Example: Bulb flat EN 10067-2003 10. 5 Dimensions Ho
21、t-rolled bulb flats complying with this European Standard shall be delivered with the dimensions given in table 1 and illustrated in figure 1. NOTE. The geometric properties, the data on the cross-section, and the surface area are derived from the nominal dimensions. 6 Tolerances on shape and dimens
22、ions 6.1 Width and thickness The width and thickness tolerances shall be as given in table 2. The width shall be measured on the longer side of the leg. 6.2 Tolerance for out of squareness of weld edge The angle by which the weld edge deviates from the vertical (u) shall not exceed 4 (see figure 2).
23、 6.3 Corner radius The maximum values for the corner radius r 1 shall be as given in table 3. 6.4 Length 6.4.1 Hot-rolled bulb flats shall be delivered in lengths up to and including 18 m. Lengths greater than 18 m shall be agreed at the time of ordering. 6.4.2 The length tolerances shall be mm. Clo
24、ser 0 +100 length tolerances shall be specially agreed at the time of ordering. 6.5 Straightness The straightness tolerance q shall be 0,0035 L. The dimension q shall be measured as illustrated in figure 3 along the entire length L. 7 Tolerance on mass The mass tolerances shall be: % of the total ma
25、ss for deliveries of 5 t or more, 22 +6 and % of the total mass for deliveries of less than 5 t. 22,7 +8 The mass deviation shall be the difference between the actual delivery mass and the theoretical mass. The theoretical mass shall be calculated from the data in table 1 and the ordered length in m
26、etres. NOTE. The masses given in table 1 are derived from the sectional areas using a density of 7,85 kg/dm 3 .Page 4 EN 10067 : 1996 BSI 1997 Figure 1. Shape of bulb flat Figure 2.
