Tests to be carried out to determine the ability of shutters and blinds to resist abnormal use of their operating mechanisms in terms of rough, forced or reversed operation are defined in this Standard. Applicable to the following: External blinds: folding arm awnings, trellis arm awnings, vertical roller awnings, pivot arm awnings, facade awnings, roof light awnings, marquisolettes, verandah and conservatory awnings, dutch awnings, insect screen awnings and louvre arrays. Internal blinds: Internal roller, vertical, pleated and venetian blinds and darkening blinds. Shutters: External venetian blinds, roller shutters (vertical or projected) venetian shutters (vertical or projected) flat-closing concertina shutters, sliding panel shutters.
