Basic Information
Scope
This document specifies the reliability technical requirements and test requirements for speed limiters, safety clutches, buffers, door locking devices, elevator drive motors, elevator drive motor brakes, wire rope brakes, door machine systems, suspension devices, rope end assemblies, counterweight blocks, light curtains, non-metallic pulleys, buttons, leveling switches, guide shoes, compensation devices, trailing cables, control devices, drive devices, safety circuits containing electronic components, programmable electronic safety-related systems (PESSRAL) for elevators, escalators, and moving walkways, escalator and moving walkway drive motors, escalator and moving walkway drive motor brakes, handrail belts, rollers, stair/pedal chains, drive chains, stair/pedals, floor panels, and comb-support plates, additional brakes, control devices, drive devices, and safety circuits containing electronic components, and programmable electronic safety-related systems (PESSRAE) for escalators and moving walkways. The components specified in this document are applicable to traction-driven passenger elevators and freight elevators, escalators, and moving walkways. In special circumstances (such as potential explosive environments, extreme climatic conditions, high altitudes, exposure to sunlight, wind, snow, or corrosive air, etc.), additional requirements must be considered in addition to the requirements of this section.
