EN 13480-8:2012 (E) Issue 1 (2012-06) 5 Foreword This document (EN 13480-8:2012) has been prepared by Technical Committee CEN/TC 267 “Industrial piping and pipelines”, 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of an identical text or by endorsement, at the latest by December 2012, and conflicting national standards shall be withdrawn at the latest by December 2012. 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 has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. This European Standard EN 13480 for metallic industrial piping consists of eight interdependent and not dissociable Parts which are: Part 1: General; Part 2: Materials; Part 3: Design and calculation; Part 4: Fabrication and installation; Part 5: Inspection and testing; Part 6: Additional requirements for buried piping; CEN/TR 13480-7, Guidance on the use of conformity assessment procedures; Part 8: Additional requirements for aluminium and aluminium alloy piping. Although these Parts may be obtained separately, it should be recognised that the Parts are inter-dependant. As such the manufacture of metallic industrial piping requires the application of all the relevant Parts in order for the requirements of the Standard to be satisfactorily fulfilled. This European Standard will be maintained by a Maintenance MHD working group whose scope of working is limited to corrections and interpretations related to EN 13480.
The contact to submit queries can be found at http://portailgroupe.afnor.fr/public_espacenormalisation/CENTC267WG8/index.htm. A form for submitting questions can be downloaded from the link to the MHD website. After subject experts have agreed an answer, the answer will be communicated to the questioner. Corrected pages will be given specific issue number and issued by CEN according to CEN Rules. Interpretation sheets will be posted on the website of the MHD.

Aluminium and aluminium alloys used for parts of industrial piping that are not subjected to cold forming (e.g. straight flanges and nozzles) shall have a specified minimum elongation after fracture measured on a gauge length

EN 13480-8:2012 (E) Issue 1 (2012-06) 11 5.4 Chemical composition The chemical composition shall be in accordance with the material specification. All materials shall have a maximum lead content of 150 µg/g. NOTE 5.1.3 of EN 12392:2000 recommends a maximum hydrogen level of 0,2 ml per 100 g aluminium, measured in the liquid metal during casting for parts to be welded. 5.5 Lamellar tearing Specific requirements to avoid lamellar tearing for industrial piping of aluminium and aluminium alloys are not applicable. NOTE Specific requirements apply to steel (see EN 1011-2:2001) whereas in EN 1011-4:2000 no requirement is given because lamellar tearing is not a recognized phenomenon.
5.6 Design temperature and properties NOTE See also 4.2.2 of EN 13480-2:2012.
The 2nd paragraph of 4.2.2.1 of EN 13480-2:2012 is not applicable for aluminium and aluminium alloys.
The maximum design temperature shall not exceed that defined in Table 1 of EN 12392:2000 as the maximum working temperature. For material of group 22.4 the maximum design temperature is 75 °C
(200 °C for non-corrosive service). The mechanical properties used for design shall be taken from the tabulated values in EN 12392:2000 at room temperature for Rm/20 / Re/20 and at the highest design temperature for Re/t.
For welded parts and heat treated parts after forming only the values equivalent to the O temper shall be used for design when 6 000 series flanges, etc. are welded. These values are not quoted in EN 12392:2000 and so the tabulated values for f shown in Table 6.2-2 shall be used for design. The weld area shall be based on the O temper but the flange strength away from the weld (2t) may be based on the actual temper (T4 or T6). For aluminium and aluminium alloys values of 0,2 % proof stress (or 1 % proof stress for material group 21-1 000 series aluminium) for temperatures above 20 °C shall be established by linear interpolation between two adjacent va
