4 5. Tightening Torque method The bolts shall be tightened using a torque wrench offering a suitable operating range. Hand or power operated wrenches may be used. Impact wrenches may be used for the first step of tightening for each bolt. a) a first tightening step: the wrench shall be set to a torque value of about 0,75 Mr,i with Mr,i =. Mr,2 or Mr, first step shall be completed for all bolts in one connection prior to commencement of the second step;. b) a second tightening step: the wrench shall be set to a torque value of 1,10 Mr,i with Mr,i = Mr,2. or Mr,test.

Tightening torque Mr (=1,10 Mr,i) showed on nuts packaging has to be applied using calibrated torque wrenches with accuracy of 4% according to EN ISO 6789 by rotation of the nut; different tightening procedures have to be approved by experimental tightening tests under site conditions as specified in annex H.

5 Of European Standard EN 1090-2: 2008+A1:2011. Combined method Tightening by the combined method comprises two steps: a) a first tightening step, using a torque wrench offering a suitable operating range. The wrench shall be set to a torque value of about 0,75 Mr,i with Mr,i = Mr,2 or Mr,1 or Mr,test. This first step shall be completed for all bolts in one connection prior to commencement of the second step;. b) a second tightening step in which a specified part turn is applied to the turned part of the assembly. The position of the nut relative to the bolt threads shall be marked after the first step, using a marking crayon or marking paint, so that the final rotation of the nut relative to the thread in this second step can be easily determined. Total nominal thickness "t" of parts to be Further rotation to be applied, during the connected (including all packs and washers) second step of tightening d = bolt diameter Degrees Part turn t<2d 60 1/6.
