FormPlanet project has published two CEN workshops agreements (CWAs) with the objective to standardise two novel testing methodologies that allow to characterise sheet metal properties and predict part performance.
The two agreements are the result of eight months of work by the members of the CEN Workshop: “Innovative testing in support of the sheet metal forming industry”, which was launched in December 2020, and constituted a successful collaboration between various European organisations which have joined forces to achieve a common goal.
- “Test method for determination of the essential work fracture of thin ductile metallic sheets” (CWA 17793:2021): This CWA defines the test procedure for the evaluation and characterisation of the plane stress fracture toughness in thin metallic sheets, being this procedure based on the Essential Work of Fracture (EWF) methodology. The document provides the guidelines for specimen preparation, testing and data post-processing as well as the limitations of the method.
- “Measurement of diffusible hydrogen in metallic materials – HELIOS 4 HOT PROBE method” (CWA 17794:2021): The document specifies and offers a set of guidelines and recommendations for the measurement of diffusible hydrogen content in steel sheets, that can be susceptible to hydrogen embrittlement phenomenon.
The elaboration of the to CWAs has followed several stages, through a consensus-based process that always ensures openness, transparency and participation, and which has involved all CEN/WS FormPlanet participants in a first step, and all the other interested European organisations in a second phase. Since the launch of FormPlanet CEN Workshop, the partners responsible for the CWAs drafting have been working in order to adapt some of the project’s results into the programmed standardisation documents according to the European standardisation common practices and rules.
Standardisation in FormPlanet project
UNE, the Spanish standardisation association, leads the activities related with standards within FormPlanet, with the main objective to increase the visibility and impact of the project, as well as to contribute to the acceptance and utilisation by the market of the developed solutions. The standardisation activities help to ensure the quality and generate confidence among the future users of the FormPlanet Open Innovation Test Bed (OITB) services and related metallic products.
