14、 (E) 3 Foreword This document (EN 1506:2007) has been prepared by Technical Committee CEN/TC 156 “Ventilation for buildings”, the secretariat of which is held by BSI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement
15、, at the latest by December 2007, and conflicting national standards shall be withdrawn at the latest by December 2007. This document supersedes EN 1506:1997. This standard is one of a series of standards for ductwork used for ventilation and air conditioning of buildings for human occupancy, and it
16、 has a parallel standard referring to dimensions of rectangular ducts. 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, Estoni

20、re 1 Position of EN 1506 in the field of mechanical building servicesIntroduction EN 1506:2007 (E) 5 Introduction This revised standard has been prepared by CEN/TC 156 to specify standardized dimensions and tolerances for ducts and duct fittings with circular cross-section, used in ventilation syste
21、ms. Dimensions and tolerances for straight ducts given in this standard are in accordance with ISO 7807: 19833 concerning recommended sizes. It is intended that the additional sizes (A) which are in use in some countries will be phased out and may be removed from a future edition of the standard. Th
22、e dimensions given for duct fittings are based on document EUROVENT 2/4 4. EN 1506:2007 (E) 6 1 Scope This European Standard specifies dimensions of ducts and duct fittings with circular cross- section. It applies to ductwork used in ventilating and air conditioning systems in buildings, subject to
23、human occupancy. The wall thickness of ducts and fittings is not specified in this standard; strength and leakage are dealt with in EN 12237 2. The corresponding standard for rectangular ducts is EN 1505 1. 2 Normative references The following referenced documents are indispensable for the applicati

25、For the purposes of this document, the terms and definitions given in EN 12792:2003 and the following apply. 3.1 nominal size (d, d1, d2, d3and d4) reference dimension used for designation, calculation and application of ducts and fittings d denotes the inner diameter of ducts and female ends. d1, d
26、2, d3and d4denote the outer diameters of male ends of fittings. 3.2 effective length of a fitting (l, l1, and l3) length by which a fitting contributes to the overall length of the air distribution system 3.3 effective length of a straight duct (L) length by which a straight duct contributes to the
27、overall length of the air distribution system 3.4 overlap (insertion) length (lp) length by which a fitting overlaps the duct EN 1506:2007 (E) 7 3.5 cross-sectional area (Ac) for ducts with circular cross-section the cross-sectional area Acis equal to Ac= d423.6 straight duct surface area (Ai) produ
