18、tics: a) Nominal thickness: 3 mm t 400 mm; b) Nominal width: w 600 mm.

21、 B, C or D (see 6.1); with trimmed or untrimmed edges (NK) (see 6.2.2); with normal or limited edge camber and out-of-squareness (G) (see 7.1); with 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. P

22、lates may be supplied with either: class A: for minus thickness tolerances depending on the nominal thickness; class B: for a fixed minus tolerance of 0,3 mm; class C: for a fixed minus tolerance of 0,0 mm; class D: for symmetrical tolerances.

24、fied 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 a rectangle with the dimensions of the ordered plate within the delivered size.

25、 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, 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 spe

26、cial 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 supplied with special tolerances (see 4.2, option d). Deviation from flatness shall be determined by measuring the distance between the plat

27、e 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 straight 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.

28、 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 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 spe

29、cified 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 grades of quenched and quenched and tempered products. 7.2.2 Normal tolerances on flatness (class N) If the wave pitch (distance between the

30、 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 distances 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

31、 % of the wave pitch for steel type H, but not exceeding the values in Table 4.

36、 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 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

37、 plate. 8.4 Length The length of the plate is the length of the shorter of both longitudinal edges. BS EN 10029:2010EN 10029:2010 (E) 10 8.5 Edge camber The edge camber value q is the maximum deviation between the longitudinal edge and the straight line joining the two ends of this edge.

Deviation from flatness shall be determined by measuring the d

40、eviation 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 contact between the straight-edge and the plate shall be taken into consideration. Deviations shall be meas

41、ured 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 3).
