or deterioration which is detrimental to its correct operation. b) Safety wind pressure 1,5 p Represents the wind pressure applied to the shutter for which no deterioration which may be dangerous for the persons shall be observed: breakage, coming out from the fixing or locking devices. Safety wind pressure 1,5 p corresponds to a net pressure (difference of the pressures on each surface taking due account of their signs) calculated according to annex B with a wind velocity having a mean return period of 20 years (annual probability of excess of 0,05). NOTE Nominal wind pressure corresponds approximately to a wind having a mean return period of 3 years. 4.2 Determination The determination shall be in accordance with the test methods specified in EN 1932. 4.3 Performance requirement 4.3.1 General As a function of the type of shutter, the performance criteria specified in Tables 2, 3 and 4 shall be achieved having applied the test loads FN and FS as specified in Table 1.

FS = γγγγ x FN , with γγγγ = 1,5 FN = 2ββββ x p x L x H
FS = γγγγ x FN , with γγγγ = 1,5
where: L, H

EN 13659:2004+A1:2008 (E) 12 5 Resistance to snow load 5.1 General Only applicable to roller shutters for skylight and conservatory inclined less than 60° from the horizontal. Under the weight of snow, the shutter fitted to the window shall not: a) sustain deformation or deterioration which is detrimental to its correct operation; b) exit from its guide rails. Two forms of resistance are envisaged: 1) the shutter itself resists the snow pressure; 2) the shutter resists the snow pressure together with the mechanical association with the glazing, at a distance d defined by the manufacturer. This second form of resistance is allowed only if: the shutter accepts a level of deformation causing it to lean against the glazing under the snow loading; and the distance between shutter and glazing is not modified by the opening of the window. NOTE An attempt to open the window, when the shutter is loaded with snow, should not endanger the user. 5.2 Determination The determination shall be in accordance with the test method specified in EN 12833. 5.3 Performance requirement The shutter resists to the snow pressure p, maximum snow pressure specified by the manufacturer, if the following conditions are fulfilled: under nominal pressure pN, after test, the operating effort shall be maintained within the limit of the initial class; under safety load pS = fS x p with fS = 1,5, the shutter shall not exit from the guide rails or sustain breakage. 5.4 Expression of the results 1) the shutter itself resists the snow pressure: maximum snow pressure: p expressed in N/m²; form of resistance: shutter alone; shutters of the same range which are narrower and have no greater surface area than the product tested shall be deemed to be capable of resisting at least the same snow pressure as the product tested. SIST EN 13659:2004+A1:2009
EN 13659:2004+A1:2008 (E) 13
2) the shutter resists the snow pressure with the mechanical association with the glazing: maximum snow pressure: p expressed in N/m²; form of resistance: shutter in association with a glazing which withstands pressure p and located at the maximum distance d from the shutter; shutters of the same range with width and height greater than those of the product tested can be used where the distance from the glazing is the same. 5.5 Classes of snow resistance No classes are attributed for snow resistance. For each dimension, the manufacturer shall precise the maximum snow pressure the shutter can sustain, by itself or in mechanical association with a closed window. 6 Operating effort 6.1 General Does not apply for power operated products. The effort Fc necessary to set the curtain in motion in retraction / extension and tilting the laths, in addition to the projection of the curtain is a function of the type of operation. 6.2 Determination The determination shall be in accordance with the test methods specified in EN 13527. 6.3 Performance requirement and operational effort classes Operational effort FC shall not exceed the values in Table 6.

Misuse operations are related to the displacement of the curtain, the tilting of the laths and, for projected products, to the projection of the curtain. 8.1.2 Displacement of the curtain Rough operation Rough operation occurs during extension and retraction.
