<p>Hello Paul,</p> <p>we have a DIN Standard that governs the tolerances independently of the measuring units. The tolerances dependend upon the length of the measured element. For length up to 3 m the allowed tolerance is <span style="font-size:11.0pt;line-height:115%;font-family:'Calibri','sans-serif';">±</span>12 mm, 3 to 6 m: <span style="font-size:11.0pt;line-height:115%;font-family:'Calibri','sans-serif';">±</span>16mm; for 6 to 15 m: <span style="font-size:11.0pt;line-height:115%;font-family:'Calibri','sans-serif';">±</span>20 mm; 15 to 30: <span style="font-size:11.0pt;line-height:115%;font-family:'Calibri','sans-serif';">±</span>24 mm; >30 m: <span style="font-size:11.0pt;line-height:115%;font-family:'Calibri','sans-serif';">±</span>30 mm.</p> <p>Steel structure tolerances are much smaller: 1 mm for length up to 2,000mm and 6 mm at 16,000 mm in steps of one mm in-between.</p> <p>If there are 5 elements in a row the total length is the basis. If you have 5 elements of 6 m length each has a tolerance of <span style="font-size:11.0pt;line-height:115%;font-family:'Calibri','sans-serif';">±</span>16 mm, the tolerance of the row is <span style="font-size:11.0pt;line-height:115%;font-family:'Calibri','sans-serif';">±</span>30 mm<span style="font-size:11.0pt;line-height:115%;font-family:'Calibri','sans-serif';">.</span>Steel structure tolerances are much smaller. Steel structure tolerances are much smaller. <span style="font-size:11.0pt;line-height:115%;font-family:'Calibri','sans-serif';">±</span>1 mm for length up to 2000mm and <span style="font-size:11.0pt;line-height:115%;font-family:'Calibri','sans-serif';">±</span>6 mm at 16,000 mm in steps of one mm.</p> <p>Smaller tolances can be contractually agreed.</p> <p>Thas has been just one example. All possible deviations are regulated.<br />Regards, Volker</p> <p> </p>
