FN = ββββ ×××× p ×××× L ×××× H
(1) where L, H
is the width and height of blind as specified in EN 1932. p is the threshold value of wind test pressure in N/m2 corresponding to the class of wind resistance under consideration (see 4.4). β
is the conversion of the effect of distributed loading relative to those of test loads. It depends on the type of awning (see Tables 1 to 5).  β = 0,5 in the case of folding arm awning, trellis arm awning, projecting awning and marquisolette (see Tables 1 to 3).  β = 1 in the case of blind with lateral guiderail with or without tension system (see Tables 4 and 5). 4.3.3 Safety load FS For folding arm awning, trellis arm awning, pivot arm awning and marquisolette, a test shall be carried out using a safety load FS, 20 % greater than the nominal load FN, and for which no rupture of the product shall occur. FS = γγγγ ×××× FN with γγγγ = 1,20
(2) The value γ of 1,20 is judged to be representative of the extra load that the product shall be able to support between the appearance of allowable residual deformations (under the nominal load) and the risk of breaking. It takes into consideration that a retractable external blind is not supposed to be extended permanently and shall be retracted if the wind speed becomes higher than the value stated in the technical instructions of the manufacturer corresponding to the class of wind resistance of the blind. Tables 1 to 5 give, for the different blinds, the sequences of loading and the corresponding performances criteria required. SIST EN 13561:2004+A1:2009

4.4 Classes of wind resistance The classes of wind resistance are given by the threshold values of nominal test pressure p, specified in Table 6; Table 6 — Classes of wind resistance Classes 0 1 2 3 Nominal test pressure p (N/m²) < 40 40 70 110 Safety test pressure 1,2 p (N/m²) < 48 48 84 132
Beaufort scale 4 5 6 V (km/h) (maximum values)
49 Pressure p (N/m²)
NOTE 2 Class 0 corresponds to either performance not required or not declared or a product that does not fulfil the requirements of class 1. NOTE 3 The test pressure p is linked to the dynamic pressure q due to the wind to be considered by the following relation.
p = αααα q
with αααα = Cpe - Cpi
(3) and Cpe is the pressure coefficient on external face of blind. Cpi is the pressure coefficient on internal face of blind. The coefficient α depends on the type of product and its position. For folding arm awnings, α = 0,6 NOTE 4 For folding blinds, the maximum dynamic pressure q under consideration corresponds to the maximum wind speed compatible with the extended position of the blind. NOTE 5 The conditions to be met in order to fulfil the performance requirement are defined for static loads and do not consider the dynamic effect of repeated loads to which the fabric and the arms are submitted in a real situation. For these reasons, class 2 or class 3 is a general recommendation. 5 Resistance to water pocket 5.1 General This applies to folding arm awning, trellis arm awning and Dutch awning. Under the action of precipitation, the external blind is susceptible to the retention of water forming a pocket of water and shall withstand the corresponding load. 5.2 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 lesser incline specified by the manufacturer), the fully extended blind shall withstand the force 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 force shall be maintained inside the class. SIST EN 13561:2004+A1:2009

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 regulations existing in individual countries, products concerned in this standard are not designed to withstand snow load. 7 Operating effort 7.1 General Does not apply for power operated products. The effort FC necessary to set the curtain in motion in retraction or extension, and tilting the laths (for tilting louvre arrays) is a function of the type of operation. 7.2 Determination Shall be in accordance with the test methods specified in EN 13527. 7.3 Performance requirement and operating effort classes Operating effort FC shall not exceed the values in Table 8. Table 8 — Maximum values Fc for operating effort TYPES OF OPERATION Fc N

Operation mechanism shall also fulfill the requirements in clause 9. b
One direction movement and endless movement of the operating mechanism.

(4) where FCP
is the maximum value of the peak force, needed to unlock the arms during the first round of the roller tube in retraction, the folding arm awning being in the fully extended position. FCN is the maximum value of the operating force, needed during the rest of travel (retraction and extension). The maximum values for Fc are given in Table 9.

Misuse operations are related to the displacement of the curtain and to the tilting of the laths. 9.1.2 Displacement of the curtain  Rough operation Rough operation occurs during extension and retraction.  Forced operation Forced operation occurs in the direction of extension and retraction, the curtain being either stopped or blocked in extended or retracted position, or blocked in an intermediate position. Figure 4 illustrates the six possibilities of forced operations. SIST EN 13561:2004+A1:2009

Figure 4 — Illustration of the six possibilities of forced operation In the case of the folding arm awning, only the situations a1 and b2 have to be taken into account.  Reversed operation Reversed operations are only applicable to roller blinds or to products using a rolling mechanism for extension or retraction. For these products, operation in situation a1 or b2 illustrated Figure 4, is a reversed operation when the movement in the opposite direction is possible with an effort less than the limit of the class of operation. If the movement is not possible, it is a forced operation. Reversed operation occurs on extension with the curtain fully extended and on retraction with the curtain fully retracted. 9.1.3 Tilting of the laths  Rough operation Rough operation is not possible, the conditions defining its occurrence are not likely to occur (no excessive speed, no inertia of laths).  Forced operation Forced operation occurs in both closed positions which are the result of tilting the laths in both directions from the open position.  Reversed operation Not applicable.

If the operating mechanism is equipped with a system which limits the force or the torque (see clause 11), the values of PF and CF are those given by this system. d
For power operated operations, the effort to be applied is that produced by the motor.

NOTE A mechanical brake is a brake applied mechanically by stored energy (spring force) until released with an external sustained electrical power supply under the control of the operator or automatically. * Grease and oil traces There shall be no visible traces of grease and oil. 10.4 Classes of endurance Table 12 gives the endurance cycles corresponding to the three endurance classes specified.
