Standard specifying elevator behaviour before, during, and after seismic events.
Full Definition
ISO 8100-32 (formerly EN 81-77) specifies requirements for lifts in seismic conditions: seismic detectors (P-wave and S-wave), controlled return to nearest floor, and post-earthquake inspection before return to service. Design requirements include rope sway guards, increased guide clearances, and strengthened equipment fixing. Installations are categorised by seismic zone and building importance factor.
