BS EN 1090-3:2019

This standard BS EN 1090-3:2019 Execution of steel structures and aluminium structures is classified in these ICS categories:

• 91.080.13 Steel structures
• 77.150.10 Aluminium products
• 91.080.17 Aluminium structures

This document 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 document specifies requirements independent of the type and shape of the aluminium structure, and this document 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 document 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 EN 1090-5, the requirements of EN 1090-5 take precedence over corresponding requirements in this document. This document applies to structures designed according to the relevant parts of EN 1999. If this document 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 is intended to be made. This document 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 document gives options for specifying requirements to match project specific requirements. This document is also applicable to temporary aluminium structures.
