38、nical Committee CEN/TC 135 “Execution of steel structures and aluminium structures”, the secretariat of which is held by SN. 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 2008, and conf
39、licting national standards shall be withdrawn at the latest by December 2008. 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. Accordin
40、g to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,

BS EN 1090-3:2008EN 1090-3:2008 (E) 8 Introduction This European Standard specifies requirements for the execution of aluminium structures, in order to
42、 ensure adequate levels of mechanical resistance and stability, serviceability and durability. This European Standard specifies requirements for the execution of aluminium structures in particular those that are designed according to EN 1999-1-1, EN 1999-1-2, EN 1999-1-3, EN 1999-1-4 and EN 1999-1-5
43、. This European Standard presupposes that the work is carried out with the necessary skill and adequate equipment and resources to perform the work in accordance with the execution specification and the requirements of this European Standard. BS EN 1090-3:2008EN 1090-3:2008 (E) 9 1 Scope This Europe
44、an 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,
45、 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 relat
46、ed 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 pro
47、ducts with thickness not less than 0,6 mm for welded components not less than 1,5 mm. 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 a
48、nd 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 informa
49、tive annex. This European Standard gives options for specifying requirements to match project specific requirements. This European Standard is also applicable to temporary aluminium structures.
