Scope:

These requirements cover robots and robotic equipment rated 600 V or less and intended for installation in accordance with the National Electrical Code, NFPA 70. Since end-use installation of a robot and robotic equipment may vary for each user application, guidelines for end-product installation may be evaluated to the applicable sections of ISO 10218-1, Robots and Robotic Devices – Safety Requirements for Industrial Robots – Part 1 and ISO 10218-2, Robots and Robotic Devices -- Safety Requirements for Industrial Robots -- Part 2: Robot Systems and Integration.

These requirements cover robotic equipment and systems intended for indoor and outdoor use in applications such as parts assembly, parts transfer, automated material handling, inspection, loading, die-casting, deburring, welding, paint spraying, clinical/diagnostic systems, pharmaceutical applications, commercial food processing, automated vehicle refueling systems, library book handling/sorting, clean room applications, medical use , mobile robots, personal care robots, Automated Guided Vehicles (AGVs), automated storage/retrieval systems, and the like. 

Robots and robotic equipment that contain unique features or functions associated with the application or end-product equipment, and not specifically addressed in this standard or referenced standards, shall also be evaluated to the applicable requirements of those standards. 

In addition to the requirements in this Standard, robots and robotic systems shall also comply with the applicable sections of the Electrical Standard for Industrial Machinery, NFPA 79. 

Robots and robotic systems intended for use in hazardous locations, as defined by the National Electrical Code, NFPA 70, shall also comply with the applicable safety requirements based on the specific end-use application, including those contained in the following standards:

a) Intrinsically Safe Apparatus and Associated Apparatus for Use in Class I, II, and III, Division 1, Hazardous (Classified) Locations, UL 913;

b) Explosion-Proof and Dust-Ignition-Proof Electrical Equipment for Use in Hazardous (Classified) Locations, UL 1203;

c) Nonincendive Electrical Equipment for Use in Class I and II, Division 2 and Class III, Divisions 1 and 2 Hazardous (Classified) Locations, ISA 12.12.01;

d) Electric Motors and Generators for Use in Hazardous (Classified) Locations, UL 674; and

e) Purged and Pressurized Enclosures for Electrical Equipment, NFPA 496.

In the following text, a requirement that applies to one type of equipment, such as a controller or pendant, will be identified by a specific reference. In the absence of a specific reference or if the term robot or robotic equipment is employed, it is to be understood that the requirement applies to all types of equipment covered by this Standard
