This European Standard specifies the requirements which internal blinds shall fulfil when fitted to a building. It deals also with the significant machinery hazards relating to construction, transport, installation, operation and maintenance of the internal blinds (see list of significant hazards in Annex B). It applies to the internal blinds, whatever their design and nature of the materials used, as listed below: - venetian internal blind: free hanging, guided, non-retractable; - roller internal blind: free hanging, side guided, with tensioned fabric; - vertical internal blind: free hanging, with top and bottom track, and sloping headrail; - pleated internal blind: free hanging and guided. These products may be operated manually, with or without compensating springs, or by means of electric motors (power operated products). This standard does not apply to Roman Shades, Austrian, Festoon, Pinoleum, laterally moving pleated internal blinds, insect screens or internal blinds in sealed glazed units. Noise aspects are not treated in this standard because this is not considered a safety issue. This standard is not applicable to internal blinds which are manufactured before the date of publication of this standard.
