17、hutters and blinds to resist abnormal use of their operating mechanisms in terms of rough, forced or reversed operation. It applies to the following products: - Internal blinds: Internal venetian blinds, roller, vertical and pleated blinds and darkening blinds. - External blinds: Folding arm awnings
18、, trellis arm awnings, vertical roller awnings, pivot arm awnings, marquisolettes, faade awnings, roof light awnings, verandah or conservatory awnings, dutch awnings, insect screen awnings and louvre arrays. - Shutters: External venetian blinds, roller shutters (vertical or projected), venetian shut
19、ters (vertical or projected), flat-closing concertina shutters, concertina shutters, sliding panel shutters. Shutters with a projection system are also covered. 2 Normative references The present European Standard incorporates by dated or undated reference, provisions from other publications. These

24、duct, blind or shutter, is submitted for test in its normal usage position, fully equipped, with the necessary operating systems and mechanisms, systems for guiding the curtain and projection system where applicable. The complete assembly is mounted on a test rig according to recommendations in the
25、manufacturers technical instructions, which consists of: - for blinds and shutters with a vertical curtain, a rigid frame simulating the opening. The frame allows, if necessary, locking of the curtain or its projection. The support piece shall be horizontal. - for projecting shutters with a vertical
26、 curtain, on a rigid support which simulates the wall, faade or roof, on which the test product is fixed using the positions recommended by the manufacturer and erected in compliance with the technical instructions (e.g. use of brackets) and according to the angle(s) specified in EN 13527: 1999. - f
27、or sloping or horizontal products, on a rigid support, allowing it to be tilted to the minimum and maximum angles laid down in the manufacturers technical instructions. After the blind or shutter has been mounted, check that it is operating normally by carrying out a complete operation: extention, r
28、etraction, locking, tilting the laths (where applicable) and all other options with which the product is equipped, with particular attention to the setting of the limit stops. 9 BSI 08-2000 Page 6 EN 121 94:2000 4.3 Nature of tests The testing of the operating mechanism to determine the possibility
29、of misuse. 4.3.1 Reminder 4.3.1.1 Misuse relating to the curtain - rough operation is only possible if the moving part has significant mass and can reach excessive speed. - forced operation may occur either at the fully extended or retracted position or at an intermediate position when obstructed (s

They will not be subjected to the corresponding tests if the operating procedure() does not warn the user of the risk of damage when the curtain is obstructed in these situations. - reversed operation i
32、s only possible if continued operation within the limits of the operating force of the class: 0 once the product is fully extended, leads to the retraction of the curtain; 0 once the product is fully retracted, leads to the extension of the curtain. or Reversed operation only refers to rolling blind

39、rs); - rotational operation: - gear with crank handle; - - winch with cord, cable or tape; wand, rod or knob (only for tilting the laths of internal blinds); - power operated mechanism. 4.4 Efforts to be applied - Force P for linear operation. - Torque C for rotational operation. - Efforts developpe

43、the curtain A tolerance of f10 mm is allowed. 4.7 Requirements for conducting the tests - The tests described in the following paragraphs are carried out a number of times equal to 0,5 % of the endurance cycles for the class of the product, number designated by N for the following. - During the forc
44、ed operation test, the force P, or the torque C, is applied for 5 s. The curtain shall be operated in the opposite direction as is necessary to achieve the start conditions before reapplying P, or C,. In the case of operation by crank handle and for Situations bl and CI (see Figure l), for which the
45、 value of C, is not achieved at the end of three turns of the handle, the test is carried out in the following manner: - carry out the three turns of the crank handle then return to the initial position; - carry out the procedure N times; - At the end of each test, record any possible damage.
