13、0029:2010 (E) 4 1 Scope This European Standard specifies tolerances on dimensions and shape for hot-rolled non-alloy and alloy steel plates with the following characteristics: a) Nominal thickness: 3 mm t 400 mm; b) Nominal width: w 600 mm. Tolerances for products of width w 20 000 mm are required,

17、th normal (N) or special (S) flatness tolerances (see 7.2). 6 Tolerances on dimensions 6.1 Thickness 6.1.1 Tolerances on thickness are given in Table 1. Plates may be supplied with either: class A: for minus thickness tolerances depending on the nominal thickness; class B: for a fixed minus toleranc
18、e of 0,3 mm; class C: for a fixed minus tolerance of 0,0 mm; class D: for symmetrical tolerances.

19、0 000 mm shall be agreed at the time of enquiry and order (see 4.2, option e). 7 Tolerances on shape 7.1 Edge camber and out-of squareness For plate specified with normal edge camber and out-of squareness in the order, the edge camber and out of squareness shall be so that it is possible to inscribe
20、 a rectangle with the dimensions of the ordered plate within the delivered size. EN 10029:2010 (E) 8 For plate specified with limited edge camber and out-of squareness (G) in the order, the maximum values for edge camber and out of squareness shall be agreed at the time of enquiry and order (see 4.2
21、, option c). 7.2 Flatness 7.2.1 General Tolerances on flatness are given in Table 4 for normal tolerances (class N) and in Table 5 for special tolerances (class S). The plate shall be supplied with normal tolerances according to Table 4, only if otherwise specified in the order the plate shall be su
22、pplied with special tolerances (see 4.2, option d). Deviation from flatness shall be determined by measuring the distance between the plate and a straight edge (for details see 8.7). Straight edges of a length of 1 000 mm are used if the wave pitches (distance between the points of contact of the st
23、raight edge and the plate) are smaller than or equal to 1 000 mm. For longer wave pitches straight edges of a length of 2 000 mm are used. Deviations from flatness 2 mm shall not be considered as a wave and not be taken into account. NOTE It is pointed out that bad handling and storage can adversely
24、 affect the flatness of the product. The steel types according to Tables 4 and 5 are defined as follows: Steel type L: Products with a specified minimum yield strength Re 460 MPa, neither quenched nor quenched and tempered. Steel type H: Products with a specified yield strength Re 460 MPa and all gr
25、ades of quenched and quenched and tempered products. 7.2.2 Normal tolerances on flatness (class N) If the wave pitch (distance between the points of contact of the straight edge and the plate) is 1 000 mm the permissible deviation from flatness shall comply with the following requirements: For dista
26、nces between the points of contact of two waves between 300 mm and 1 000 mm the maximum flatness tolerance is 1 % for steel type L and 1,5 % of the wave pitch for steel type H, but not exceeding the values in Table 4.

29、mm and 1 000 mm the maximum flatness tolerance is 0,5 % of the wave pitch for steel type L and 1 % of the wave pitch for steel type H, but not exceeding the values in Table 5.

31、n case of dispute and be carried out at ambient temperature. 8.2 Thickness Thickness shall be measured at any point situated more than 25 mm from the transverse or longitudinal edges of the plate; other than locally ground area (see 6.1.2). For plates with untrimmed edges, the measuring points shall
32、 be agreed at the time of enquiry and order (see 4.2, option f). 8.3 Width Width shall be measured perpendicular to the major axis of the plate. 8.4 Length The length of the plate is the length of the shorter of both longitudinal edges. EN 10029:2010 (E) 10 8.5 Edge camber The edge camber value q is
33、 the maximum deviation between the longitudinal edge and the straight line joining the two ends of this edge. It is measured on the concave edge of the plate (see Figure 1).

34、f squareness The out-of squareness value u is the orthogonal projection of one transverse edge on one longitudinal edge (see Figure 2).

35、 plates shall be placed on a flat surface. Deviation from flatness shall be determined by measuring the deviation in distance between the plates and a straight edge of 1 000 mm or 2 000 mm long (see Tables 4 and 5) which may be placed in any direction. Only the part situated between the points of co
36、ntact between the straight-edge and the plate shall be taken into consideration. Deviations shall be measured at a point at least 25 mm from the longitudinal edges and at a distance a from the plate ends, depending on whether the normal tolerances or special tolerances apply respectively (see Figure
37、 3). Dimensions in millimetres Key a = 200 mm for normal flatness tolerances a = 100 mm for special flatness tolerances Figure 3 Measuring of flatness EN 10029:2010 (E) 12 Annex A (informative) List of product standards where dimensional standard EN 10029 is applied EN 10025-2, Hot rolled products o
