1 Scope
This European Standard specifies tolerances on dimensions and shape for continuously hot-rolled uncoated
plate/sheet and strip with a maximum width of 2 200 mm of non-alloy and alloy steels in accordance with
Table 1 (see also Annex A). This European Standard also applies to hot-rolled strip for cold rolling.

This European Standard does not apply to stainless steels and not to hot-rolled strip rolled in widths
< 600 mm [EN 10048].

4 Information to be supplied by the purchaser
4.1 General
The following information shall be supplied by the purchaser at the time of enquiry and order:
a) the quantity to be delivered;
b) designation of the product (wide strip, sheet/plate cut from wide strip, strip slit from wide strip);
c) number of this dimensional standard (EN 10051);
d) nominal thickness and width in mm;
e) the letters GK if strip and sheet/plate with trimmed edges is ordered (see 5.1);
f) nominal length in mm (for sheet and plate);
g) width tolerances for sheet/plate with thickness > 10 mm (see 6.3);
h) tolerances on flatness for sheet/plate of category D (see 6.4.2 and Table 10);
i) flatness requirements for wide strip and strip < 600 mm wide slit from strip (see 7.4);
j) edge camber requirements for strip < 600 mm wide slit from wide strip (see 7.5).
4.2 Options
A number of Options are specified in Annex B. In the event that the purchaser does not indicate his wish to
implement any of these Options, the supplier shall supply in accordance with the basic specification (see 4.1
and 5.1).
4.3 Example
EXAMPLE 1 20 sheets according to this European Standard with nominal thickness of 2,0 mm, nominal width
1 200 mm, with trimmed edges (GK), nominal length 2 500 mm of steel 34Cr4 (1.7033) as specified in EN 10083-3:
20 sheets EN 10051 – 2,0 x 1 200GK x 2 500
steel EN 10083-3 – 34Cr4
EXAMPLE 2 5 t of strip according to this European Standard with nominal thickness of 4,5 mm, nominal width 1 500
mm, with mill edges of steel S235JR (1.0038), as specified in EN 10025-2:
5 t strip EN 10051 – 4,5 x 1 500
steel EN 10025-2 – S235JR
5 Delivery condition
5.1 Sheet/plate and strip shall be supplied with mill edges or with trimmed edges (GK), as agreed at the
time of enquiry and order (see Annex B, Option a).In the absence of information on the form of supply,
sheet/plate and strip shall be supplied with mill edges.
5.2 The possibility of delivering coils with welding seams can be agreed at the time of enquiry and order.
The indication of the location of the weld can be agreed at the same time (see Annex B, Option b).

refer back to the purchaser.
