1, This DIN Standard for a single series of flanges specïfies requirements for circular steel flanges in PN designations PN 2.5 to PN 100 and nominal sizes from DN 10 to DN 4000. This standard specifies the flange types and their facings, dimensions. tolerances. threading. bolt sizes. flange jointing face surface finish. marking. materials. pressure/ temperature ratings and approximate flange masses. This standard does not apply to flanges made from bar stock by turning, or to flanges of types 11, 12 and 13 made from plate material.
2, Normative references This DIN Standard incorporates by dated or undated reference provisions from other pubIicatons. These normative references are cited at the appropnate places in the text and the pubIicatons are listed hereafter. For dated references, subsequent amendments to or revïsïons of any of these publications appy to this European Standard only when incorporated in t by amendment or revision. For undated references the atest edition of the publication referred to appiies (inciuding amendments).
