25 t 20 000 m shall be agreed at
het time of enquiry and order.
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 a rectangle with the dimensions of the
ordered plate within the delivered size.
For plate specified with limited edge camber and out-of squareness in the order, the maximum values
for edge camber and out-of squareness shall be agreed at the time of the enquiry and order
Tolerances on witdh for plates with trimmed
edges are given in Table 2 depending on the

Tolerances on widht for plates with
untrimmed edges (NK) shall be the subject of
agreement between the manufacturer and
purhcaser at the time of enquiry and order.
Tolerances
These thickness tolerances apply outside ground areas *
At the time of the enquiry and order the purchaser shall indicate if a class A, B, C or D tolerance
is required. If no class is stated, class A applies.
* For permissible limits concerning surface imperfections and requirements for repair EN
10163-1 and EN 10163-2 apply.
Thickness
Tolerances on thickness are given in Table 1. Plates may be supplied with either
- class A: for minus thicknees tolerances depending on the nominal thickness;
- class B: for a fixed minus tolerance of 0.3 mm;
Table 1 - tolerances on thickness
- class C: for a fixed minus tolerance of 0.0 mm;
- class D: for symmetrical tolerances.
