Aluminium and aluminium alloys - Extruded round, coiled tube for general applications - Specification
This standard specifies the technical conditions for inspection and delivery, mechanical properties and tolerances on dimensions and form for aluminium and aluminium alloy extruded round, coiled tubes for general applications with outside or inside diameters in the range from 5 mm up to and including 30 mm.
Depending on the final application of the product, additional or stricter requirements may apply, after agreement between supplier and purchaser.
NOTE Some of the products listed in the present standard can be subject to patent or patent applications, and their listing herein is not be construed in any way as 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.

This European Standard mainly applies to round extruded tube for general engineering applications manufactured in 1xxx series of aluminium and 3xxx series of alloys. The use of this European Standard for non-standardised 1xxx aluminium and 3xxx alloys or alloys from other series, e.g. 5xxx or 6xxx, is subject to agreement between supplier and purchaser. This European Standard only applies to:
round tube produced by the porthole/bridge method, extruded in coil form to the final dimensions required; tube as above but delivered in straight lengths cut from coiled material. This European Standard does not apply to: seamless extruded (die/mandrel method) tubes (EN 755-7); tubes extruded in straight lengths (i.e. not coiled) (EN 755-8). 2 Normative references The following referenced documents are indispensable for the application of this document.

If the purchaser wishes to inspect the product at the manufacturer's works, he shall notify the supplier at the time of placing the order. 5.3 Chemical composition limits The chemical composition limits shall be in conformity with the requirements specified in EN 573-3. If the purchaser requires closer limits for elements than those specified in EN 573-3, these limits shall be according to an agreement between supplier and purchaser and stated in the order document. 5.4 Mechanical properties The mechanical properties shall be in conformity with those specified in EN 755-2 or those agreed between supplier and purchaser and stated in the order document. Typical Brinell hardness (mainly used for flat surfaces, i.e. basically not suitable for round tubes/non-flat surfaces) values are given in EN 755-2, but they are not binding for acceptance purposes. However, a Brinell hardness value may be agreed upon for acceptance testing. 5.5 Surface quality 5.5.1 Surface quality in general The surface shall be free from defects prejudicial to its suitable and proper use. The reference standard shall be agreed between supplier and purchaser. The product shall have a smooth and clean surface. However, small surface defects such as light scratches, indentations, discolouration and non-uniform surface appearance resulting from the manufacturing process (which cannot always be totally avoided) are generally permitted. Such surface quality is commonly referred to as “normal quality”.
A greater degree of tolerance of surface defects (in respect to both the number and severity) is normally necessary for tube supplied in coil form compared to straight lengths, since it is not possible to remove individual defects within the coil. This issue should be taken into account by the purchaser when placing an order for coiled tube. SIST EN 13957:2009

5 Requirements
5.1 Production and manufacturing processes
Unless otherwise specified in the order document, the production and manufacturing processes shall be left to
the discretion of the manufacturer. Unless it is explicitly stated in the order document, no obligation shall be
placed on the manufacturer to use the same processes for subsequent similar orders.
5.2 Quality control
The supplier shall be responsible for the performance of all inspection and tests required by the relevant
European Standard and/or the particular specification prior to shipment of the product. If the purchaser wishes
to inspect the product at the manufacturer's works, he shall notify the supplier at the time of placing the order.
5.3 Chemical composition
The chemical composition shall be in conformity with the requirements specified in EN 573-3.
If the purchaser requires closer limits for elements other than those specified in EN 573-3, these special limits
shall be stated in the order document (after agreement between supplier and purchaser).
5.4 Mechanical properties
The mechanical properties shall be in conformity with those specified in prEN 755-2 or those agreed between
supplier and purchaser and stated in the order document.

---------------------- Page: 7 ----------------------
prEN 13957:2007 (E)
Typical Brinell hardness (mainly used for flat surfaces, i.e. basically not suitable for round tubes/non-flat
surfaces) values are given in prEN 755-2, but they are not binding for acceptance purposes.
5.5 Surface quality
5.5.1 Surface quality in general
The surface shall be free from defects prejudicial to its suitable and proper use. The reference standards shall
be agreed between supplier and purchaser.
The product shall have a smooth and clean surface. However, small surface defects such as light scratches,
indentations, discolouration and non-uniform surface appearance resulting from the manufacturing process
(which cannot always be totally avoided) are generally permitted on the product surface. Such surface quality
is commonly referred to as “normal quality”.
A greater degree of tolerance of surface defects (in respect to both the number and severity) is normally
necessary for tube supplied in coil form compared to straight lengths, since it is not possible to remove
individual defects within the coil. This issue should be taken into account by the purchaser when placing an
order for coiled tube.
5.5.2 Surface defects and detection
In the case of stricter and more specific requirements than “normal quality”, the following shall be subject to
agreement between supplier and purchaser:
the testing/detection method (e.g. eddy current testing, pressure/leak testing etc.);
the type (scratches, dents etc.) and size of defects;
the method of marking the defects (e.
