Scope

Scope: This standard specifies the basic requirements, institutional requirements, personnel and equipment requirements, verification timing, verification preparation, action speed requirements, filling out of verification records, conclusion determination, format and marking of verification reports for the verification of elevator speed limiters. This standard applies to the verification of speed limiters for traction and forced-drive elevators, hydraulic-driven elevators, and service elevators listed in the Special Equipment Catalogue. For speed limiters used in other types of elevators, their verification can be referred to this standard. Main technical content: Elevator speed limiters are very important safety protection devices for the safe operation of elevators. Whether they can function normally is a prerequisite and guarantee for the safe operation of elevators. In order to clarify the action speed range of speed limiters, standardize the verification behavior of elevator speed limiters, and improve the quality of elevator speed limiter verification work. 1.
