BS 10029:2010 pdf download – Hot-rolled steel plates 3 mm thick or above — Tolerances on dimensions and shape
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 < 600 mm cut or slit from plate should be agreed between manufacturer and purchaser at the time of enquiry and order. This European Standard applies, but is not limited, to steel grades defined in EN 10025-2 to EN 10025-6:2004+A1:2009, EN 10028-2 to EN 10028-6, EN 10083-2 and EN 10083-3, EN 10084, EN 10085,EN 10149-2 and EN 10149-3, EN 10207 and EN 10225 (see also Annex A). It does not apply to stainless steels. This European Standard does not include round plates, custom-made plates, chequer or bulb plate for flooring and wide flats. 2 Normative references The following referenced documents are indispensable for the application of this document.

Plates ordered according to this European standard shall be delivered as follows: tolerance class A for thickness unless otherwise stated (see 6.1, Table 1); trimmed edges; normal edge camber and out-of-squareness (see 7.1); normal tolerances for flatness, class N (see 7.2, Table 4). If no information concerning points a) to f) of 4.1 is given by the purchaser, the supplier shall refer back to the purchaser. 4.2 Options A number of options are specified in this European Standard and listed below. If the purchaser does not indicate his wish to implement any of these options, the supplier shall supply in accordance with the basic specification of this European Standard (see 4.1): a) if thickness tolerance class B, C or D is required, include B, C or D in the order designation (see Clause 5 and 6.1); b) if plate with untrimmed edges is required, include NK in the order designation (see 6.2.2); c) if plate with limited edge camber and out-of-squareness is required, include letter G in the order designation and define the required maximum values for edge camber and out-of-squareness (see 7.1); d) if plate with special flatness tolerances is required, include the letter S in the order designation (see 7.2.1 and Table 5); e) if plates with a nominal length l > 20 000 mm are required, the agreed tolerances on length are to be reported (see 6.3, Table 3);
f) for plates with untrimmed edges, the chosen and agreed measuring points for the measurement of the thickness are to be reported (see 8.2).
4.3 Designation EXAMPLE 20 plates of steel S235JR (1.0038), as specified in EN 10025-2 according to this European Standard with nominal thickness of 25 mm, thickness tolerance class B, nominal width 2 000 mm, nominal length 4 500 mm, with trimmed edges, with limited edge camber and out-of-squareness, with special tolerances for flatness:
5 Form of supply
Plate according to this European standard can be supplied:
with thickness tolerances of class A, 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
6.1.1 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 tolerance of 0,3 mm;
class C: for a fixed minus tolerance of 0,0 mm;
class D: for symmetrical tolerances.
