20、surement of transmitted force 4.1Shutters with accumulating or retractable laths Verification of the accumulation condition Test aim: to measure - the speed of extension of curtain, in the last 0,40 m; - the displacement of the bottom rail in the direction of retraction under the action of a static
21、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 provided for the test in a rigid frame and mounted
22、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 of the leading edge of the curtain in the dire
23、ction 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.
