DIN EN 14286:2008-11 EN 14286:2008 (E) 4 Introduction It is essential that aluminium alloy semi-finished rolled products intended for the construction of tanks for the storage and transportation of dangerou
22、s goods 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.

23、ies 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 tanks for the storage and transportation of dangerous goods, in particular of gasoline and other liquid hydrocarbons
24、. It applies to hot or cold-rolled strip, sheet and plate with a thickness from 3,0 mm and up to and including 12,0 mm used as a wall material. NOTE Compliance with the present document does not ensure compliance with national or international regulations. The user of the document is responsible for
25、 checking that the material he orders or sells complies with all applicable regulations. Depending on the chemical and physical properties of the dangerous good to be transported or stored, it can be necessary to agree on additional properties or inspection conditions in order to comply with applyin

32、he following apply. 3.1 capability clause clause whose reference signifies that sufficient evidence of a statistical nature with respect to the properties under consideration can be submitted by the manufacturer to demonstrate that the requirements of the relevant material standard or specification
33、can be met on the basis of a reduced amount of testing 4 Selection of materials Appropriate material of the series 1xxx (with a minimum aluminium content of 99,5 %), 2xxx, 5xxx and 6xxx can be used. Their chemical composition shall conform to EN 573-3. NOTE Weldability and corrosion resistance of 2x
34、xx series alloys are globally inferior compared to 1xxx, 5xxx and 6xxx series alloys. This aspect should be taken into account when selecting appropriate material. The following alloys are recommended for tanks for the storage and transportation of gasoline and other liquid hydrocarbons: EN AW-5059,
35、 EN AW-5083, EN AW-5086, EN AW-5088, EN AW-5182, EN AW-5186, EN AW-5383, EN AW-5454, EN AW-5754. Although the supplier of the material is not responsible for the final use and application, it is helpful to indicate the final use of the product, and especially the type of dangerous goods which will b
36、e in contact with the material (such as gasoline, other hydrocarbon liquids, halogenated hydrocarbon liquids, phenols, alcohols, ketones, sodium perchlorate etc.). 5 Designation of the products The designation of the aluminium alloys shall conform to EN 573-3. The designation of the tempers shall co
37、nform to EN 515. 6 Ordering 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)
38、 the order document should specify the tolerances on thickness applicable (see 7.5); d) the order document shall specify mechanical and other relevant properties, if they differ from those specified in the present document or if materials other than those recommended in the present document are used

DIN EN 14286:2008-11 EN 14286:2008 (E) 7 7 Requirements 7.1 General For determination of the final use, the manufacturer of the tank shall take into account additional legal regulation and the suitability of the material chosen. 7.2 Technical conditions for inspection and delivery Unless otherwise
40、 specified in the present document or in the order, the relevant requirements of EN 485-1 shall apply. 7.3 Mechanical properties For all aluminium and aluminium alloys, the following requirements shall be fulfilled: a) the elongation after fracture (in %) shall not be less than the greater of the fo
41、llowing two values: 10 000 / 6 Rm(where Rmis expressed in MPa), or 12 %. NOTE 1 Materials listed in Table 1 always fulfil this requirement; b) the minimum guaranteed 0,2 % proof strength Rp0,2shall not be greater than 0,85 times the minimum tensile strength Rm. NOTE 2 Materials listed in Table 1 alw
42、ays fulfil this requirement; c) the minimum bending radius at 180, measured according to EN ISO 7438, shall be smaller than 5 times the thickness if Rm 98 MPa, or smaller than 6 times the thickness if Rm 98 MPa; d) for thickness from 6 mm to 12 mm, the bending radius at 90 shall be measured accordin
43、g to EN 485-1. Unless otherwise specified by the purchaser, the “capability clause“ shall apply for bending radius. For the materials recommended in Clause 4, the mechanical properties at ambient temperature shall conform to Table 1. Higher mechanical properties can be agreed upon between supplier a
44、nd purchaser. NOTE 3 The mechanical properties specified in Table 1 allow the determination of the minimum wall thickness of the tank on the basis of the equivalence formula specified in the A.D.R. regulation. The mechanical properties at ambient temperature shall be measured according to EN 10002-1
45、, using proportional test pieces, and taking into account the particular requirements of the A.D.R. 3. The elongation after fracture A shall be measured, in accordance with this Regulation, in the following manner: For rolled products, the axis of the tensile test pieces shall be perpendicular to th
46、e rolling direction. The elongation after fracture A shall be measured by means of round-section test pieces, the gauge length Loof which shall be equal to five times the diameter d. In the case of test pieces with rectangular cross-section, the gauge length shall be calculated by the formula: ooSL
47、5,65= where Sois the initial section of the test piece.
