External blinds and awnings - Performance requirements including safety

This European Standard specifies the performance requirements which external blinds shall fulfil when fitted to a building. It deals also with the significant hazards for construction, transport, installation, operation and maintenance of the external blinds (see list of significant machine hazards in annex B). It applies to all external blinds as well as similar products 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 awning, marquisolette, façade awning, skylight awning, conservatory awning, Dutch awning, insect screen; - solar screen. This European Standard does not cover the wind resistance of fixed nor semi-fixed products, e.g. Dutch awnings, fixed or mobile and solar screen. They are not exempt from wind resistance requirements although no test methods have been established at the present time. 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). This document is not applicable to external blinds which are manufactured before the date of publication of this document.

Introduction
The performances given in this European Standard which illustrate suitability for use, are required for every
type of external blind and awnings (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). Others are
described in EN 14500 and EN 14501 which are related to important issues such as thermal comfort, i.e.:
 Solar factor;
 Shading factor;
 Direct solar transmittance;
 Secondary heat transfert factor;
and visual comfort, i.e.:
 Light control;
 Night privacy;
 Visual contact with the outside;
 Glare control;
 Use of daylight;
 Rendering of colours.
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 European Standard and the corresponding significant hazards listed
in Annex Bsuppose 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).

1 Scope
This European Standard specifies the performance requirements which external blinds and awnings shall
fulfil when fitted to a building. It deals also with the significant hazards for construction, transport, installation,
operation and maintenance (see list of significant machine hazards in Annex B).
It applies to all external blinds and awnings as well as similar products 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 awning,
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 fixed nor semi-fixed products, e.g. Dutch
awnings, fixed or mobile and brise-soleil. These types of products shall be evaluated according to the
relevant calculation methods (such as Eurocodes).
This European Standard covers the wind resistance of the retractable part of Pergola awnings. However, the
structural part of these products is not covered and shall be evaluated according to the relevant calculation
methods (such as Eurocodes).
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).
NOTE This 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.
This document is not applicable to external blinds and awnings which are manufactured before the date of
publication of this document.
The noise emission of power operated external blinds and awnings is not considered to be a relevant hazard.
Therefore this standard does not contain any specific requirements on noise in relation to the Machinery
Directive.
If not specified otherwise, the term "external blind" used in this document refers to any type of external blinds
or awnings included in the scope of this European Standard.

4 Wind resistance
4.1 In the extended position
4.1.1 General
The wind resistance of an external blind is characterised 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 p and safety
N
pressure p = γ x p with γ = 1,2:
S N
 Nominal wind pressure p : it represents the wind pressure under which the external blind shall not
N
sustain deformation or deterioration detrimental to its correct operation.
 Safety wind pressure p : it represents the wind pressure under which no deterioration which may be
S
dangerous for the persons shall be observed (e.g. breakage, exit from guiding tracks in case of guided
blinds).
4.1.2 Determination
The determination shall be in accordance with the test methods specified in FprEN 1932:2011.
NOTE The FprEN 1932:2011 specifies that the test samples shall be of the following dimensions: the maximum
width associated with the greatest height achievable with this width and the maximum height associated with the greatest
width achievable with this height. Therefore, two tests are necessary for a same range of external blinds.
4.1.3 Performance requirement
4.1.3.1 General
Depending on the type of external blind considered, the performance criteria applicable and specified in:
 clause 7.1.6 of prEN 1932:2011 for folding arm and treillis arm awnings,
 clause 7.2.6 of prEN 1932:2011 for projecting awning and marquisolette,
 clause 7.3.6 of prEN 1932:2011 for awnings with lateral guiderail without tension system,
 clause 7.4.6 of prEN 1932:2011 for awnings with lateral guiderail with fabric running into the lateral
rails without tension system,
8

