There is no strict speed classification for elevators, and it is customary in China to classify them according to the following method.
Low speed elevator: often refers to an elevator with a speed lower than 1.00m/s.
Medium speed elevator: often refers to an elevator with a speed between 1.00 and 2.00m/s.
High speed elevator: often refers to an elevator with a speed greater than 7m/s.
