3 Terms and definitions
No terms and definitions are listed in this document.

4 Chemical composition limits
The chemical composition of aluminium and aluminium alloys is specified in percentage by mass in
Tables 1 to 8. Limits of impurities are expressed as a maximum; limits of alloying elements shown as a
range. Aluminium is specified as a minimum for unalloyed aluminium, and as a remainder for aluminium
alloys.
The chemical composition of internationally registered wrought aluminium and wrought aluminium
alloys not listed in this document can be found in Teal sheet [2].
Analysis shall be made for elements which are specified, for example Pb, Sn, Bi, Sb, Zr.
5 Writing rules
5.1 Standard limits for alloying elements and impurities are expressed in percentage by mass to the
following decimal places:
— less than 0,001 % 0,000X;
— 0,001 % but less than 0,01 % 0,00X;
— 0,01 % but less than 0,10 %:
— unalloyed aluminium made by a refining 0,0XX;
process
— others 0,0X;
— 0,10 % to 0,55 % 0,XX;
— over 0,55 % 0,X; X,X; XX,X.
Exception: combined Si + Fe limits for 1xxx designations shall be expressed as 0,XX or 1,XX.
5.2 The aluminium content for unalloyed aluminium made by a refining process is the difference
between 100,00 % and the sum of all other metallic elements present in amounts of 0,001 0 % or more
each, expressed to the third decimal place before determining the sum, which is rounded to the second
decimal place before subtracting.
For unalloyed aluminium not made by a refining process, the aluminium content is the difference
between 100,00 % and the sum of all other metallic elements present in amounts of 0,010 % or more each
expressed to the second decimal place before determining the sum.
6 Alloy designations
The numerical designation systems used in Teal sheets and European Standards for wrought aluminium
alloys are identical. As specified in EN 573-1 [4] the prefix EN AW- is added.
The alternative chemical symbol based alloy designation system shall be based on EN 573-2.
Both the numerical and the chemical symbol based designations are indicated in Tables 1 to 8.
The International numerical system is the preferred one. The chemical symbol based designations are
indicated for reference only.
To introduce new wrought aluminium and wrought aluminium alloys in standards, Annex B shall be
followed.
7 Sequence of elements
Standard limits for alloying elements and impurities are expressed in the following sequence: silicon, iron,
copper, manganese, magnesium, chromium, nickel, zinc, titanium, gallium, vanadium, remarks, other
elements each, other elements total, aluminium.
Limits of additional specified elements are inserted in alphabetical order of their chemical symbols under
“Remarks”.
8 Rounding rules for determination of compliance
In recording chemical analysis test results, the number representing the result for any element specified
in this document shall be expressed to the same number of decimal places as the corresponding number
in this document. For unalloyed aluminium, the aluminium content is derived as described in 5.2.
The following rounding rules shall be used for determination of compliance with this document:
a) when the figure immediately after the last figure to be retained is less than 5, the last figure to be
retained remains unchanged;
b) when the figure immediately after the last figure to be retained is greater than 5, or equal to 5 and
followed by at least one figure other than 0, the last figure to be retained is increased by 1;
c) when the figure immediately after the last figure to be retained is equal to 5 and followed by zeros
only, the last figure to be retained remains unchanged if even and is increased by 1 if odd.
