• RS-ME; ME-RS
• IT-ME; ME-IT
• MK-RS; RS-MK
• BG-MK; MK-BG

To register, please reply to this email with the following information:

• Company name (registered companies only)
• EIC code
• Username (if already registered in eCAT) or full name
• Email address

Please note that registration will close on October 31st, 2025.

Further details regarding timing, access, and specific testing scenarios will be shared in a follow-up communication.

If you have any questions or feedback, feel free to reach out. Your participation and insights are highly appreciated.

Best regards,
