This part of ISO/TS 25740:

  • specifies global essential safety requirements (GESRs) for escalators and moving walks, their components and functions, and

  • establishes a system and provides methods for minimizing safety risks that might arise in the course of the operation and use of, or work on, escalators and moving walks.

NOTE See Clause 5 regarding the use and application of this part of ISO/TS 25740.

This part of ISO/TS 25740 is applicable to escalators and moving walks that are intended to carry persons. The escalators and moving walks to which this part of ISO/TS 25740 applies can:

  1. be located in any permanent and fixed structure or building;

  2. have any

    1. rated load, size of load carrying unit (LCU) and speed, and

    2. travel height;

  3. be affected by fire in the environment of the LCU and weather conditions;

  4. be misused.

This part of ISO/TS 25740 does not specifically cover:

  • all needs of users with disabilities1);

  • risks arising from work on escalators and moving walks under construction or during alterations and dismantling; vandalism; fire in the environment outside the LCU.
