EN10249-1, Cold formed sheet piling of non alloy steels Part1: Technical delivery conditions. 3 Control of tolerances General 3.1 All the measurements are taken outside of the zone deformed by cutting at a distance from the ends of at least250mm. 3.2 The dimens
23、ions are measured by instruments of appropriate accuracy. 4 Height of profiles The tolerances on the height of sheet piles are given in Table 1. 5 Width of profiles The tolerances on the width of profiles are as follows: individual sheet pile: 2% of the nominal width; pair of interlocked sheet piles
24、: 3% of the nominal width. 6 Wall thickness of profiles The tolerances on the wall thickness of the profiles shall comply with the requirements of Table2 of EN10051, for a nominal width of strip and sheet over1800mm. 7 Straightness of profiles 7.1 General The controls of the profile straightness (me
25、asurement of bow-heights corresponding to bending and curving) shall be carried out on a pile which freely lies on a plane surface according to the following Figure 1 and Figure 2. For Z-sheet piles, the controls are carried out on an interlocked pair of sheet piles, and if appropriate, on a welded
26、pair of sheet piles when they are delivered welded. 7.2 Bending The bow-height S in the horizontal plane of the sheet pile is the distance between the cord and the arc formed by the sheet pile edge (see Figure 1). The bow-height (S) shall bek 0,25% L. 7.3 Curving The bow-height C in the vertical (pe
27、rpendicular) plane of the sheet pile is the distance between the sheet pile edge in its middle and the reference plane surface (see Figure 2). The bow-height (C) shall bek 0,25% L. 7.4 Twisting One sheet pile end being fixed, the dimension (V) which characterizes the twisting is measured at the free
28、 end of the sheet pile with regard to the reference plane (see Figure 3). The dimension (V) shall not exceed2% L with a maximum of100mm. 8 Length The normal tolerance is 50mm. A reduced tolerance may be agreed at the time of the enquiry and order. Option1, see13.2. 9 Squareness of ends The total dev
29、iation between the highest and the lowest point of the cutting plane (t) shall not exceed2% of the width of the profile, measured perpendicular to the longitudinal axis. When the sheet piles are delivered in seamed pairs by means of welds all along the lock, the upper end shall not present a misalig

(see Figure 5) may be agreed at the tim
32、e of the enquiry and order. Option2, See13.3 11 Mass of profiles Compared with the calculated mass (product of ordered pile length by mass per linear metre of pile according to section tables of the producers), the actual mass may show a deviation of not more than 7% relative to the mass of the tota
33、l delivery. A reduced tolerance may be agreed at the time of the enquiry and order. Option3, see13.4. 12 Joints, overlapping The form of the joints/overlapping is at the manufacturers discretion. If cold formed sheet piles with joints are delivered, the interlocks shall have adequate free play, so t
34、hat the piles can be fitted into each other. This is verified by using two samples500mm long. 13 Options 13.1 Options are available to the purchaser which shall be specified as required at the time of the enquiry and order (see4.2 EN10249-1). 13.2 Option1 A reduced tolerance for the length of profil
