This European Standard specifies requirements for the execution of aluminium structural components and structures made from: a) rolled sheet, strip and plate; b) extrusions; c) cold drawn rod, bar and tube; d) forgings; e) castings. NOTE 1 The execution of structural components is referred to as manufacturing, in accordance with EN 1090-1. This European Standard specifies requirements independent of the type and shape of the aluminium structure, and this European Standard is applicable to structures under predominantly static loads as well as structures subject to fatigue. It specifies requirements related to the execution classes that are linked with consequence classes. NOTE 2 Consequence classes are defined in EN 1990. NOTE 3 Recommendations for selection of execution class in relation to consequence class are given in EN 1999-1-1. This European Standard covers components made of constituent products with thickness not less than 0,6 mm for welded components not less than 1,5 mm. For components made from cold formed profiled sheeting that are within the scope of FprEN 1090-5, the requirements of FprEN 1090-5 take precedence over corresponding requirements in this European Standard. This European Standard applies to structures designed according to the relevant parts of EN 1999. If this European Standard is used for structures designed according to other design rules or used for other alloys and tempers not covered by EN 1999, a judgement of the reliability elements in these design rules should be made. This European Standard specifies requirements for surface preparation prior to application of a protective treatment, and gives guidelines for application for such treatment in an informative annex. This European Standard gives options for specifying requirements to match project specific requirements. This European Standard is also applicable to temporary aluminium structures.
