This document specifies tolerances on dimensions and form of extruded precision profiles in alloys EN AW-6060 and EN AW-6063, manufactured with and without a thermal barrier (see Figures 1 and 2). It applies to extruded products supplied without further surface treatment. Precision profiles covered in this document are distinguished from extruded profiles for general applications covered in EN 755-9 by the following characteristics:- they are mainly for architectural applications designed with mostly uniformly wall-thicknesses;- they are mainly used for architecture, mechanical engineering and automotive applications (except structural-parts and crash-elements); - the maximum weight per metre of 10 kg/m; - the max. wall-thickness proportion (S max/S min) of 3,5 mm. In the case of profiles which, due to the complexity of their design, are difficult to manufacture and specify, then special agreements between supplier and purchaser may need to be reached.NOTE The effect of the thermal barrier material on the dimensional tolerances is covered by this document although the actual thermal barrier material itself is not (see EN 14024).

This document establishes the general principles to be adopted to minimize the effects of stray currentcorrosion caused by direct-current (d.c.) on buried or immersed pipeline systems. A brief description ofalternating current (a.c.) effects is provided.The document is intended to offer guidance for:— the design of cathodic protection systems which may produce stray currents;— the design of pipeline systems, or elements of pipeline systems, which are to be buried or immersed and which may be subject to stray current corrosion;— the selection of appropriate protection or mitigation measures.The effects of a.c. induced voltages are not dealt with in detail in this document because they arecovered in ISO 18086. General principles and guidelines are, however, provided.Stray current corrosion can also occur internally in systems containing a conducting electrolyte e.g.near insulating joints or high resistance pipe joints in pipelines transporting conductive fluids.Internal corrosion risks from stray currents are not dealt with in detail in this document but principlesand measures described here can be applicable for minimizing the interference effects.Stray currents can also cause other effects such as overheating. These other effects are not covered inthis document.A.C. currents can induce unacceptable touch voltages on above-ground appurtenances of pipelinesystems. These are not covered in detail in this document. They are covered in EN 50443, EN 61140,IEC 60364-4-41, IEC TS 60479-1, IEC 60364-5-52, IEC /TS 61201, and IEC TR 60479-5.Systems which may be affected by stray currents include buried or immersed metal structures such as:a) pipeline systems;b) metal sheathed cables;c) tanks and vessels;d) earthing systems;e) steel reinforcement in concrete;f) sheet steel piling.This document provides details only for pipeline systems although the principles can be applied toother buried structures.
