Foreword
This document (EN 546-4:2006) 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text or by endorsement, at the latest by June 2007, and conflicting national standards shall be withdrawn at
the latest by June 2007.
This document supersedes EN 546-4:1997.
Within its programme of work, Technical Committee CEN/TC 132 entrusted CEN/TC 132/WG 6 "Foil and
finstock" to revise EN 546-4:1997.
The following modifications have been made:
 Clause 3: reference to EN 12258-1:1998 has been added, the definition of perforation has been deleted;
 Clause 4: Table 1: limitation of pinholes (6 µm to 20 µm) detection range for light gauge converter double
roller (6 µm to 70 µm) has been deleted;
 Clause 6: addition of test by use of Cotton Wool Pad (6.3.4);
 Figure 3 second Figure has been added.
EN 546 comprises the following parts under the general title "Aluminium and aluminium alloys - Foil":
 Part 1: Technical conditions for inspection and delivery
 Part 2: Mechanical properties
 Part 3: Tolerances on dimensions
 Part 4: Special property requirements
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN shall not be held responsible for identifying any or all such patent rights.
CEN/TC 132 affirms it is its policy that in the case when a patentee refuses to grant licenses 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, 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 United Kingdom.
1 Scope
This document specifies the requirements for special properties of wrought aluminium and wrought aluminium
alloy foil and their tests. It applies to flat rolled products.
It does not apply to lacquered, painted, embossed or laminated products.
The technical conditions for inspection and delivery of foil are specified in EN 546-1.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
EN 12258-1:1998, Aluminium and aluminium alloys — Terms and definitions — Part 1: General terms
