Foreword This European Standard has been prepared by Technical Committee CEN/TC 33,“Doors, windows, shutters and building hardware”, the secretariat of which is held by AFNOR. 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of an identical text or by endorsement, at the latest by May 2000, and conflicting national standards shall be withdrawn at the latest by May 2000. 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. This standard is one of a series of standards for doors. The tolerance classifications relate to measurement methods published in EN 952. No existing European Standard will be superseded.Introduction The general flatness of a door leaf may be important in satisfying both visual and performance requirements. Local flatness, as defined in this standard, is only concerned with the visual effect of surface undulations over small areas of the face of a door leaf. Moreover it is important to recognize that the visibility of such undulations depends upon the degree of light reflection, based upon the level of gloss and the angle of light. Under extreme gloss/light conditions, undulations of as lttle as 0,025 mm may be discerned. This standard therefore provides local flatness values which are considered to be practical and reasonable. 1 Scope This standard gives the tolerances limits for general and local flatness of door leaves. It applies to door leaves which are supplied without, and independent of, any frames. It does not apply to the leaves of door sets. NOTE : Compliance with the tolerance limits given in this standard does not imply that this would necessarily produce a perfect fit between door leaves and frames.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. EN 952:1 999 Door leaves – General and local flatness – Measurement method.3 Definitions For the purposes of this standard the following definitions apply. 3.1 twist spiral distortion in the plane of a door leaf 3.2 bow curvature in the direction of the height of a door leaf 3.3 cup curvature in the direction of the width of a door leaf 4 Classification Tolerance classes are based on permitted deviations of general flatness, expressed as twist, bow and cup and on local flatness. To qualify for a particular tolerance class, the deviations when measured in accordance with EN 952:1999 shall not exceed the appropriate permitted deviations given in Tables 1 and 2.
