5 Dimensions
Hot rolled square 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 presented in Table 1.
6 Tolerances on dimensions and shape
6.1 Size(a)
The deviation from nominal size (a) shall be within the tolerance given in Table 1.
6.2 Length (L)
Depending on the type of length square bars shall be cut to lengths within tolerances given in Table 3.
6.3 Corner radius (,
The corner radius (,) shall comply with the requirements given in Table 2.
6.4 Straightness (q)
The straightness shall comply with the requirements given in Table 2. The requirements for waviness
may be agreed at the time of enquiry and order.
6.5 Twist
Twist shall comp’y with the requirements given in Tab’e 2.
6.6 Out-of-squareness (U)
Out-of squarer)ess (U) shall be within the tolerance given in Table 2.
7 Measurement
7.1 Size
The size shall be measured at any point situated at least 100 mm from the end of the square 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 square bar.
7.3 Corner radius
The radius shall be measured by a radius gauge at any point situated at least 100 mm from the end of the square bar.
7.4 Straightness
The straightness shall be measured over the total length (L) of the bar.
7.5 Twist
The square bar shall be placed on a horizontal surface with one side at one end pressed against the surface At the opposite end of the square bar the difference in height of the two lower corners from a horizontal surface shall be measured.
7.6 Out-of-squareness
Out-of-squareness shall be measured according to Figure 2 as the difference u on the nominal size a.EN 10059-2003 pdf download.
