It also incorporates the Amendments ISO These principles shall be considered when allocating functions to operator and machine degree of automation in the basic design. The programmable electronic control system should be installed and validated to ensure that the specified performance e.
Materials and substances or physical factors temperature, noise, vibration, radiation and environment? Indeed, the ISO website states that both parts are to be revised, though no timescale is given. Measures which can be incorporated at the design stage are preferable to those implemented by the user and usually prove more effective.
This can be achieved by the measures given in 6. The walking areas shall be made from materials which remain as slip resistant as practicable under working conditions and, depending on the height from the ground, suitable guard-rails see ISO shall be provided. NOTE 2 Adequate protective measures associated with each of the operating modes and intervention procedures reduce the possibility of operators being induced to use hazardous intervention techniques in case of technical difficulties.
The information for use shall include, but not be limited to, the following: A hazardous event can have different causes. Automation can be achieved e.
Safety of machinery: EN ISO 12100-1 and EN ISO 12100-2
This International Standard is also intended to be used as a basis for the preparation of type-B or type-C safety standards. It may be useful to mark them “keep for future reference”. The process itself is iterative and several successive applications can be necessary to reduce the risk, making the best use of available technology.
YES At each step of the iterative process: If personal protective equipment is required for the safe use of the machine, clear advice should be bw, for example, on the packaging as well as on the machine, so that this information is prominently displayed at the point of sale.
Has the risk been a adequately reduced? 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.

Control systems shall be designed to enable the operator to interact with the machine safely and easily; this requires one or several of the following solutions: This applies to power systems operative part as well as to control systems, to safety functions as well as to other functions of machinery.
Although efforts 122100-2 made to maintain a balance between the emphases of these individual standards, some compromises have been made. In order to allow the proper action to be initiated, component failure shall be detected by automatic monitoring see 6.
1210-2 Each position of the selector shall be clearly identifiable and shall exclusively allow one control or operating mode. Factors to be taken into account when estimating the occurrence of a hazardous event are, among others, a b c d reliability and other statistical data, accident history, history of damage to health, and comparison of risks see 5.
Disturbances which can be generated by those conditions are, e. The selector may be replaced by another selection means which restricts the use of certain functions of the machinery to certain categories of operators for example, uso codes for certain numerically controlled functions. Examples of hazards Origina acceleration, deceleration; angular parts; approach of a moving element to a fixed part; cutting parts; elastic elements; falling objects; gravity; height from the ground; high pressure; instability; kinetic energy; machinery mobility; moving elements; rotating elements; rough, slippery surface; sharp edges; stored energy; vacuum.
Once this standard is cited in the Official Journal of the European Union under that Directive and has been implemented as a national standard in at least one Member State, compliance with the normative clauses of this standard confers, within the limits of the scope of this standard, a presumption of conformity with the relevant Essential Requirements of that Directive and associated EFTA regulations.
When the reliability of particular components or assemblies is critical for safety e. Signs and pictograms should only be used if they are understood in the culture in which the machinery is to be used.
Other protective measures for stability relevant to safeguarding are given in 6.
Standardized phrases shall be considered where important messages such as warnings are given see also IEC Standards are also available from the BSI website at http: General principles for design and testing of pressure-sensitive mats and pressure-sensitive floors EN  ISOSafety of machinery — Prevention of unexpected start-up EN  ISOSafety of bx — Interlocking devices associated with guards – Principles for design and selection EN 2 Isl European standard and the International standard are not strictly identical.
NOTE In some countries the use of specific language vs is covered by legal requirements. Protective devices shall be installed and connected to the control system so that they cannot be easily defeated.
For quantitative analysis, data from databases, handbooks, laboratories or manufacturers’ specifications may be used, provided that there is confidence isi the suitability of the data. Falling or ejection of objects 6. After switching on the power supply, or when the machine has been stopped by the tripping function of the sensitive protective equipment, the machine cycle shall be initiated only by voluntary actuation of a start control.
This International Standard is the basis for a set of standards which has the following structure: Fifty documents are listed but, as has been shown above, some of 1210-2 have since been with withdrawn and superseded.
Risk assessment is a series of logical steps to enable, in a systematic way, the analysis and evaluation of the risks associated with machinery. NOTE Isolation and energy dissipation for machine shut-down see 6. Information for use consists of communication links, such as texts, words, signs, signals, symbols or diagrams, used separately or in combination to convey information to the user.
Safety-relevant instructions which involve immediate action should be provided in a form readily available to the operator. BSI offers members an individual updating service called PLUS which ensures that subscribers automatically receive the latest editions of standards.
Whenever possible, control devices and control positions shall be located rn that the operator 1210-2 able to observe the working area or hazard zone.

If these details are to be used for any other purpose than implementation then the prior written permission of BSI must be obtained. For example, where, in conjunction with a fixed 121002, 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.
The following provisions are intended to provide the designer with criteria for selecting, for each application, 12100-2 most suitable device s.
