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15、, at the latest by December 2007, and conflicting national standards shall be withdrawn at the latest by December 2007.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

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
