This part of EN 508 specifies requirements for self-supporting products for roof covering, wall cladding, lining, liner tray and tile products for discontinuous laying made from stainless steel sheets with or without additional metallic and/or organic coatings. Sheets intended to be used with insulation and membranes are also covered.
This document establishes general characteristics, definitions, classifications and labelling for the products, together with requirements for the materials from which the products can be manufactured. It is intended to be used either by manufacturers to ensure that their products comply with the requirements or by purchasers to verify that the products comply before they are dispatched from the factory. It specifies the requirements for products which enable them to meet all normal service conditions.
This document applies to all discontinuously laid self-supporting external profiled sheets for roof covering, wall cladding, lining, liner trays and tile products with the exception of tiles with a surface area less than 1 m2 and produced by stamping. These profiled roof sheets are designed to keep wind, rain and snow out of the building and to transfer any resultant loads and infrequent maintenance loads to the structure.
This document does not cover products for structural purposes, i.e. it does cover products used in structural class III (according to EN 1993-1-3), it does not cover products used in constructions of structural classes I and II (according to EN 1993-1-3) intended to contribute to the global or partial stability of the building structure by providing racking resistance or resistance to permanent static loads (excluding self-weight of the metal sheet).
No requirements for supporting construction, design of roof or cladding, lining, tile system and execution of connections and flashings are included.

This document specifies a method for determination of the biaxial stress-strain curve of metallic
sheets having a thickness below 3 mm in pure stretch forming without significant friction influence. In
comparison with tensile test results, higher strain values can be achieved.

This document specifies a method for determining the tensile strain hardening exponent n of flat
products (sheet and strip) made of metallic materials.
The method is valid only for that part of the stress-strain curve in the plastic range where the curve is
continuous and monotonic (see 8.4).
In the case of materials with a serrated stress-strain curve in the work hardening range (materials
which show the Portevin-Le Chatelier effect, e.g. AlMg-alloys), the automatic determination (linear
regression of the logarithm true stress vs. the logarithm true plastic strain, see 8.7) is used to give
reproducible results.

This document specifies a method using a barcoding system for tracing isolated defects that can be present in the following kinds of coated or uncoated steel flat products, for example:
- electro-galvanised surface;
- galvanised surface;
- galvannealed surface;
- cold rolled surface.
This method, named "quality tracking", aims to transfer additional material information to steel users, in particular the location of some isolated defects, in a reliable way. This method enables the manufacturer or purchaser to remove blanks or coils containing defects.
The method uses a 1D barcode to identify each section of steel strip.
NOTE 1 The stakeholders most involved in this technique are suppliers of steel flat products, car makers, appliance makers, part manufacturers, blanking line builders, steel processors, service centres, etc. All stakeholders can benefit from this project since defects can be traced, and, therefore, the steel containing defects can be eliminated or set apart of the production line.
NOTE 2 In the first stages of development, this method was called "defect tracking" (see [3]) and has been changed into "quality tracking" at the beginning of the standardization process.
NOTE 3 Quality tracking can be applied to other types of coated or uncoated steel flat products such as pickled and oiled, organic coated, and steels for packaging. Quality tracking can be applied for coiled materials for which the technology of quality tracking is applicable.
NOTE 4 If quality tracking data are used outside of the purpose of quality tracking, it is under the responsibility of the user.
NOTE 5 Quality tracking can be applied to other materials than steel.
NOTE 6 The way to collect the information to be transferred to the user is out of the scope of this document.

- thicknesses ≤ 250 mm for flat and long products of all other grades and qualities.
The steels specified in this document are not intended to be heat treated except products delivered in the delivery condition +N. Stress relieving is accepted. Products delivered in +N condition can be hot formed and/or normalized after delivery (see Clause 3).
This document foresees that semi-finished products which are to be converted to rolled finished products conforming to this document are the subject of special agreements at the time of the order. The chemical compositions are also agreed to at the time of the order; the values are within the limits of Tables 1 and 2.

Products made of steel grades S185, E295, E335 and E360 cannot be CE marked.
The steels specified in this Part 2 are not intended to be heat treated except products delivered in delivery condition +N. Stress relief annealing is permitted (see also the NOTE in 7.3.1.1 of EN 10025-1:2004). Products delivered in +N condition can be hot formed and/or normalized after delivery (see Clause 3).
NOTE 1 Semi-finished products which are to be converted to rolled finished products conforming to this document should be the subject of special agreement at the time of the enquiry and order. The chemical composition can also be agreed at the time of the order, however the values should be within the limits of Tables 2 and 3.
NOTE 2 For certain grades and product forms suitability for particular applications may be specified at the time of the enquiry and order (see 7.4.2, 7.4.3 and Table 10).

This part of EN 10225 specifies requirements for weldable structural steels to be used in the fabrication of fixed offshore structures in the form of plates.
Following thickness limitations are given in this standard:
- S355NL1O up to and including 200 mm;
- S355ML1O, S420ML1O, S460ML1O, S500ML1O up to and including 120 mm;
- S420QLO, S460QLO, S500QLO, S550QLO, S620QLO, S690QLO up to and including 150 mm.
Greater thicknesses may be agreed, provided the technical requirements of this European Standard are maintained.
The standard is applicable to steels for offshore structures, designed to operate in the offshore sector but not to steels supplied for the fabrication of subsea pipelines, risers, process equipment, process piping and other utilities. It is primarily applicable to the North Sea Sector, but may also be applicable in other areas provided that due consideration is given to local conditions e. g. temperature.
NOTE There is an Annex F on the prequalification of steels for fixed offshore structures in arctic areas.
Minimum yield strengths up to 690 MPa are specified together with low temperature impact properties at temperatures down to -40 °C.
