This part of GB 11291 specifies safety requirements for the integration of industrial robots and industrial robot systems as defined in GB 11291.1, and industrial robot cells. The integration includes the following:
a) the design, manufacturing, installation, operation, maintenance and decommissioning of the industrial robot system or cell;
b) necessary information for the design, manufacturing, installation, operation, maintenance and decommissioning of the industrial robot system or cell;
c) component devices of the industrial robot system or cell.
This part describes the basic hazards and hazardous situations identified with these systems, and provides requirements to eliminate or adequately reduce the risks associated with these hazards. Although noise has been identified to be a significant hazard with industrial robot systems, it is not considered in this part. This part also specifies requirements for the industrial robot system as part of an integrated manufacturing system. This part does not deal specifically with hazards associated with processes (e.g. laser radiation, ejected chips, welding smoke). Other standards can be applicable to these process hazards.

3 Terms and Definitions
For the purposes of this document, the following terms and definitions apply.
3.1
application
intended use of the robot system, i.e. the process, the task and the intended purpose of the robot system
Example: Spot welding, painting, assembly, palletizing.
3.2
collaborative robot
robot designed for direct interaction with a human within a defined collaborative workspace (3.3)
3.3
collaborative workspace
workspace within the safeguarded space where the robot and a human can perform tasks simultaneously during production operation
3.4
control station
part of the robot system which contains one or more control devices intended to activate or deactivate functions of the system or parts of the system
Note: The control station can be fixed in place (e.g. control panel) or movable (e.g. control pendant).
3.5
distance guard
guard that does not completely enclose a danger zone, but which prevents or reduces access by virtue of its dimensions and its distance from the danger zone
Example: Perimeter fence or tunnel guard.
3.6
integration
act of combining a robot with other equipment or another machine (including additional robots) to form a machine system capable of performing useful work such as production of parts
Note: This act of machine building can include the requirements for the installation of the system.
3.7
integrator
entity that designs, provides, manufactures or assembles robot systems or integrated manufacturing systems and is in charge of the safety strategy, including the protective measures, control interfaces and interconnections of the control system
Note: The integrator can be a manufacturer, assembler, engineering company or the user.
3.8
integrated manufacturing system (IMS)
group of machines working together in a coordinated manner, linked by a material-handling system, interconnected by controls (i.e. IMS controls), for the purpose of manufacturing, treatment, movement or packaging of discrete parts or assemblies
