The basic objectives of the Stahl-Eisen-Blätter are:
- Description of the latest technologies to ensure the quality of processes and products
- Description of the property profiles of steels for which standardisation is not yet possible
- Standardisation of the test conditions and description of material properties of different eel groups
- Documentation of the available expert knowledge
- Consideration of the specific requirements of the steel industry
- Consensus-building by the experts
- Accelerating of the implementation of new knowledge into application
- Preliminary work for DIN, CEN and/or ISO standards
Every expert and every company or research institution which is interested in these Stahl-Eisen- Blätter has the unrestricted opportunity to contribute in the work. It is requested that the Stahlinstitut VDEh be informed immediately if any inaccuracies or the possibility of incorrect interpretation become apparent in the application of the sheets, so that any deficiencies can be rectified.
Stahl-Eisen-Prüfblätter [test specifications] (SEP)
SEP contain guidelines and information on the proper implementation of tests to determine certain material properties and characteristic values of steels. The purpose of the SEP is to standardise the test conditions in pre-standardisation in such a way that the test results are comparable when used properly. SEP are often incorporated into customer specifications and contribute significantly to reducing the testing effort for steel producers and -users. Customers in the steel industry require such characteristic values, e. g. for the construction or technical security of components (lightweight construction, resource conservation).
Stahl-Eisen-Werkstoffblätter [material specifications] (SEW) und -Lieferbedingungen [delivery conditions] (SEL)
SEW and SEL serve to standardise the functional characteristics of steels in pre-standardisation. Both the knowledge of steel producers and steel users are taken into account regarding the application. The purpose of SEW and SEL is to describe the property profiles of steels for which standardisation has not yet taken place, but which are important for steel producers, -processors and -users. This description is intended to enable a targeted use of the steels and at the same time to gather knowledge about their production, delivery and application and their product forms.
Stahl-Eisen-Einsatzblätter [appropriate usage] (SEE)
According to current knowledge, SEE serve as a recommendation for the appropriate selection of steels for tools used in certain forming processes.
Stahl-Eisen-Betriebsblätter [operating sheets] (SEB)
Special requirements of the steel industry are defined in SEB in order to standardise the planning, production, assembly and maintenance of metallurgical plants and thus be able to carry them out safely and economically. According to SEB, the interchangeability with regard to the connecting dimensions is also guaranteed. In addition to dimensions, materials and calculation methods, they also contain specifications for ordering, delivery and quality assurance. They also consider the issues of occupational safety and environmental protection for the operation of plants.
