EN 1396:2007 (E) 4 Introduction Organic coated aluminium and aluminium alloy flat products can be used to advantage in cases where corro-sion resistance and decorative appearance are of primary importance. They have applications throughout the flat products processing industry e.g. in the building, automotive, caravans, appliances, fabricating and pack-aging industries. Organic coated aluminium and aluminium alloy flat products can be delivered in numerous types and grades, depending on the base material used (various grades of aluminium), on the coating material and types of coating and on the requirements for the surface appearance and the formability. The properties of the products can vary within greater or smaller limits depending on the choice and
combination of properties required. It is therefore not practicable to specify in detail minimum requirements for all properties for all types of products. Minimum requirements not specified in this European Standard and deemed necessary for a successful use of the product should be agreed between manufacturer and purchaser at the time of ordering, using, as
appropriate, the guidelines given in Annex C. Guidelines for proper storage and subsequent processing of organic coated aluminium flat products are given in Annex D.

4.2 Requirements 4.2.1 Production and manufacturing processes Unless otherwise specified in the order, the production and manufacturing processes shall be left to the dis-cretion of the manufacturer. Unless it is explicitly stated in the order no obligation shall be placed on the manufacturer to use the same processes for subsequent and similar orders. 4.2.2 Quality control The manufacturer 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 manufacturer at the time of placing the order. 4.2.3 Freedom from defects The product shall be free from defects prejudicial to its suitable and proper use. Its surface shall be of a uni-form appearance, colour and texture and be essentially free of blemishes such as flow lines, streaks, blisters or other imperfections.



EN 1396:2007 (E) 11 Tolerance on surface defects is normally greater for products supplied as coils (as compared to sheets) due to the impossibility of removing defects within coils and this should be taken into account by the purchaser when assessing the product. Limiting samples may be agreed. 4.2.4 Chemical composition The chemical composition shall comply with the requirements as specified in EN 573-3 and for alloys EN AW-5006 and EN AW-6025 as specified in Annex E. 4.2.5 Mechanical properties The mechanical properties shall be in conformity with those specified in Clause 5 or those agreed upon be-tween the supplier and the purchaser and stated on the order. 4.2.6 Tolerances on shape and dimensions The tolerances on shape and dimensions specified in EN 485-4 shall apply. NOTE Tolerances on thickness only apply to the uncoated (bare) metal substrate. For the tolerances on the organic coating thickness see 6.1. Unless otherwise agreed, the purchaser may reject only those products having dimensions not complying with the specified tolerances. 4.2.7 Coating properties Property requirements relating to the organic coating are specified in Clause 6. Other requirements shall be agreed by the supplier and the purchaser and stated on the order. Annex C gives some guidelines for such requirements. 4.3 Test procedures 4.3.1 Chemical composition For chemical composition testing see EN 485-1. 4.3.2 Tensile test For the selection and preparation of samples and test-pieces see EN 485-1. Testing shall be carried out according to EN 10002-1, and the following additional requirements:  the test-piece shall be taken with its length transverse to the principal direction of rolling, whenever possible. For narrow widths (less than 300 mm) testing in the longitudinal direction is permitted;  the test-piece shall have a reduced section 12,5 mm wide;  unless otherwise agreed testing shall be carried out on the coated material. The thickness of the metal substrate shall be used for the calculation of the cross-section;  the elongation shall be measured using an original gauge length of 50 mm. Testing shall be carried out on at least one test-piece taken from each inspection lot. Furthermore testing shall be carried out on:  one test piece taken from each master coil of more than 1 000 kg;



EN 1396:2007 (E) 12  one test piece taken from every 10 master coils of 500 kg up to 1 000 kg;  one test piece taken from every 25 master coils of less than 500 kg. 4.3.3 Coating tests The coating tests shall be carried out either as agreed upon by the manufacturer and the purchaser or in ac-cordance with the following standards:  coating thickness (when required): EN 13523-1;  specular gloss: EN 13523-2;  visual colour difference: EN 13523-22. The frequency of testing shall be as for the tensile test. Other tests can be specified. The methods of testing, the acceptance criteria and the frequency of testing shall be agreed between supplier and purchaser. Guidelines for such specification are set out in Annex C. 4.3.4 Retests Retests shall be carried out in conformance with EN 485-1. 5 Mechanical properties Properties shall be in conformance with those specified in Table 2, using the rounding rules set out in Annex A. Properties for alloys and/or tempers not covered in Table 2 shall be agreed between manufacturer and pur-chaser.

6 Organic coating properties 6.1 Tolerances on thickness When specified in the order document, the thickness of the organic coating shall meet the tolerances given in Table 3. These tolerances on the specified coating thickness shall apply to the total organic coating thickness on each relevant side, but not including the adhesive film thickness (where applicable).



EN 1396:2007 (E) 15 The measurements shall be carried out on a representative specimen. Three measurements shall be made. Table 3 — Tolerances on total thickness of the organic coating
Dimensions in micrometres Specified thickness range 3 to 5 over 5 to 10 over 10 to 20 over 20 to 25 over 25 to 35 over 35 to 60 over 60 to 100 over 100 to 200 morethan200 Maximum allowable deviation (minus tolerance) from the specified thickness: for an average of three measure-ments 2 2 2 3 3 5 10 15 20 Maximum allowable deviation (minus tolerance) from the specified thickness: for an individual measurement 2 3 4 5 6 8 15 25 40 NOTE 1 Other tolerances can be agreed between manufacturer and purchaser as well as the measuring method to be used, in particular for structured coatings such as polyamide modified coatings. NOTE 2 There are no requirements for backing coat. NOTE 3 There are no requirements for the plus tolerance.
6.2 Tolerances on gloss The tolerances on gloss are specified in Table 4. These tolerances apply to measurements carried out in accordance with EN 13523-2 using a 60° head, unless otherwise agreed. For gloss values below 13, an 85° head should be used. Table 4 — Tolerances on gloss
Values in gloss units Gloss unit range Tolerances on nominal gloss Maximum variation within one supply Gloss type ≤ 5 ± 2 ± 1 matt
6 to 12 13 to 20 ± 3 ± 4 ± 2 ± 2 low gloss 21 to 30 31 to 40 41 to 60 ± 5 ± 6 ± 7 ± 3 ± 3 ± 5 semi-gloss 61 to 79 ± 8 ± 7 gloss ≥ 80 minimum 80 full gloss NOTE 1 Other values can be agreed between supplier and purchaser. NOTE 2 Specular gloss readings do not apply to textured finishes.



EN 1396:2007 (E) 16 6.3 Tolerances on colour The colour shall match visually the colour specified. If necessary, appropriate colour tolerances should be agreed in advance (see Annex C). 7 Inspection documents Inspection documents shall be issued in accordance with EN 485-1. 8 Marking Unless otherwise agreed at the time of ordering, the following minimum marking requirements shall apply:  name or mark of the manufacturer;  alloy and temper designation for the substrate;  information on the coating on each surface;  order number;  ordered dimensions;  production batch number and mass. Each of this items shall be given on a label, which is to be attached to every coil or pack. 9 Packing The packing requirements shall be agreed between manufacturer and purchaser at the time of ordering.
