What is the connection between EN 303645, EN 18031 and RED?

Due to the security requirements of RED being regulatory requirements announced in 2021, there were no supporting test standards at that time. The industry temporarily used the industry standard EN 303645 as a transitional test standard. Since the official release of the EN 18031 standard, from a regulatory perspective, EN 303645 is no longer associated with RED security, although some test items have similar requirements. The EN 18031 standard will serve as the test standard for RED security.
