Requirements for escalator and moving-walk speed have appeared in the ASME A17.1/CSA B44 standards since 2000 (Requirements 6.1.4.1 and 6.2.4.1). The A17.1 code, prior to harmonization in 2000, contained requirements for escalator speed since 1921 (Rule 610a). The maximum permitted speed of an escalator was reduced from 125 to 100 fpm in the 2000 edition…
