This standard is for barrier-free vertical lifting equipment in public buildings such as residences, hospitals, shopping malls, etc., clarifying the core technical requirements such as platform size, safety protection devices, electrical interlocking, and emergency rescue, and refining the adaptation standards for different usage scenarios. The standard is linked with the EU Disability Rights Protection Act, requiring that all barrier-free vertical access facilities supporting new public buildings and residences in the EU must complete compliance transformation by the end of 2026, and products that do not meet the standard will be prohibited from entering the EU market. This standard has also become an important reference specification in the field of global accessible elevators.
