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text or by endorsement, at the latest by February 2010, and conflicting national standards shall be withdrawn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.

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 pro
