This document specifies the special provisions and safety rules for passenger and goods passenger lifts where these lifts are permanently installed in buildings that are in compliance with EN 1998-1 (Eurocode 8). This document defines additional requirements to EN 81-20 and EN 81-50. It applies to new passenger lifts and goods passenger lifts. However, it can be used as a basis to improve the safety of existing passenger and goods passenger lifts. This document does not introduce any additional special provisions and safety rules for lifts which are in Seismic lift category 0 as defined in Annex A, Table A.1. This document does not address other risks due to seismic events (e.g. fire, flood, explosion).
