Aluminium and aluminium alloys - Wrought products and cast products - Special requirements for products intended for the production of pressure equipment
This European Standard specifies the material requirements and testing procedures applicable to wrought and cast aluminium and aluminium alloys intended for use in the production of pressure equipment, according to the definition given in European Pressure Equipment Directive 97/23/EC.
The standard covers:
- the products forms, grades and tempers of wrought and cast aluminium and aluminium alloys which may be used for such applications together with data for wrought and cast alloys over their permissible working temperature ranges;
- the permissible alloys/ tempers covered by this are those given in Table A.1 and in B.1 for wrought alloys and in Table A.2 and in B.2 for castings;
- the technical conditions for inspection and delivery, mechanical property limits and tolerances on form and dimensions by reference to the appropriate European standards for the relevant wrought and cast aluminium and aluminium alloys, and
- additional requirements which are specific to pressure equipment applications.
It applies to hot-rolled plate, cold-rolled sheet/ strip/ circles, extruded or extruded and cold drawn rod/bar, tube, extruded open / hollow profiles, forgings and castings.
It is the sole objective of this standard to cover materials only for pressure purposes and it excludes any elements of fabrication or fabrication methods for pressure equipment; such information can be found in the relevant standards listed in the 'Bibliography' section.

The range of applications extends from relatively low pressure automotive equipment such as heat exchangers to heavy duty applications including unfired pressure vessels and piping used in pressure equipment. As a result, it will be necessary for the standard to detail an extensive range of aluminium product forms, alloys and tempers as follows: — sheet, strip, plate and circles (EN 485, EN 941); — cold drawn rod/bar and tube (EN 754); — extruded rod/bar, tube and profiles (EN 755); — precision profiles (EN 12020); — extruded coiled tube (EN 13957); — cold drawn coiled tube (EN 13958); — forgings (EN 586); — castings (EN 1706).

NOTE For heat exchangers, for use in equipment not subject to the requirements of the EU directive listed in Annex ZA, other materials can be used after written agreement between supplier and purchaser. If the pressure equipment is operating above room temperature for times exceeding 100 h, then the long time behaviour of the material according to Tables B.1 to B.4 shall be considered. 4.2 Wrought products Applicable alloys and the chemical compositions for wrought alloys are given in Table 2. The chemical compositions of aluminium and aluminium alloys are specified in percentage by mass. Limits for impurities are expressed as maxima that also will apply to alloying elements unless expressed as a range. Aluminium is specified as a minimum for unalloyed aluminium, and as a remainder for aluminium alloys. 4.3 Cast products Applicable alloys and the chemical compositions for cast alloys are given in Table 3. The chemical compositions of aluminium and aluminium alloys are specified in percentage by mass. Limits for impurities are expressed as maxima which also will apply to alloying elements unless expressed as a range. 5 Technical conditions for inspection and delivery 5.1 Manufacturing methods 5.1.1 General The provisions of EN 485-1 (sheets, strips and plates), EN 941 (circles), EN 755-1 (extruded rods/bars, tubes and profiles), EN 754-1 (cold drawn rods/bars, and tubes), EN 12020-1, EN 13957, EN 13958, EN 586-1 (forgings incl. seamless rolled rings), EN 1559-1 (Founding) and EN 1559-4 (Founding) apply with the amendments and additions specified in 5.2 to 5.5 below. Unless otherwise agreed between supplier and purchaser, the manufacturing methods used shall be left to the discretion of the supplier. In addition, there shall be no obligation on the supplier to use the same processes or process route for subsequent or similar orders. 5.1.2 Specific requirements regarding porthole extruded and/or drawn products Regarding porthole extruded and/or drawn products, limitations for safe application of porthole extruded and/or drawn products are provided at Tables 4 and 5: — Table 4 applies to porthole extruded tube (EN 755-8), porthole extruded and drawn tube (EN 754-8), porthole extruded hollow profiles (EN 755-9) and porthole extruded precision profiles (EN 12020) and may be used up to and including an outside diameter of 600 mm (DN 600) and a thickness (t) of maximum 20 mm — Table 5 applies to porthole extruded coiled tube (EN 13957) and porthole extruded and drawn coiled tube EN 13958 and may be used up to and including an outside diameter 50 mm (DN 50) and a thickness (t) of maximum 5 mm. The stated values for allowable maximum pressure (PS) and volume (V) in Tables 4 and 5 are limitations superseding those disclosed in (PED) 97/23/EC . SIST EN 12392:2016
EN 12392:2016 (E) 12 The purchaser and or equipment manufacturer (when different) is responsible for the design of the final equipment. As a result, the purchaser and/ or equipment manufacturer (if different) shall, when placing an order with the supplier (material manufacturer), provide the following information to ensure that the correct Hazard Category and adequate quality assurance is applied to the particular combination of criteria: — the type of pressure equipment being considered (vessel or piping acc. to 97/23/EC Art. 1 and intended use); — the state of the fluid in the equipment (gas or liquid); — the hazard group of the fluid (acc. to PED 97/23/EC Art. 9); — design maximum pressure (PS); — confirmation that the completed equipment assembly will be pressure tested. The supplier (material manufacturer) shall not be liable for any issues arising from inaccurate information provided by the purchaser/equipment manufacturer. NOTE 1
Some further comment is necessary on the methods of extrusion used for tube and hollow profiles. In particular seamless extrusion produces a product that does not contain any seams or weld lines in the product cross-section. On the other hand extruded products manufactured using a porthole or bridge die will contain at least one longitudinal weld or seam. The presence of such welds or seams can be a major concern on products that are to be used for e.g. pressure vessels since the weld/seam could lead to premature failure of the vessel under pressure. NOTE 2 In addition despite rigorous process control during the extrusion process, there is no definitive non-destructive test method that can provide total assurance of the integrity of the welds in the product cross-section. In view of the safety implications of using porthole products, it is necessary to provide guidelines in this standard as to the permitted product areas where porthole products may or may not be used. NOTE 3 It needs to be highlighted that, beside the limits for nominal size DN and thickness t, Tables 4 and 5 provide additional limitations regarding pressure PS, volume V and testing procedures. The equipment supplier can decide to use porthole extrusion for products exceeding the stated limits/hazard categories, but this can only be done after written agreement between supplier and purchaser, and provided that adequate quality assurance/testing procedures are agreed. 5.1.3 Quality control The manufacturer/supplier 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 carry out an inspection prior to shipment, this shall be agreed with the supplier and the request shall be stated on the original order. 5.2 Orders or tenders The order or tender documents shall define the product required and co
