19、n of retraction under the action of a static force of 150 N. Dimensions: the test is carried out for a height and width of product given by the manufacturer. If the accumulating condition occurs, it will be satisfied for all greater heights and smaller widths. Test preparation: the product is provid
20、ed for the test in a rigid frame and mounted according to the installation instructions of the manufacturer. It is presented vertically and extended up to a distance of 0,16 m from the fully extended position. Test: a load of 150 N shall be applied to the middle of the bottom rail or at mid-height o
21、f the leading edge of the curtain in the direction of retraction. The displacement obtained shall be recorded. The average speed of extension of the curtain shall be measured in the last 0,40 m.

22、cumulating test for the laths Roller shutter 4.2 Roller, sliding shutters, external venetian blinds, flatclosing concertina shutters Test aim: measurement of the transmitted force, when the accumulating condition is not satisfied. Dimensions: for a given motor, the test is carried out for the minimu
23、m dimensions specified by the manufacturer. Test preparation: the product is provided for the test in a rigid frame and mounted according to the installation instructions of the manufacturer. It is presented vertically so that the travel of the curtain is limited to 0,40 m (first measurement) and to
24、 0,10 m (second measurement) from its full extension (see Figures 1 and 2).Page 7 EN 12045:2000 %6, Test: a force measuring device, dynamometer or other, accurate to 3 % is placed at the middle of the bottom rail (in the case of roller shutters or venetian blind) or at a mid-height of the leading ed
25、ge (in case of sliding panel shutters or flat closing concertina shutter) in the direction of retraction. The curtain being operated in the direction of extension, the effort required to immobilize the curtain in recorded. The transmitted force is the highest value of the two measurements recorded.
26、4.3 Wing shutters Test aim: measurement of the transmitted force and the amount of distance between the leaves out of phase (see Figure 3). Dimensions: for a given motor, the test is carried out for the minimum dimensions specified by the manufacturer. Test: the test is carried out as described in 4
27、.2 (force measurement device placed at the middle of the edge of the “closing” leaf and measurements at 0,40 m and then 0,10 m of the full extension position). Furthermore, it is verified, when the “closing” leaf is at 0,40 m of the fully extension position, the previous leaf has a minimum gap of 0,
28、10 m, the measurement being between edges of leaves (see Figure 3). 4.4 Projection awnings, guided blinds and conservatory awnings Test aim: measurement of transmitted force at the extended position. Dimensions: the test is carried out at the minimum dimensions specified by the manufacturer: for fol
29、ding and trellis arm awnings, for each type of arm, for other awnings and blinds, for the heaviest front profile. Test preparation: the awning or blind provided on a rigid frame and mounted according to the manufacturers installation instructions and extended until the front profile is situated 0,40
30、 m (first measurement) and to 0,10 m (second measurement) from the fully extended position, arms in the horizontal position in the case of pivot arm awning. Test: a dynamometer, accurate to 3 %, is located at the middle of the front profile parallel to the side edge of the fabric and at right angles
31、 to the front profile or roller tube. The awning or blind is extended, the force necessary to maintain the front profile in a stationary position shall be recorded. The transmitted force is the highest value of the two measurements recorded. 4.5 Conservatory awnings Test aim: measurement of the transmitted force at each idling roller and the distance between these and the front profile. Dimensions: the test is carried out with the heaviest front profile at the minimum size of the product as specified by the manufacturer.
