IFEK - Ferrous metals

This part of this European Standard specifies the technical delivery conditions for forgings for pressure purposes, made of ferritic and martensitic steels with specified elevated temperature properties. Chemical composition and mechanical properties are specified.
NOTE   Once this standard is published in the EU Official Journal (OJEU) under Directive 2014/68/EU, presumption of conformity to the Essential Safety Requirements (ESRs) of Directive 2014/68/EU is limited to technical data of materials in this standard and does not presume adequacy of the material to a specific item of equipment. Consequently, the assessment of the technical data stated in this material standard against the design requirements of this specific item of equipment to verify that the ESRs of Directive 2014/68/EU are satisfied, needs to be done. The series EN 10222-1 to EN 10222-5 is structured so that the data related to different materials is in the part allocated for that material. The presumption of conformity to the Essential Safety Requirements of Directive 2014/68/EU depends on both the text in part 1 and the data in part 2, 3, 4 or 5.
General information on technical delivery condition is given in EN 10021.

This part of this European Standard specifies technical delivery conditions for hot-finished seamless, electric welded and submerged arc welded steel structural hollow sections for mechanical engineering purposes of circular, square, rectangular or elliptical forms.
It applies to hollow sections formed hot, with or without subsequent heat treatment, or formed cold with subsequent heat treatment above 580 °C to obtain equivalent mechanical properties to those obtained in the hot formed product.
NOTE 1   The requirements for tolerances, dimensions and sectional properties are specified in EN 10210-2.
NOTE 2   The attention of users is drawn to the fact that whilst cold formed grades in EN 10219-3 can have equivalent mechanical properties to hot-finished grades in EN 10210-3 the sectional properties of square and rectangular hollow sections in EN 10210-2 and EN 10219-2 are not equivalent.
NOTE 3   A range of material grades is specified in this document and the user should select the grade most appropriate to the intended use and service conditions. The grades and mechanical properties of the finished hollow sections are generally comparable with those in EN 10025-2, EN 10025-3, EN 10025-4, EN 10025-5 and EN 10025-6.

Certain steel grades covered by ISO 16143‑2 are also used for springs, although to a much lesser extent. In these cases, the mechanical properties (tensile strength, etc.) will be agreed between purchaser and supplier. Similarly, diameters between 10,00 mm and 15,00 mm can be ordered according to the specifications of this part of ISO 6931, in which case the parties will agree upon the required mechanical characteristics.

This document specifies a method using a barcoding system for tracing potential 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 at transferring additional material information to the steel users, especially the location of some isolated defects, in a reliable way. This method enables the manufacturer or purchaser to eliminate 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 [1]) 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.