---------------------- Page: 10 ----------------------
oSIST prEN 13561 rev:2011
prEN 13561:2011 (E)
 clause 7.5.6 of prEN 1932:2011 for awning with lateral guiderail with tension system
or
 clause 7.6.6 of prEN 1932:2011 for the retractable part of Pergola awnings
shall be fulfilled.
The classification of the external blinds shall be given according to 4.1.3.2.
4.1.3.2 Classes of wind resistance
The classes of wind resistance are given by the threshold test pressures specified in Table 1.
Table 1 — Classes of resistance to static pressure
Classes 1 2 3
40 70 110
Nominal wind pressure p (N/m²)
N
Safety wind pressure p (N/m²) 48 84 132
S

For folding arm awnings, class 2 is the minimum required.
NOTE The conditions to be met in order to fulfill 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 classification does not consider the anchoring of the external blinds on the building.
4.2 In the retracted position
4.2.1 General
Since some parts of external blinds – for example head boxes, guiderails – cannot be retracted, they have to
withstand in some cases very high wind speed. The resulting pressure on the product depends on:
 The installation condition,
 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 19.3.2.1).
NOTE As the criteria determining the resulting pressure applied to the fixed parts of external blinds are depending
on installation conditions (location, height, …), it is recommended to refer to National rules – if available – which give such
information on the basis of National wind speed map.
4.2.2 Determination
The determination shall be done by calculation when designing the external blind.
NOTE Since the external blinds covered by this standard have a huge variety it is not possible to describe a test
method for each product.

---------------------- Page: 11 ----------------------
oSIST prEN 13561 rev:2011
prEN 13561:2011 (E)
4.2.3 Performance requirement
All fixed parts of the external blinds, i.e. the parts that are not retracted when the external blind is in the
complete retracted position, shall be designed to withstand a minimum pressure of 800 Pa.
NOTE An example of determination of wind stress applied is given in Annex C.
5 Resistance to water pocket
5.1 General
This clause is only applicable to folding arm awnings, trellis arm awnings, Dutch awnings and Pergola
awnings
Under the action of precipitaton, the external blind may retain water forming a pocket of water. The external
blind shall withstand the corresponding load.
5.2 Determination
The determination shall be in accordance with the test method specified in EN 1933.
5.3 Performance requirement
For an incline of 14° corresponding to a slope of 25 % (or for a lower incline specified by the manufacturer),
the external blind in the fully extended position shall withstand the load created by a possible retention of
water by the fabric (no rupture), or the water shall drain off to avoid forming a pocket of water.
After releasing the load and drying of the fabric, the operating effort shall be maintained inside the class.
The instructions for use supplied by the manufacturer shall remind the necessity of retracting the external
blind in case of rain if the slope is less than 25 % or less than the value recommended by the manufacturer.
5.4 Performance classes
The performance classes are given in Table 2.
Table 2 — Resistance to water pocket — Performance classes
Classes 1 2
Flow 17 l/m²×h 56 l/m²×h
6 Resistance to snow load
Apart from fixed products (fixed Dutch awnings) for which the resistance to snow load is justified by
calculation according to the relevant regulations, internal blinds covered by this standard are not designed to
withstand snow load.
7 Operating effort
7.1 General
This clause does not apply to power operated products.

7.3.2 Specific case for folding arm awnings (see Figure 1)
The class of operating effort F shall be specified by two values:
c
F = {F , F }
C CP CN
where
 F is the maximum value of the peak force, needed to unlock the arms during the first round of the
CP
roller tube in retraction, the folding arm awning being in the fully extended position.
 F is the maximum value of the operating effort, needed during the remaining travel (retraction and
CN
extension).
The maximum values for F are given in Table 4.

8.1 General
This clause specifies geometrical characteristics of the operating mechanisms taking into account the comfort
of the operation.
8.2 Performances requirements
Gear operation
Gear with crank or winch handle shall have:
 a handle of a length R less than or equal to 0,20 m (R ≤ 0,20 m);
 a reduction ratio r of the gear less than 1:10 (average or mean reduction ratio when, for the same
gear, several reductions exist).
NOTE A reduction ratio of 1:10 means it is necessary to make ten turns of the crank to achieve one rotation of the
roller tube or axle.
Belt, cord or chain operation
These operating mechanisms shall have the minimal dimensions specified in the HPV diagrams (see Figure 2
and Figure 3).
