Clause 5, ‘Safeguarding and complementary protective measures,’ contains plenty of information that will be useful to machine designers 121001 a day-to-day basis. This makes it possible for the designer to? NOTE 1 This stage is the only one at which hazards can be eliminated, thus avoiding the need for additional protective measures such as safeguarding or complementary protective measures.

NOTE The different kinds of guards and protective devices are defined in 3. For detailed consideration of the fault behaviour of, for example, active optoelectronic protective 121001, IEC should be taken into account. See IEC as regards marking of electrical equipment. Manually adjustable guards shall be?

In order to allow the proper action to be initiated, component failure shall be detected by automatic monitoring see 6. It also provides a strategy for standard makers. 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.

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

Amendment 1 affects hazard identification, risk estimation and risk evaluation and adds additional references. A list of organizations represented on this committee can be obtained on request to its secretary. The faster, easier way to work with standards. All protective measures intended for reaching this objective shall be applied in the following sequence, 12100-11 to as the three-step method see also Figures 1 and 2.


Such measures include, but are not limited to, those dealt with in 6.

The following provisions are intended to provide the designer with criteria for selecting, for each application, the most suitable device s. Learn more about the cookies we use and how to change your settings.

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.

Stability shall be considered in all phases of the life cycle of the machine, including handling, travelling, installation, use, dismantling, disabling and scrapping.

The concept of safety of machinery considers the ability of a machine to perform its intended function s during its lifecycle where risk has been adequately reduced. Validation comprises testing and analysis for example, static, dynamic or failure analysis to show that all parts interact correctly to perform the safety function and that unintended functions do not occur. 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.

Achieving the objectives of risk reduction and a favourable outcome of risk comparison applied when practicable gives confidence that risk has been adequately reduced. Information for use shall not be a substitute for the correct application of inherently safe design measures, safeguarding or complementary protective measures.

NOTE Isolation and energy dissipation for machine shut-down see 6. Other protective measures for stability relevant to safeguarding are given in 6. Constraints due to the necessary or foreseeable use of personal protective equipment such as footwear, gloves shall be taken into account.


Guidance is given on the documentation and verification of the risk assessment and risk reduction process. 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. Specify hs limits and the intended use of the machine; Identify the hazards and associated hazardous situations; Estimate the risk, for each identified hazard and hazardous situation; Evaluate the risk and take decisions about the need for risk reduction; Eliminate the hazard or reduce the risk associated with the hazard by protective 121001.

These three steps are:. Hazards other than emissions that are described by measurable parameters can be dealt with in a similar manner. EN ISO Part 2 of the standard Technical principles generally contains practical advice that can be implemented when designing machinery.

Factors to be taken into account include?

Basic concepts, general principles for design. However, all hazards should be documented even if the risk associated with them appears to have been sufficiently reduced by a protective measure ido for reducing the risk associated with another hazard.

A combination of safeguards can sometimes be required. Another fundamental concept that is introduced in Clause 5. The use of one or more of the columns presented in Table B. Users are responsible for its correct application. This may be enn by use of embedded software in a non-reprogrammable memory [for example, micro-controller, application-specific integrated circuit ASIC ].

Their committees work with the manufacturing and service industries, government, businesses and consumers to facilitate the production of British, European and International standards.
