This document is a type C standard as stated in ISO 12100-1. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this document. When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards for machines that have been designed and built according to the provisions of this type C standard. Hazards associated with robots are well recognized, but the sources of the hazards are frequently unique to a particular robot system. The number and type(s) of hazard(s) are directly related to the nature of the automation process and the complexity of the installation. The risks associated with these hazards vary with the type of robot used and its purpose and the way in which it is installed, programmed, operated and maintained. NOTE 1 Not all of the hazards identified by ISO 10218 apply to every robot and nor will the level of risk associated with a given hazardous situation be the same from robot to robot. Consequently the safety requirements and/or protective measures may vary from what is specified in ISO 10218. A risk assessment may be conducted to determine what the protective measures should be. In recognition of the variable nature of hazards with different uses of industrial robots, ISO 10218 is divided into two parts; Part 1 provides guidance for the assurance of safety in design and construction of the robot. Since safety in the application of industrial robots is influenced by the design and application of the particular robot system integration, Part 2 will provide guidelines for the safeguarding of personnel during robot integration, installation, functional testing, programming, operation, maintenance and repair. NOTE 2 While noise is generally considered a hazard associated with the industrial environment, the robot as defined in 3.18 cannot be considered the final machine, rather the robot system as defined in 3.20 is the machine for noise consideration. Therefore the hazard due to noise will be dealt with in ISO 10218-2. ISO 10218 is not applicable to robots which were manufactured prior to its publication date. BS EN ISO 10218-1:2006 Licensed Copy: London South Bank University, South Bank University, 16/11/2008 11:24, Uncontrolled Copy, (c) BSI 1 Robots for industrial environments Safety requirements Part 1: Robot 1 Scope This part of ISO 10218 specifies requirements and guidelines for the inherent safe design, protective measures and information for use of industrial robots, as defined in Clause 3. It describes basic hazards associated with robots and provides requirements to eliminate, or adequately reduce, the risks associated with these hazards. Noise as a potential hazard is not dealt with in this part of ISO 10218, but will be fully covered in Part 2. This part of ISO 10218 does not apply to non-industrial robots although the safety principles established in ISO 10218 may be utilized for these other robots. Examples of non-industrial robot applications include, but are not limited to: undersea, military and space robots, tele-operated manipulators, prosthetics and other aids for the physically impaired, micro-robots (displacement 250 mm/sec can be achieved. In this case, the robot shall: a) have a means to select manual high speed mode which requires a deliberate action (e.g. a key switch on the robot control panel) and an additional confirming action; b) default to a speed u 250 mm/sec upon selection of manual high speed mode; c) provide a pendant conforming to 5.8 with an additional hold to run device, exclusive to this mode, that permits robot motion to continue; d) provide on the pendant a means to adjust the speed from the default value to the full programmed value; and e) provide on the pendant an indication of the adjusted speed (e.g. by a highlight on the pendant display). NOTE 1 This optional manual mode has previously been known as T2, or high-speed programme verification. NOTE 2 B, C, D, E. 5.8 Pendant controls 5.8.1 General Where a pendant control or other control device has the capability to control the robot from within the safeguarded space, the requirements in 5.8.2 to 5.8.7 shall apply. NOTE This applies to any device used to control a robot from within the safeguarded space while drive power is applied to any of the robot axes. This includes robots with powered lead-through teach, whether using robot-mounted manual controls or main/secondary teaching controls. 5.8.2 Motion control Motion of the robot initiated from the pendant or teaching control device shall be under reduced speed control as described in 5.6. When the pendant contains provisions for selecting higher speeds, the robot system shall meet the requirements in 5.7.4. All buttons and other devices on the pendant that cause robot motion shall stop motion when the button or device is released. NOTE B, D, E.

The enabling device shall demonstrate the following performance characteristics: a) the enabling device may be integral with, or physically separate from (e.g. a grip-type enabling device), the pendant control and shall operate independently from any other motion control function or device; b) release of or compression past the centre-enabled position of the device shall stop hazards (e.g. robot motion) in accordance with 5.4; c) when more than one enabling switch is used on a single enabling device (i.e. allowing alternating left and/or right hand operation), fully depressing any switch shall override the control of the other switches and cause a protective stop; d) when more than one enabling device is in operation (i.e. more than one person are in the safeguarded space with an enabling device), motion shall only be possible when each device is held in the centre (enabled) position at the same time; e) dropping the enabling device shall not result in a failure that would allow motion to be enabled; and f) if an enabling output signal is provided, then the output shall signal stop condition when the safety system supply is off and shall comply with the requirements of 5.4. NOTE 1 Design and installation of the enabling device should consider the ergonomic issues of sustained activation. NOTE 2 Additional information on enabling may be found in Annex C. NOTE 3 B, D, E. 5.8.4 Pendant emergency stop function The pendant or teaching control device shall have a stop function in accordance with 5.5.2. The presentation of the device shall be an emergency stop device as described in ISO 13850. NOTE A, E. 5.8.5 Initiating automatic operation It shall not be possible to activate robot automatic operation using the pendant or teaching control device exclusively. A separate confirmation outside the safeguarded space shall be necessary prior to activating the automatic mode. NOTE B, D, E. 5.8.6 Cableless teach controls Where pendant or other teaching controls have no cables connecting to the robot control, the following shall apply: a) a visual indication shall be provided that the pendant is active, e.g. at the teach pendant display; b) loss of communication shall result in a protective stop for all robots when in manual reduced speed or manual high speed modes. Restoration of communication shall not restart robot motion without a separate deliberate action; BS EN ISO 10218-1:2006 Licensed Copy: London South Bank University, South Bank University, 16/11/2008 11:24, Uncontrolled Copy, (c) BSI 14 c) the maximum response times for data communication (including error correction) and for loss of communication shall be stated in the information for use; and d) care shall be taken to avoid confusion between active and inactive emergency stop devices by providing for appropriate storage or design, and information for use. NOTE A, C, D, E. 5.8.7 Control of multiple robots Where a pendant control has the capability to control multiple robots, the requirements in 5.9 shall apply. NOTE A, B, E. 5.9 Control of simultaneous motion 5.9.1 Single pendant control One or more robot controls can be linked to a single teach pendant. When so configured, the teach pendant shall have the capability to move one or more of the robots independently or in simultaneous motion. When in the manual operational mode, all functions of the robot system shall be under the con
