This European Standard specifies requirements for execution of structural steelwork as structures or as manufactured components, produced from:

—    hot rolled, structural steel products up to and including grade S690;

—    cold formed components and sheeting up to and including grades S700 (unless coming within the scope of prEN 1090‑4);

—    hot finished or cold formed austenitic, austenitic-ferritic and ferritic stainless steel products;

—    hot finished and cold formed structural hollow sections, including standard range and custom-made rolled products and hollow sections manufactured by welding.

For cold formed components, sheeting, and cold formed structural hollow sections that are within the scope of prEN 1090‑4, the requirements of prEN 1090‑4 take precedence over corresponding requirements in this European Standard.

This European Standard may also be used for structural steel grades up to and including S960, provided that conditions for execution are verified against reliability criteria and any necessary additional requirements are specified.

This European Standard specifies requirements, which are mostly independent of the type and shape of the steel structure (e.g. buildings, bridges, plated or latticed components) including structures subjected to fatigue or seismic actions. Certain requirements are differentiated in terms of execution classes.

This European Standard applies to structures designed according to the relevant part of the EN 1993 series. With respect to the execution of piling designed to EN 1993‑5, this European Standard applies to the execution of anchors, walings, bracings, connections and fabricated piles but does not supersede the execution requirements given in EN 12699 or EN 14199.

This European Standard applies to steel components in composite steel and concrete structures designed according to the relevant part of the EN 1994 series.

This European Standard may be used for structures designed according to other design rules provided that conditions for execution comply with them and any necessary additional requirements are specified.

This European Standard includes the requirements for the welding of reinforcing steels to structural steels. This European Standard does not include the execution of reinforcing steels for concrete applications.

This European Standard is applicable for the preparation of representative test portions from the laboratory sample that has been taken as specified in respective product standards and in CEN/TR 16220, prior to testing of release and analysis of content of construction products.

This European Standard is intended to specify the sequence of operations and treatments to be applied to the laboratory sample in order to obtain suitable test portions in compliance with the specific requirements defined in the corresponding test methods and analytical procedures.

This European Standard covers the design of devices that are provided in structures, with the aim of modifying their response to the seismic action. It specifies functional requirements and general design rules for the seismic situation, material characteristics, manufacturing and testing requirements, as well as evaluation of conformity, installation and maintenance requirements. This European Standard covers the types of devices and combinations thereof as defined in 3.4.

NOTE          Additional information concerning the scope of this European Standard is given in Annex A.

This European Standard specifies requirements for the following types of screed material as defined in EN 13318:

—    Cementitious;

—    Calcium sulphate;

—    Magnesite;

—    Mastic asphalt;

—    Synthetic resin.

All types of screed material may be used for internal applications.

Cementitious screed material may be used for both internal and external applications.

This European Standard specifies the performance for fresh and hardened screed materials.

The floor screed materials could be monolayer or multilayer.

This European Standard specifies the assessment and verification of the constancy of performance and the classification and designation of screed materials.

This European Standard does not provide criteria or recommendations for the design and installation of screed materials.

This European Standard specifies sampling and test methods for natural, artificial and recycled aggregates for use as armourstone. This European Standard specifies the reference methods to be used for type testing and in case of dispute where an alternative method has been used. For other purposes, in particular factory production control, other methods may be used provided that an appropriate working relationship with the test method has been established.
