EN 1386:2007 (E) 4

Introduction It is essential that aluminium alloy semi-finished rolled products intended for use floor plating, e.g. in vehicle construction, shipbuilding and metallic structures satisfy a certain number of specific technical conditions for inspection and delivery as well as specific mechanical and other properties which distinguish them from similar semi-finished products for general applications.

EN 1386:2007 (E) 5 1 Scope This document specifies the technical conditions of inspection and delivery, the mechanical properties, the tolerances on dimensions and form of rolled semi-finished aluminium alloy products intended for floor plating, e.g. in vehicle construction, shipbuilding and metallic structures with a raised pattern on one side and a smooth surface on the other side. It applies to sheets, strips and plates from 1,2 mm up to 20 mm in thickness and up to and including 2 500 mm in width, and to sheets and plates up to 14 000 mm in length. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

EN 1386:2007 (E) 6 3.3 order document document or set of order documents agreed between supplier and purchaser at the time of order NOTE An order document can be an order of the purchaser confirmed by the supplier or a quotation of the supplier confirmed by the purchaser. 4 Pattern types The most common patterns and their standard designations are shown in Figures 1 to 5 (pattern illustrations are about half actual size).

Figure 4 — Rice grain Figure 5 —Almond 5 Selection of materials Appropriate material of the series 1000 (with a minimum aluminium content of 99,5 %), 3000, 5000, 6000 and 7000 can be used. Their chemical composition shall conform to EN 573-3. The following alloys are recommended for use as floor plating, e.g. in a vehicle construction, shipbuilding and metallic structures: EN AW-1050A, EN AW-3003, EN AW-3103, EN AW-5026, AW-5052, EN AW-5083, EN AW-5086, EN AW-5754, EN AW-6061, EN AW-6082 and EN AW-7020. NOTE For marine application with EN AW-5083 and EN AW-5086 in the H116 temper, 7.6 applies. 6 Order information The relevant requirements of EN 485-1 shall apply, with the following additional provisions: a) the order document shall refer to the present document; b) the order document should specify the type of the inspection document according to EN 10204 (see 8.2); c) the order document shall specify mechanical and other relevant properties, if they differ from those specified in the present standard or if materials other than those recommended in the present document are used; d) the order document should specify the height of the raised pattern (see 7.7.1) and the tolerances on thickness applicable (see 7.7.2). 7 Requirements 7.1 General With special regard to the final use, the supplier and the purchaser shall take into account additional legal regulation and standards and the suitability of the material chosen.

EN 1386:2007 (E) 8 7.2 Technical conditions for inspection and delivery Unless otherwise specified in the present document or in the order document, the relevant requirements of EN 485-1 shall apply. 7.3 Surface conditions The product shall be free from defects prejudicial to its suitable and proper use. Whilst an operation designed to mask a fault is not permitted, the elimination of a superficial fault is permissible, provided that the dimensional tolerances and material properties continue to meet the specifications. NOTE Reverse side can show ripples, due to partial penetration of pattern during levelling. 7.4 Mechanical properties For alloys given in Clause 5, the mechanical properties at ambient temperature shall conform to Table 1. Higher mechanical properties can be agreed upon between supplier and purchaser. The mechanical properties at ambient temperature shall be measured according to EN 10002-1.
