Safety of Machinery: EN ISO and EN ISO
This can be caused by, for example: NOTE 1 Annex B gives, in separate tables, examples of hazards, hazardous situations and hazardous events, in order to clarify these concepts and assist the designer in the process of hazard identification. Readily understandable signs pictograms should be used in preference to written warnings. Other protective measures for stability relevant to safeguarding are given in 6. Information for use consists of communication links, such as texts, words, signs, signals, symbols or diagrams, used separately or in combination bw convey information to the user.
NOTE In some cases, it will be necessary to take additional measures to limit the negative effects of such a failure. Where, for describing a hazard, more than one of the columns presented in Table B. When estimating risk, those components and systems identified as immediately increasing the risk in case of failure need special attention.
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.
Various BSI electronic information services are also available which give details on all its products and services. NOTE A fixed guard can be hinged to assist in its opening.

These three steps are: The work of preparing International Standards is normally carried out through ISO technical committees. These judgments shall be supported by a qualitative or, where appropriate, quantitative estimate of 121000-2 risk associated with the hazards present on the machinery. Account shall be taken of body sizes likely to be found in the intended user population, strengths and postures, movement amplitudes, frequency ba cyclic actions see ISO and ISO Mechanization can be achieved by, for example, feeding slides, push-rods and hand-operated indexing tables.
Each position of the selector shall be clearly identifiable and shall exclusively allow one control or operating mode. Such measures include, but are eb limited to, is dealt with in 6. They shall provide the minimum possible interference with activities during operation and other phases of machine life, in order to reduce any incentive to defeat them.
Factors to be taken into account include: Basic concepts, general principles for design. The selector may be replaced by another selection means which restricts the use of certain functions of the machinery to certain categories of operators e.

Ba shall be selected taking into account all factors mentioned above see also 4. Break-up during operation 6. All reasonably foreseeable hazards, hazardous situations or hazardous events associated with the various tasks shall then be identified.
Requirements for the location and operation of actuators  IECSafety of machinery — Electrosensitive protective equipment — Part 1: For example, when a band saw used? The elements of guards and of protective devices shall be particularly reliable, as their failure can expose persons to hazards, and also as poor reliability would encourage attempts to defeat them. This second edition cancels and replaces ISO You may find similar items within these categories by selecting from the choices below:.
If additional hazards do occur, they shall be added to the list of identified hazards and appropriate protective measures will be required to address them.
Clause 4, ‘Hazards to be taken into account when designing machinery,’ can be treated as an extensive checklist of hazards, ranging from mechanical, electrical and thermal hazards to hazards generated by noise, vibration and ‘neglecting bd principles in machine design. This reset shall be possible only at the location where the emergency stop command has been initiated.

When the application requires reprogramming by the user, the access to the software dealing with safety functions should be restricted for example, by locks or passwords for the authorized persons. The walking areas shall 21100-2 made from materials which remain as slip resistant as practicable under working conditions and, depending on the height from the ground, shall be provided with suitable guard-rails see ISO Automatic monitoring either detects a fault immediately or carries out periodic checks so that a fault is detected before the next demand upon the safety function.
This applies especially to machines which can be manually controlled by means among others of a portable control unit teach pendant, for instancewith which the operator may enter danger zones.
The objective to be met is the greatest practicable risk reduction, taking into account the four below factors. Factors to be taken into account include?
