The work of preparing International Standards
24、is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take pa
25、rt in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to
26、prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility th

According to the CEN/CENELEC Inter

BS EN ISO 13849-2:2008 ISO 13849-2:2003(E) vi ISO 2003 All rights reserved Introduction For the use in the European Union, this part of EN ISO 13849 has the status of a generic safety standard (type B1). This European Standard specifies the validatio
40、n process, including both analysis and testing, for the safety functions and categories for the safetyrelated parts of control systems. Descriptions of the safety functions and the requirements for the categories are given in EN 954-1 (ISO 13849-1) which deals with the general principles for design.
41、 Some requirements for validation are general and some are specific to the technology used. EN ISO 13849-2 also specifies the conditions under which the validation by testing of the safety-related parts of control systems should be carried out. EN 954-1 (ISO 13849-1) specifies the safety requirement
42、s and gives guidance on the principles for the design see EN 292-1:1991 (ISO/TR 12100:1992), 3.11 of the safety-related parts of control systems. For these parts it specifies categories and describes the characteristics of their safety functions, regardless of the type of energy used. Additional adv
43、ice on EN 954-1 (ISO 13894-1) is given in CR 954-100 (ISO/TR 13849-100). The achievement of the requirements can be validated by any combination of analysis (see clause 4) and testing (see clause 5). The analysis should be started as early as possible within the design process. BS EN ISO 13849-2:200
44、8 ISO 13849-2:2003(E) ISO 2003 All rights reserved 1 1 Scope This European Standard specifies the procedures and conditions to be followed for the validation by analysis and testing of: the safety functions provided, and the category achieved of the safety-related parts of the control system in comp
45、liance with EN 954-1 (ISO 13849-1), using the design rationale provided by the designer. This European Standard does not give complete validation requirements for programmable electronic systems and therefore can require the use of other standards. NOTECEN/TC 114/WG 6 proposes to deal in more detail
46、 with the validation of programmable electronic systems in the elaboration of the revision to EN 954-1 (ISO 13849-1). An application standard for machinery (draft IEC 62061), based on IEC 61508, is under preparation. Requirements for programmable electronic systems, including embedded software, are
47、given in IEC 61508. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent am
48、endments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments). EN 292-1:1991 (ISO/TR 12100:1992), Safety of machinery
