Foreword
This European Standard 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by endorsement, at the latest by October 2001, and conflicting national standards shall be withdrawn at the latest
by October 2001.
Within its programme of work, Technical Committee CEN/TC 132 entrusted CEN/TC 132/WG 5 "Extruded and
drawn products" to prepare the following standard :
EN 755-9, Aluminium and aluminium alloys- Extruded rod/bar, tube and profiles - Part 9 : Profiles, tolerances on
dimensions and form.
This standard is part of a set of nine standards. The other standards deal with :

1 Scope
This part of EN 755 specifies the tolerances on dimensions and form for aluminium and aluminium alloy extruded
profile with a cross section contained within a circumscribing circle not greater than 800 mm (see Figure 1).
This standard applies to extruded profiles for general engineering applications only.
The tolerances in this standard only apply to those dimensions that can be physically measured.
NOTE Some of the products listed in the present standard can be subject to patent or patent applications, and their listing
herein does not in any way imply the granting of a licence under such patent right.
CEN/TC 132 affirms it is 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.

2 Alloy groups
For the purpose of this European Standard, the alloys are distributed into two groups which correspond to varying
degrees of difficulty when manufacturing the products.
The division into group I and group II of the most commonly used general engineering alloys is specified in table 1.
Grouping of other alloys is subject to agreement between purchaser and supplier.

3 Tolerances on dimensions
3.1 Cross-sectional dimensions
3.1.1 General
The tolerances on the dimensions listed below (see Figure 2) are specified in the relevant Tables 2 to 8.
A : wall thicknesses except those enclosing the hollow spaces in hollow profiles ;
B : wall thicknesses enclosing the hollow spaces in hollow profiles except those between two hollow spaces ;
C : wall thicknesses between two hollow spaces in hollow profiles ;
E : the length of the shorter leg of profiles with open ends ;
H : all dimensions except wall thickness.

3.1.2 Tolerances on dimensions other than wall thickness
The tolerances on dimensions shall be as specified in Tables 2 and 3. For profiles with open ends (see Figures 3, 4
and the relevant examples) the tolerances specified in Table 4 shall be added to those of Tables 2 and 3 for
dimension H across open ended legs in order to obtain the tolerances on the gap between any opposite points on
these ends.
