An example of this is positive opening operation of switching devices in an electrical circuit see IEC —1 and ISO The interfaces between zones shall be designed such that no function in one zone creates hazards in another zone which has been stopped for an intervention. Technical principles ISO These 12010-2 should be supplemented with written details enabling, for example, manual controls actuators to be located and identified.
This applies to power systems operative part as well as to control systems, to safety functions as well as to other functions of machinery. The selector may be replaced by another selection isp which restricts the use of certain functions of the machinery to certain categories of operators e.
Safety of machinery: EN ISO 12100-1 and EN ISO 12100-2
Fifty documents are listed but, as has been shown above, some of these have since been with withdrawn and superseded. Factors to be taken into account when estimating the possibility of avoiding or limiting harm are, among others, the following: If standardized or other suitable measurement methods exist for an emission, they should be used, in conjunction 1200-2 existing machinery or prototypes, to determine emission values and comparative emission data.
The necessary aids for access shall be provided e. Safeguarding and complementary protective measures Step 3: When estimating risk, those components and systems identified as immediately increasing the risk in case of failure need special iwo.

Practical guidance and examples of methods ‘ is intended to assist designers in complying with EN ISO by providing additional guidance on the selection of appropriate protective measures for achieving safety.
More details for the design and selection of electrical components and elements to achieve the emergency stop function are provided in IEC Information for use a? In truth, however, it is likely that almost every machine builder that does not currently own a copy will find something of use in both parts. For example, where, in conjunction with a fixed guard, a mechanical loading feeding device is used to feed a workpiece into a machine, thereby removing the need for access to the primary hazard zone, a trip device can be required to protect against the secondary drawing-in or shearing hazard between the mechanical loading feeding device, when reachable, and the fixed guard.
YES NO a The first time the question is asked, it is answered by the result of the initial risk assessment. Components shall be selected taking into account all factors mentioned above see also 4.
In order to prevent hazardous machine behaviour and to achieve safety functions, the design of control systems shall comply with the principles and methods presented in this subclause 6.
All reasonably foreseeable hazards, hazardous situations or hazardous events associated with the various tasks shall then be identified. Complementary protective measures involving additional equipment e. This International Standard is also intended to be used as a basis for the preparation of type-B or type-C safety standards. Markings shall comply with recognized standards for example, ISO or ISOfor pictograms, symbols and colours in particular.
YES At each step of ieo iterative process: Signs and pictograms should only be used if they are understood in the culture in which the machinery is to be used. Each position of the selector shall be clearly identifiable and shall exclusively allow one control or operating mode. Typical examples of hazardous machine behaviour are?
Controls shall be so arranged that their layout, travel and resistance to operation are compatible with the lso to be performed, taking account of ergonomic principles.
For each type of hazard or group of hazards, some potential consequences can be related to several origins of hazard. Designers’ attention is especially drawn to following ergonomic aspects of machine design: Endorsement notice The text of ISO Human interactions with displays and control actuators  ISOErgonomic principles related to mental work-load – General terms and definitions  ISOErgonomic principles related to mental workload – Part 2: Accept and continue Learn more about the cookies we use and how to change your settings.
Such tasks shall be identified and considered in the risk assessment as parts of the use of the machine see ISO This does not preclude the free use, in the course of implementing the standard, of necessary details such as symbols, and size, type or grade designations. In some cases, it is enough to use only one of the columns, particularly when hazards are in the same hazard zone and can be grouped together in terms of protective measures.
Certain safeguards may be used to avoid exposure to more than one hazard e. Electrical hazards For the design of the electrical equipment of machines, IEC gives general provisions about disconnection and switching of electrical circuits and for protection against electric shock. Users are responsible for its correct application. Certain safeguards may be used to avoid exposure to more than one hazard.
