EN81-20

Ensuring compliance with various codes and regulations is about doing things properly. EN81-20 is no exception. All our elevators at Next Level Elevators comply with standards.

Released in 2014, new safety standards replaced the old EN81-1 standard. These changes brought to us by the European Committee of Standardisation are about strengthening lift safety, with technology and knowledge in mind.

Changes:

  • Ascending car overspeed and UCM (Unintended Car Movement) related requirements build upon a safety-first culture for passengers. They address the risk of a car moving away from the landing. Requirements for protection against ascending car overspeed have also been strengthened. Today, they cover rescue operations.
  • Another change concerns door detection systems. New standards require elevators to include a curtain of light mechanism (a non-contact detection system). The design must prevent doors from closing when an obstruction is detected. As such, photocell-based mechanisms are not compliant with new standards. These changes reduce the risk of doors hurting entering and exiting passengers
  • Also strengthened are the requirements for car floors, walls, and ceilings. Materials must meet stricter fire classification requirements.
  • Doors must now include retainers to guarantee door panels are in place. Mandatory testing regarding impact must cover car and landing doors.
  • Higher levels of lighting for the car interior and the shaft are now essential for both accessibility needs and passenger safety.
  • Safety enhancements for service technicians are a priority. The goal is to make access to the elevator machine room and working in the pit safer and easier. A control station is to be in the pit, for example. There must also be a reset function outside the shaft.
  • The new standard requires access or inspection doors (not inspection “trapdoors”) to meet safety guidelines for technicians.
  • Regarding volumes requirements: Car roof and pit refuge spaces have increased.
  • Balustrades located on the elevator car roof must meet updated and defined strength/height requirements.
  • Any horizontal projection (ledge) must be protected so that an individual cannot stand on it.
  • All glass used in the elevator shaft must be laminated. Sprinklers can be used in the shaft. The responsibility of shaft ventilation now falls on the building designer

Keep in mind that the above is an overview. For more specifics regarding the new standards, interested customers are encouraged to read the official EN 81-20:2014 standards documents.

Note: Elevators put in operation before 1. September 2017 are not affected by the latest code.
