3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
circle
circular flat product obtained by circular sawing or shearing, or by blanking of a fiat rolled product with a uniform thickness over 0,20 mm
3.2
circle stock
flat rolled product of rectangular cross-section with uniform thickness over 0.20 mm. supplied in coils, sheets, or plates, usually with sheared or sawn edges. and intended to be sawn, sheared or blanked into flat shapes to be subsequently formed, drawn, etc.
Note 1 to entry: The thickness does not exceed one tenth of the width

4 Technical conditions for inspection and delivery
4.1 General
All the provisions of EN 485-1 shall apply, except Clause 4 (orders and tenders) which is modified as follows:
4.2 Orders or tenders
The order or tender shall define the product required and shall contain the following information:
a) the form and the type of product:
1) the form of the product (circle and circle stock):
2) the designation of the aluminium or aluminium alloy:
3) when subsequent decorative anodising, anti-adhesive coating, enamelling, etc. by the customer is intended, this shall be expressly stated on the order. In all other cases, indication of the customer application is recommended;
b) the metallurgical temper of the material for delivery according to EN 515 (degree of hardness or heat treatment condition) and, if different, the metallurgical temper for use:
C) the number of this European Standard or Specification number, or where none exists, the properties greed between purchaser and supplier;
d) the dimensions and shape of the product as applicable:
1) thickness;
2) diameter of the circle;
3) width of the strip, sheet, or plate:
4) length of the sheet or plate;
5) internal and external diameters of the coil; e) whether hot rolled or cold rolled tolerances apply;
f) quantity:
1) mass or number of pieces:
2) tolerances on quantity if required:
g) any requirements for inspection documents:
h) any special requirements agreed between purchaser and supplier:
1) marking of products;
2) references to drawings, etc:
3) any special test required (earing. etc.) and the corresponding acceptation limits:
i) for products intended to be surface treated by the purchaser the order shall also contain the fo’lowing information:
1) the intended particular surface treatment (according to the relevant European Standard)
2) the number of sides for which a good visual appearance is required and, if only one side, Its position with respect to the strip (inside or outside of the coil) or the sheet, plate or circle (upside or downside).
5 MechanIcal properties
5.1 General
The mechanical properties shall conform to the requirements specified in EN 485-2.
5.2 Earing
When applications, such as deep drawing and spinning require a limited level of earing, the maximum acceptable level shall be agreed between purchaser and supplier. recognising that test results may be dependent on testing procedures.
6 Tolerances on dimensions and form
6.1 General
Tolerances on dimensions and form shall conform to EN 485-3 and EN 485-4, with the amendments and
additions given in 6.2 to 6.5.
6.2 Diameter
Tolerances on diameters for circle shall conform to Table 1. These tolerances include the tolerances on roundness.
NOTE For cirde obtained by blanking, the recommended standard diameters are:
— From 100 mm up to 500 mm nominal diameter: every multiple of 5;EN 851-2014 pdf download.
