The A-RDP brings together all relevant standardisation activities and their status, and is updated regularly in order to maintain visibility and awareness of the progress. It provides a database to support the identification and discussion of overlaps, and as a basis for feedback to contributing organisations, to improve overall coordination of standards developments.
The A-RDP focusses on the SES and regulatory-related standardisation activities and is periodically updated to reflect the current situation based on the best available information. It may therefore not be exhaustive in some areas. Its content should be used for information purposes only.
