    26、 Deviations from straightness, hsand ht,shall be measured as shown in Figure 1 with the hexagonal bar placed on a horizontal base plate so that its mass decreases the deviation. The straightness tolerances are specified in Table 4. (The straightness tolerance htapplies to the whole length, e.g. for

    27、a length of 6 m the maximum deviation from straightness htis the value given in the table multiplied by 6 m). For hexagonal bars with width across flats less than 10 mm, the straightness tolerances shall be agreed upon between supplier and purchaser. DIN EN 754-6:2008-06 EN 754-6:2008 (E) 6 The stra

    28、ightness tolerances apply to hexagonal bars with width across flats 10 mm and greater in all tempers except O and Tx51.
