EN 1396:2015 (E) 4 Foreword This document (EN 1396:2015) 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of an identical text or by endorsement, at the latest by October 2015 and conflicting national standards shall be withdrawn at the latest by October 2015. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1396:2007. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

EN 1396:2015 (E) 5 Introduction Organic coated aluminium and aluminium alloy strip and sheet products can be used to advantage in cases where corrosion 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 packaging 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. As a general rule, material specifications shall be agreed between manufacturer and user/purchaser using, when appropriate, the guidelines from Annex C. Guidelines for proper storage and subsequent processing of organic coated aluminium flat products are given in Annex D. SIST EN 1396:2015



EN 1396:2015 (E) 6 1 Scope This European Standard specifies the particular requirements for wrought aluminium and wrought aluminium alloys in the form of coil coated sheet and strip for general applications. This product is generally supplied in thicknesses up to 3,0 mm. It applies to cold-rolled aluminium and aluminium alloy strip coated by the coil coating process both with liquid as well as with powder paints, either in the final width or slit afterwards, and to sheet obtained from such strip. It does not apply to coil coated sheet and strip used for special applications such as cans, closures and lids which are dealt with in separate EN 541. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

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 uniform appearance, colour and texture and be essentially free of blemishes such as flow lines, streaks, blisters or other imperfections. 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. Uniformity and aesthetic faults shall be noted when visible. Visible examination shall be done at following distances: — Building façade applications: 5 m for external and 3 m for internal use; — All other applications: 3 m for external and 2 m for internal use. 4.2.4 Chemical composition The chemical composition shall comply with the requirements as specified in EN 573-3. 4.2.5 Mechanical properties The mechanical properties shall be in conformity with those specified in Clause 5 or those agreed upon between 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 thicknesses see 6.1. Unless otherwise agreed, the purchaser may reject only those products having dimensions not complying with the specified tolerances. SIST EN 1396:2015



EN 1396:2015 (E) 12 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 ISO 6892-1:2009, and the following additional requirements: — the test-piece shall be taken with its length transverse to the rolling direction. For narrow widths (less than 300 mm) testing in the rolling direction is permitted. In this case, testing direction shall be reported and specified; — 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; — 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 accordance with the following standards: — coating thickness (when required): EN 13523-1; — specular gloss: EN 13523-2; — colour difference: EN 13523-3 and EN 13523-22. NOTE Instrumental comparison for colour difference (EN 13523-3) does not give reliable values in the case of embossed or textured coatings, metallic or pearlescent pigmented coatings. The frequency of testing shall be as for the tensile test. Other tests may be specified. The methods of testing, if other than the ones in the normative references (see paragraph 2), 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. SIST EN 1396:2015
