1 Scope

These requirements cover the safety of the robotic function of Service, Communication, Information, Education and Entertainment (SCIEE) robots.

These requirements supplement the safety requirements for the intended, non-robotic product function as described in the relevant identified standard(s) and, where applicable, cover robotics intended for indoor and outdoor use.

The scope includes service robots intended for commercial use applications where ongoing operation of the robot does not require instructed or skilled person intervention during operation.

Note 1: See UL 62368-1, “Principles of this product safety standard” in Clause 0 for an explanation of ordinary, instructed and skilled persons.

Note 2: Where an instructed person initiates / configures the robot (e.g. educational settings) is not considered to be intervention during operation.

These requirements do not apply to:

1. – Robots intended to treat, alleviate instability or move individuals in hospitals, care facilities or in the home.

2. – Robots operated exclusively for industrial purposes.

3. – Material-handling robots for use in restricted environments.

4. – Robots for on- or off-road transport of persons.

5. – Robots intended for use in a food establishment except where the robot serves as a conveyance to directly relinquish food to the consumer

6. Note: Food establishment is defined in the US FDA Food Code

7. – Robots for which safety of the robotic function is described in the relevant end-product safety standard.

8. Examples of such standards include:

   1. – Commercial floor cleaning machines covered by ANSI/CSA C22.2 No. 336, Particular requirements for rechargeable battery-operated commercial robotic floor treatment machines with traction drives.

   2. – Portable battery-operated automatic vacuums covered by UL 1017, Standard for Vacuum Cleaners, Blower Cleaners, and Household Floor Finishing Machines

9. – Robots identified as a toy by the manufacturer and intended for play only by children covered by the Standard for Electric Toys, UL 696 and/or ASTM F963, Standard Consumer Safety Specification for Toy Safety.

10. – Robots intended for use in hazardous locations

11. – Robots intended for use as personnel protective equipment

12. Note: Additional requirements may be necessary for robots

    1. – with parts in contact with food or potable water

    2. – with parts in contact with persons such that biocompatibility is a consideration.

    3. – subject to occupational safety and health regulation

    4. – intended for use aboard aircraft, watercraft and road vehicles

    5. – that perform as or are integrated in security or life safety systems
