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, treillis 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 γγγγ 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 criterias required.

110 NOTE 2 Class 0 corresponds to either performance not required or not declared or a product that does not fulfill the requirements of class 1.

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 αααα 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 fulfill 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 precipitaton, 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. The instructions for use supplied by the manufacturer will remind of the necessity of retracting the folding arm awning in the instance 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 7. Table 7 — 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 regulations existing in individual countries, products concerned in this standard are not designed to withstand snow load.

Operation mechanism shall also fulfill the requirements in clause 9. b
One direction movement and endless movement of the operating mechanism. Particular case for folding arm awning (see Figure 1) The class of operating effort Fc shall be specified by two values: FC = {FCP , FCN}
(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.

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 Operating mechanisms shall have minimal dimensions as given in the HPV diagrams (see Figures 2 and 3).

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.

− there shall be no visible defects : no onset of tearing the fabric, no splitting of seams, no permanent damage to front profile or guiderails;
− and, for manual operation, the value of operating effort shall be maintained within the limit of the initial class. Certain products are not designed to withstand obstruction of the curtain in situations a2, b1, c1 and c2 illustrated at Figure 4. They will not be subjected to the corresponding tests if the technical instructions of the manufacturer have a warning for the user of the risk of damage when the curtain is obstructed in these situations. The manufacturer shall ensure his installation instructions emphasise that the operating procedures shall be provided to the end user.
