6.1.4 Rated Speed
(a) The acceleration and deceleration rates shall not exceed 0.3 m/s2 (1.0 ft/s2).
(b) The rated speed is not exceeded.
(c) The minimum speed shall be not less than 0.05 m/s (10 ft/min).
(d) The speed shall not automatically vary during inspection operation.
(e) Passenger detection means shall be provided at both landings of the escalator such that
(2) detection of any approaching passenger shall occur sufficiently in advance of boarding to cause the escalator to attain full operating speed before a passenger walking at normal speed [1.35 m/s (270 ft/min)] reaches the combplate
(3) it shall remain active at the egress landing to detect any passenger approaching against the direction of escalator travel and shall cause the escalator to accelerate to full rated speed and sound the alarm (see 22.214.171.124.1) at the approaching landing before the passenger reaches the combplate
