This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s) For relationship with EU Directive(s), see informative !Annex ZA, which is an integral part" of this document This European Standard is part of a series of standards dealing with internal blinds and shutters for buildings as defined in EN 12216 This European Standard specifies the requirements for internal blinds, the levels of performance and, where applicable, the associated classes It is completed by test standards as well as by the standards referring to specific performance requirements Annex A and C are informative Annex B is normative According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom BS EN 13120:2009+A1:2014 EN 13120:2009+A1:2014 (E) Introduction The performances given in this European Standard, which illustrate suitability for use, are required for internal blinds detailed in the scope (intrinsic performances) Other performances are only required as a complement (specific performances) for specific products and are described in other European Standards Some important specific performances relating to thermal and visual aspects are described in EN 14501 These standards state classifications and test methods for the following properties: — for thermal comfort: — solar factor (see Clause 11 of the present standard); — secondary heat transfer factor; — direct solar transmittance; — for visual comfort: — glare control; — night privacy; — visual contact with the outside; — opacity control; — daylight utilisation; — rendering of colours NOTE Health and Safety regulations require that the workplace receives as much natural light as is reasonably practical (see EU Directive 89/654/EEC) and protection of operators working with VDU screens against glare and reflected light (see EU Directive 89/391/EEC) NOTE Reaction to fire of internal blinds is not covered by this standard The performance of the products shall be evaluated according to the relevant standards (e.g EN 13772) Minimal performance may be required by national regulations A list of these documents is given in the Bibliography This European Standard is a type C standard as stated in EN ISO 12100 The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this document When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard With the aim of clarifying the intentions of the standard and avoiding doubts on reading, the following assumptions were made related to power operated products: — negotiations occur between the manufacturer and the purchaser concerning particular conditions for use and places for use such as nursery schools or buildings for disabled people which need specific risk analysis; BS EN 13120:2009+A1:2014 EN 13120:2009+A1:2014 (E) — the risk analysis carried out in this European Standard and the significant hazards listed in Annex B presume a normal use or normally predictable use e.g which excludes deliberate and conscious risks taken by the user (see Interpretative Document “Safety in use” of EU Construction Products Directive) BS EN 13120:2009+A1:2014 EN 13120:2009+A1:2014 (E) Scope !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 internal blinds (see list of significant hazards in Annex B) It applies to internal blinds, whatever their design and the nature of the materials used, as listed below: — venetian blind: free hanging, guided, non-retractable; — roller blind: free hanging, side guided, with tensioned fabric; — vertical blind: free hanging, with top and bottom track, sloping headrail; — pleated and honeycomb blind: free hanging, guided, laterally moving, tensioned; — Roman Shades; — Austrian / Festoon blinds; — panel blinds; — plantation shutters; — roll-up blinds 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 draperies and insect screens It does not apply to blinds in sealed glazed units with the exception of requirements related to protection from strangulation NOTE Insect screens may be installed either internally or externally However, because they are always exposed to external conditions in use ( windows/doors opened), insects screens are covered by EN 13561 applying to external blinds and awnings 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."
