This standard is one of a series of standards for ductwork used for ventilation and air conditioning of buildings for human occupancy, and it has a parallel standard referring to dimensions of rectangular ducts. The position of this standard in the field of mechanical building services is shown in Figure 1. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 1998, and conflicting national standards shall be withdrawn at the latest by June 1998. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.

Introduction This 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 systems. Dimensions and tolerances for straight ducts given in this standard are in accordance with ISO 780719831 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. The dimensions given for duct fittings are based on document EUROVENT 2/41. 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 human occupancy. The wall thickness of ducts and fittings is not specified in this standard; strength and leakage are dealt with in prEN 12237. The corresponding standard for rectangular ducts is EN 1505. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies.

The tolerance is an absolute value without sign 3.7.4 clearance positive difference between the sizes of a female connector or duct and of a male connector 4 Dimensions and values for ducts The nominal diameter d, cross-sectional area Acand duct surface area Aiare given in Table 1. The nominal diameters also apply to fittings. Tolerances, deviations and clearances are given in clause 6.
