21、distance from the ends of at least 250 mm. 3.2 The dimensions 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 pil

22、e: I 2 % of the nominal width; - pair of interlocked sheet piles: f 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 table 2 of EN 10051, for a nominal width of strip and sheet over 1 800 mm.

23、0249-2 : 1995 7 Straightness of profiles 7.1 General The controls of the profile straightness (measurement 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 figures 1 and 2. For Z-sheet piles, the contr

24、ols are carried out on an interlocked pair of sheet piles, and if appropriate, on a welded 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

25、 1). The bow-height (S) shall be I 0,25 5% L. 7.3 Curving The bow-height C in the vertical (perpendicular) 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 be I 0,25 % L. 7.4 Twisting One sheet

26、pile end being fixed, the dimension (V) which characterizes the twisting is measured at the free end of the sheet pile with regard to the reference plane (see figure 3). The dimension (V) shall not exceed 2 % L with a maximum of 100 mm. 8 Length The normal tolerance is f 50 mm. A reduced tolerance m

Option 1, see 13.2. 9 Squareness of ends The total deviation between the highest and the lowest point of the cutting plane (t) shall not exceed 2 % of the width of the profile, measured perpendicular to the longitudinal axis. When the sheet piles ar
