These requirements cover robots and robotic equipment rated 600 V or less and intended for installation in accordance with the National Electrical Code@ ANSI/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 the Robotic Industries Association (RIA) Standard for Industrial Robots and Robot Systems ?C Safety Requirements@ ANSI/RIA R15.06. 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@ diecasting@ 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 for surgery@ mobile robots@ automated guided vehicles@ automated storage etrieval 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@ shall also be evaluated to the requirements of the other applicable 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@ ANSI/NFPA 79. Robots and robotic systems intended for use in hazardous locations@ as defined by the National Electrical Code@ ANSI/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) Industrial Control Equipment for Use in Hazardous (Classified) Locations@ UL 698; c) Explosion-Proof and Dust-Ignition-Proof Electrical Equipment for Use in Hazardous (Classified) Locations@ UL 1203; d) Electrical Equipment for Use in Class I and II@ Division 2@ and Class III Hazardous (Classified) Locations@ UL 1604; e) Electric Motors and Generators for Use in Division 1 Hazardous (Classified) Locations@ UL 674; and f) 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 teach 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.
