8、for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has t
9、he right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The pro

16、 of ISO machinery safety standards. It identifies the different kinds of documents in ISO (see Table B.1) and explains the type-A, type-B and type-C structure of machinery safety standards and their interrelationship with regard to the practical design of machinery subjected to adequate risk reducti

However, it does not provide specification of the general content that is expected to be included in the different types of machinery safety standards. This specificatio
18、n is given in ISO Guide 78.

27、ery; type-B standards (generic safety standards) dealing with one safety aspect or one type of safeguard that can be used across a wide range of machinery; type-C standards (machine safety standards) dealing with detailed safety requirements for a particular machine or group of machines. As shown in
28、 Figure 1, ISO 12100 is the type-A standard specifying the general principles for safety of machinery and applies to all machinery.

29、e-A standard (ISO 12100) The type-A standard ISO 12100 specifies the principle strategy for safety of machinery. Risk assessment and adequate risk reduction by an iterative three-step method are the imperative measures to design a machine to achieve a level of tolerable risk. To implement risk asses
30、sment and risk reduction, the following actions should be taken by the designer in the order given (see Figure 2): a) determine the limits of the machinery, which includes the intended use and any reasonably foreseeable misuse thereof; b) identify the hazards and associated hazardous situations; c)
31、estimate the risk for each identified hazard and hazardous situation; d) evaluate the risk and decision whether a risk reduction is needed or not; e) eliminate the hazard or reduction of the risk associated with the hazard by means of protective measures/risk reduction measures. NOTE 1 For the purpo
32、ses of this Technical Report, the terms “protective measure” (see ISO 12100:2010, 3.19) and “risk reduction measure” are synonymous and referred to any action or means used to eliminate hazards and/or reduce risks.2 ISO 2015 All rights reserved ISO/TR 22100-1:2015(E) Actions a) to d) are related to
33、risk assessment and action e) to risk reduction. Risk assessment is a series of logical steps to enable, in a systematic way, the identification of hazards as well as the estimation and evaluation of the risks associated with machinery. As a result of the risk assessment, the hazards requiring risk
34、reduction are determined. Iteration of the process of risk assessment can be necessary to eliminate newly generated hazards as far as reasonably practicable or to adequately reduce associated risks by the implementation of protective measures/risk reduction measures in order to achieve tolerable ris
35、k. Protective measures/risk reduction measures are the combination of the measures implemented by the designer and the user in accordance with Figure 3. Measures which can be incorporated at the design stage are preferable to those implemented by the user and usually prove more effective. The object
36、ive to be met is the greatest practicable risk reduction. The strategy defined in this clause is represented by the flowchart in Figure 2. The process itself is iterative and several successive applications can be necessary to reduce the risk, making the best use of available technology. In carrying
37、 out this process, it is necessary to take into account these four factors, in the following order of preference: the safety of the machine during all the phases of its life cycle; the ability of the machine to perform its function; the usability of the machine; the manufacturing, operational and di
38、smantling costs of the machine. NOTE 2 The ideal application of these principles requires knowledge of the machine design and its intended use, the practical use of the machine, the accident history and health records, available risk reduction techniques, and the legal framework in which the machine
39、 is intended to be used (placed on the market).

42、user. c There is no hierarchy between the various protective measures implemented by the user. These protective measures are outside the scope of this part of ISO/TR 22100. d Those protective measures required due to specific process(es) not envisaged in the intended use of the machine or to specifi

44、s deal either with one safety aspect (type-B1 standard) or one type of safeguard that can be used across a wide range of machinery (type-B2 standard). Type-B standards are intended to support the principle strategy from ISO 12100 in order to help determine if a hazard exists, for example, ISO 13857,

Type-B1 standards can be used directly by the designer/manufacturer or by referen
