Thesenormative references are cited at the appropriate places in the text and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard, only when incorporated in it by amendment or revision.

This table is valid for all flangesfor which pressure temperature (p/T) ratings are given in prEN 1092-1. For flanges which have no p/T ratings(e.g. DN 700 and above), the tables may be used as a guide.All bolt materials can be used in the range of the p/T ratings given for the flanges. Restrictions due to theclassification shall be observed (see clause 4).WARNING Bold materials 4.6 and 6.8 are not intended for the use in the scope of the Pressure Equipment Directive.4Classification of bolt materialsThe classification of bolt materials as given in Table 1 is based on the comparison of the strengths of the flangematerial and the bolt material. The strength ratio r of the flange/bolt combination chosen is compared with thestrength ratio of the flange bolt combination used for the standard flange calculation (see annex A).For each flange material group the classification is done in three strength levels:? Low strength: The strength ratio of the chosen flange/bolt combination is less than that used in thestandard flange calculation.These bolts may be used for less severe service, e.g. for water service or in case of oversized flangedjoints. For definition of these service conditions, special experience is necessary otherwise a recalculation ofthe flanged joint shall be done.? Normal strength: The strength ratio of the chosen flange/bolt combination is similar (within defined limits)to that used in the standard flange calculation.These bolts may be used for all service in the range of the P/T-ratings unless there are other restrictions tothe contrary.? High strength: The strength ratio of the chosen flange/bolt combination is much more higher than that usedin the standard flange calculation.These bolts may be used in the same range like normal strength level bolting. During assembly however,care should be taken not to overstress the flanges (e. g. by means of torque control).Licensed Copy: Institute Of Technology Tallaght, Institute of Technology, Mon Apr 02
