One of the most significant objectives of the EuReDatA association is the establishment of compatible standards for reliability data collection and analysis. This is being pursued by specialized project groups. By starting with the proposal of general reference classification schemes for component reliability and the issue of a guide for reliability data collection and analysis, the project groups’ activity has moved in more recent times towards data analysis exercises and feasibility studies for data collection projects.

As enunciated by the Constitutional Agreement, the EuReDatA Association was formed to harmonize research and development work in the field of Reliability Data Banks, in particular by promoting the adoption of agreed definitions and procedures aimed at the exchange of information and experience on reliability data acquisition among Members. Given this objective, the Association parties realized immediately the difficulties resulting from this ambitious project. It was, in fact, a matter of forming a common language permitting the exchange of data among Members coming from various European countries and, what is more, involved in different fields of industrial activity where the user’s needs were often largely different. To solve the problems arising from the organization and control of the large effort which could have been required to meet this objective, various ad-hoc project groups were created to work out solutions for specific topics. This paper describes the effort made and the results obtained by such specialized groups which have already produced reports that could be utilized by people active in an ever-widening variety of disciplines to facilitate the useful exchange of reliability information among them.
