Foreword
This document (EN 487:2009) has been prepared by Technical Committee CEN/TC 132 “Aluminium and
aluminium alloys”, the secretariat of which is held by AFNOR.
This European Standard shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by February 2010, and conflicting national standards shall be withdrawn
at the latest by February 2010.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 487:1993.
Within its programme of work, Technical Committee CEN/TC 132 entrusted CEN/TC 132/WG 2 "Extrusion
billets and rolling ingots" to revise EN 487:1993.
CEN/TC 132 affirms its policy that in the case when a patentee refuses to grant licences on standardised
standard products under reasonable and not discriminatory conditions, then this product shall be removed
from the corresponding standard.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain,
Sweden, Switzerland and the United Kingdom.
1 Scope
This European Standard specifies the general requirements to be met by rolling ingots of aluminium or
aluminium alloys obtained by semi-continuous vertical casting.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN 12258-1:1998 and the following
apply.
3.1
heat
quantity of liquid metal that has simultaneously undergone the same preparatory treatment in the furnace
before the casting operation
4 Ordering information
The ordering information shall define the product required and shall contain the following:
a) the form of the product (rolling ingot);
b) the designation of the aluminium or aluminium alloy according to EN 573-1 and 573-2 (or the purchaser
alloy designation after agreement between supplier and purchaser). Tighter limits than the composition
limits stated in EN 573-3 may be specified as required;
c) whether as cast or homogenized. The homogenizing parameters should be agreed between the supplier
and the purchaser;
d) the number of this European Standard;
e) the dimensions and shape of the product:
1) nominal thickness (expressed in millimetres);
2) nominal width (expressed in millimetres);
3) nominal length and tolerance if different from standard (expressed in millimetres);
4) cross sectional profile details or drawing number (expressed in millimetres);
f) sawing code (see 5.6.4);
g) whether rolling ingots are to be supplied scalped or not;
h) whether the rolling ingots are scalped or not before hot rolling;
i) end use (e.g. foil, packaging) (see 5.1);
j) quantity:
1) mass (in metric tonnes) or number of pieces;
2) quantity tolerances if required;
k) any requirements for inspection documents (see Clause 7);
l) any additional requirements agreed between supplier and purchaser (see Clause 7).
5 Requirements
5.1 Production and manufacturing processes
The product requirements as formulated in this clause normally are not sufficient for rolling ingots to meet the
purchaser's requirements for rolled products. Therefore, the purchaser shall give the manufacturer full details
concerning the end use requirements, so that the manufacturing conditions of the manufacturer may best be
adjusted to fulfil the requirements.
It is recommended that trial quantities be produced to confirm that the end use requirements are met. It is also
recommended that the purchaser asks the manufacturer to advise of any significant change in the
manufacturing processes which may affect the quality of the final product.
It is recommended that a quality assurance system be implemented as described in EN ISO 9000 and
EN ISO 9004.
5.2 Chemical composition
The chemical composition of the ingots shall conform to the compositions specified in EN 573-3.
It is recommended that tighter composition limits than those given in EN 573-3 be agreed between purchaser
and supplier as required.
Control of alkali metals and other specific trace elements is recommended:
a) sodium and calcium for magnesium alloys;
b) lithium for foil end use alloys;
c) beryllium.
The maximum hydrogen content and the related measuring method should be agreed between supplier and
purchaser.
5.3 Surface and internal quality
To be suitable for rolling, after scalping or not as required, and subsequent processing, rolling ingots shall:
a) have low level of casting surface defects, protruding metal, handling marks, oil, dirt and corrosion;
b) have low level of inclusions, porosity, shrinkage cavities and cracks;
c) have a suitable metallurgical structure (e.g. grain size, shell zone depth, fir-tree structure).
The level of quality should be agreed between purchaser and supplier.
5.4 Tolerances on dimensions
5.4.1 Cross-section
The shape of the cross-section is left to the discretion of the purchaser, who shall give the supplier a
dimensional drawing.
5.4.2 Thickness
The thickness is measured on both sides of the ingot at a distance of 100 mm from the edges. The tolerance
on the thickness thus measured is ± 5 mm excluding (see Figure 1):
a) a distance from the bottom butt of the unsawn rolling ingot of 80 % of the nominal thickness (distance
measured before sawing, if any);
NOTE For ingots more than 2 m wide, the distance is equal to the thickness.
b) a distance from the bottom end of the sawn rolling ingot of 50 % of the nominal thickness.
The tolerance on thickness in the zones defined above and measured at the centre of the cross-section is:
c) 4 % of the nominal thickness for sawn ingots;
d) to be agreed between the purchaser and the supplier for unsawn ingots.
Other tolerances and measuring positions can be specified between the supplier and the purchaser.
The difference between the thinnest and the thickest parts of the sawn ingot measured anywhere on the ingot
at a distance greater than 100 mm from the edges shall not exceed 5 % of the nominal thickness.
