3 Terms and definitions
For the purposes of this European Standard, the terms and definitions given in EN 10079:1992 apply.
4 Designation
The designation of hot-rolled round steel bars shall comprise:
— the term round bar
— the number of this European Standard (EN 10060);
— dimensions in mm (diameter and length (M, F or E, see Table 4)):
— tolerance class P, if necessary;
— the number of the quality standard and the steel name or steel number of the ordered steel.

5 Dimensions
Hot rolled round bars for general purposes complying with this European Standard shall be delivered with the specified dimensions range given in Table 1 and illustrated in Figure 1. The preferred dimensions are pesented in Table 1.
Hot rolled round bars for precision purposes complying with this European Standard shall be delivered with the specified dimensions range given in Table 1 and Table 2.
6 Tolerances on dimensions and shape
6.1 Diameter (c
The deviation from nominal diameter (c shall be within the tolerance given in Table 1 and Table 2.
NOTE In the Table 1 there are two tolerance classes, normal and precision (P).
6.2 Length (L)
Depending on the type of length the bars shall be cut to lengths within tolerances given in Table 4.
6.3 Straightness (q)
The straightness shall comp4y with the requirements given in Table 3. The requirements for waviness
may be agreed at the time of enquiry and order.
6.4 Ovality
The deviation for roundness shall not exceed 75% of the tolerance range given in Table 1 and Table 2.
7 Measurement
7.1 Diameter
The diameter shall be measured at any point situated at least 100 mm from the end of the bar. Shearing may deform the bar ends. The condition of the ends may be agreed at time of enquiry and order.
7.2 Length
The length shall be measured as the longest length of the bar.
7.3 Straightness
The straightness shall be measured over the total length (L) of the bar.
7.4 Ovality
The ovality shall be measured as the difference of the greatest diameter and the smallest diameter in the same plane perpendicular to the axis of the bar. The ovality shall be measured at any point situated at least 100 mm from the end of the bar.EN 10060-2003 pdf download.
