This European

17、Standard has been prepared by the CEN/CENELEC Joint Working Group on Active Implantable Medical Devices (CEN/CLC JWG AIMD). Members of the Joint Working Group were nominated by one of the members of either CEN or CENELEC. This European Standard has been prepared under mandates given to CEN and CENEL

18、EC by the Commission of the European Communities and the European Free Trade Association, and supports the essential requirements of Directive 90/385/EEC Council Directive of June 1990 on the approximation of the laws of the Member states relating to active implantable medical devices. Although both

19、 this Particular Standard and the Directive deal with the same products, the structure and purpose of the two documents are different. Annex AA of this Particular Standard correlates the requirements of the Directive with the subclauses of EN 45502-1:1997 and of this Particular Standard. Annex BB pr

20、ovides references in the other direction, from this European Standard to the Directive. Annex CC is a rationale providing some further explanation of the subclauses of this Particular Standard. _ BS EN 45502-2-2:2008EN 45502-2-2:2008In this standard, the following print types are used: Requirements

21、and definitions: roman type. Test specifications: italic type. Informative material appearing outside of tables, such as notes, examples and references: in smaller type. Normative text of tables is also in a smaller type. TERMS DEFINED IN CLAUSE 3 OF THE GENERAL STANDARD, IN THIS PARTICULAR STANDARD

22、 OR AS NOTED: SMALL CAPITALS. In referring to the structure of this standard, the term “clause” means one of the seventeen numbered divisions within the table of contents, inclusive of all subdivisions (e.g. Clause 7 includes Subclauses 7.1, 7.2, etc.); “subclause” means a numbered subdivision of a

23、clause (e.g. 7.1, 7.2 and 7.2.1 are all subclauses of Clause 7). References to clauses within this standard are preceded by the term “Clause” followed by the clause number. References to subclauses within this collateral standard are by number only. In this standard, the conjunctive “or” is used as

24、an “inclusive or” so a statement is true if any combination of the conditions is true. The verbal forms used in this standard conform to usage described in Annex H of the ISO/IEC Directives, Part 2. For the purposes of this standard, the auxiliary verb: “shall” means that compliance with a requireme

25、nt or a test is mandatory for compliance with this standard; “should” means that compliance with a requirement or a test is recommended but is not mandatory for compliance with this standard; “may” is used to describe a permissible way to achieve compliance with a requirement or test. - 3 - Contents
