BS EN ISO _百度文库

When the machinery contains various elements that can be operated independently, the control system shall be designed to prevent risks arising out of a lack of coordination for example, collision prevention system. When the reliability of particular components or assemblies is critical for safety for example, ropes, chains, lifting accessories for lifting loads or personsstress limits shall be multiplied by appropriate working coefficients.

For details of these and other benefits contact Membership Administration. Hazardous event Contact with objects with high or low temperature Emission of a substance that can be hazardous Subclause of this International Standard 6. When, in order for the operator to maintain permanent control of deceleration, this principle is not observed for example, a hydraulic braking device of a self-propelled mobile machinethe machine shall be equipped with a means of slowing and stopping in case of failure of the main braking system.

You may experience issues viewing this site in Internet Explorer 9, 10 or ISO is intended to be used together with ISO when considering the solution to a specific problem. The use of colours should be considered, particularly in relation to components requiring quick identification. Compliance with a British Standard does not of itself confer immunity from legal obligations. Such signals may also be used to warn the operator before the triggering of automatic protective measures see last paragraph of 5.

Disturbances which can be generated by those conditions are, e. This International Standard is the basis for a set of standards which has the following structure: While automatic feeding and removal devices have much to offer in preventing accidents to machine operators, they can create danger when any faults are being rectified.

Where, for describing a hazard, more than one of the columns presented in Table B. Iteration of this process can be necessary to eliminate hazards as far as practicable and to adequately reduce risks by the implementation of protective measures.

Readily understandable signs pictograms should be used in preference to written warnings. These principles and methods shall be applied singly or in combination as appropriate to the circumstances see ISO and IEC Guidance is given on the documentation and verification of the risk assessment and risk reduction process.

The warning devices shall be designed and located such that checking is easy. Such tasks shall be identified and considered in the risk assessment as parts of the use of the machine see ISO This publication does not purport to include all the necessary provisions of bz contract. Validation comprises testing and analysis e. General principles eh design or a Type C standard eg BS Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. General requirements for the design and construction of fixed and movable guards deals specifically with the guarding design, but the subject is also covered to a lesser extent in EN ISO Clause 5.

When determining these elements, it is necessary to take into account the aspects given in 5. BSI also holds the copyright, in the UK, of the publications of the international standardization bodies. This document supersedes EN In some cases, it ej enough to use only one of the columns, particularly lso hazards are in the same hazard zone and can be grouped together in terms of protective measures.

Several methods are available for the systematic identification of hazards. When it is foreseen that a machine will be put to non-professional use, the instructions should be written in a form that is readily understood by the non-professional user.

Safety of machinery: EN ISO 12100-1 and EN ISO 12100-2

Applying principle ios positive mechanical action 6. Whenever possible, control devices and control positions shall be located so that the operator is able to observe the working area or hazard zone.

This means that the characteristics and performances of the machine or a series of machines in an integrated process, and the related people, environment and products, should be identified in terms of the limits of machinery as given in 5.

These three steps are:. This term is included as basic terminology for type-B and type-C standards. The exposure of a person is often the consequence of performing a task on the machine.

The driver of a ride-on mobile machine shall be able to actuate all control devices required to operate the machine from the driving position, except for functions which can be controlled more safely from other positions. NOTE It also improves the performance and reliability of the operation and hence it reduces the probability of errors at all stages of machine use. Stability shall be considered in all phases of the life cycle of the machine, including handling, travelling, installation, use, dismantling, disabling and scrapping.

Safety of Machinery: EN ISO and EN ISO

A combination of safeguards may sometimes be required. IEC defines the detection capability of electrosensitive protective equipment. Standards or other specifications used to select protective measures referred to in f above should be referenced.

This covers everything from ‘machinery’, ‘hazard’ and ‘risk’ to ‘adequate risk reduction’, ‘common cause failures’ and ‘common mode failures.
