The CEN Workshop ‘Innovative testing in support of the sheet metal forming industry’ is a result of the currently ongoing Horizon 2020 FormPlanet project (Sheet metal forming testing hub), whose general objective is to develop and demonstrate an integrated ecosystem offering novel testing methodologies to characterise metal sheet properties, predict part performance and prevent production loses to the sheet forming industries to tackle the upcoming challenges in formability of processing sensitive materials.
In the future, a Test Bed service provision will be offered through a solid, sustainable and simple organisational structure, based on the partners' experience and FormPlanet results, e.g. CWAs developed by this CEN/WS, with strong business focus.
The scope of the CEN/WS is to develop novel testing methodologies that allow to characterise metal sheet properties and predict part performance.
The Workshop has published two CWAs according to this scope:
- CWA 17793:2021 ‘Test method for determination of the essential work of fracture of thin ductile metallic sheets’
This CWA describes the procedure for the evaluation of the plane stress fracture toughness of thin ductile metallic sheets by means of the EWF methodology. The document provides the guidelines for specimen preparation, testing and data post-processing as well as the limitations of the method. - CWA 17794:2021 ‘Measurement of diffusible hydrogen in metallic materials - HELIOS 4 HOT PROBE method’
This CWA provides a set of guidelines for the measurement of diffusible hydrogen content in steel sheets, that can be susceptible to hydrogen embrittlement phenomenon.
