    Abstract - (Show below) - (Hide below)

    This European Standard is applicable to the selection of bolting for PN designated flanges in accordance with EN 1092 series and Class designated flanges in accordance with EN 1759 series. It specifies standards for dimensions, materials and technical conditions of delivery for bolts, stud bolts and nuts. The bolting of this standard is selected for the use together with the flanges EN 1092 series and EN 1759 series but not for general purpose. The selection of the materials is based on commonly used materials. It covers all pressure and temperature ranges of the general service of standard flanges.
