For flanges which have no p/T ratings (e. Restrictions due to the classification shall be observed (see clause 4).6 and 6. 4 Classification of bolt materials The classification of bolt materials as given in Table 1 is based on the comparison of the strengths of the flange material and the bolt material.EN 1515-2:2001 (E) EN 1515-1. the tables may be used as a guide. This table is valid for all flanges for which pressure temperature (p/T) ratings are given in prEN 1092-1. EN 10269.
Normal strength: The strength ratio of the chosen flange/bolt combination is similar (within defined limits) to that used in the standard flange calculation. e. Flanges and their joints .Part 1: Selection of bolting. All bolt materials can be used in the range of the p/T ratings given for the flanges. screws and studs (ISO 898-1:1999). 3 . care should be taken not to overstress the flanges (e. EN ISO 3506-1. The strength ratio r of the flange/bolt combination chosen is compared with the strength ratio of the flange bolt combination used for the standard flange calculation (see annex A). DN 700 and above). For definition of these service conditions.8 are not intended for the use in the scope of the Pressure Equipment Directive. 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 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 to the contrary. These bolts may be used for less severe service. by means of torque control).g. g. These bolts may be used in the same range like normal strength level bolting.

Classification: Bolt materials are set in relation to flange material groups and classified on the basis of their strength. Starting from the flange calculation model classification of the bolt material is done as given in this annex A.EN 1515-2:2001 (E) Annex A (informative) Basic information This annex describes the rules under which the tables of this standard have been developed. This material is combined with each bolt material given in EN 1515-1 and the stress ratio r is calculated for all temperatures.g.)
r: stress ratio for classification of the bolt material (see also clause 4)
r min: minimum value of all stress ratios of one flange material to one bolt material calculated over all temperatures. The results are evaluated for the classification of the bolt material. A.
r 20: stress ratio at 20 °C of one flange material to one bolt material. (See also prEN 1092-1 annex F: Determination of p/T ratings for flanges using EN materials. The p/T ratings of the flanges itself has been calculated with the lowest value of a material group.3 Calculation Calculation method of Stress Ratio r: gm = Smf / Smb = 225 / 300 g gm Smf Smb STf STb r = = = = = = = g = STf / STb r = gm / g = [225 / 300] / [STf / STb] Stress ratio for a flange/bolt combination at temperature Stress ratio for calculation model Flange material stress for flange calculation model at 20 °C (= 225 N/mm²) Bolt material stress for calculation model at 20 °C (= 300 N/mm²) Flange material stress at temperature (N/mm²) Bolt material stress at temperature (N/mm²) Stress ratio model/combination 17 . group 3E0) the material with the lowest stress at 20 °C has been selected for the calculations of this group (Cast stainless steel has not been used. as the stress values are too low).
