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. Equipment evaluated to these requirements is intended to meet the requirements of Robots and Robotic Devices - Safety Requirements for Industrial Robots - Part 1@ ISO 10281-1@ and can be installed in accordance with 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@ 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 or referenced standards@ shall also be evaluated to the applicable requirements of standards for the application or end-product equipment. 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.
