CENELEC members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard
11、 without any alteration. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the Central Secretariat or to any CENELEC member. This European Standard exists in three official versions (English, French, German). A version in any other l

Incorporating corrigendum April 2009- 2 - Foreword T
14、his European Standard was prepared by the CEN/CENELEC Joint Working Group on ACTIVE IMPLANTABLE MEDICAL DEVICES (CEN/CLC JWG AIMD). The text of the draft was submitted to the formal vote and was approved by CENELEC as EN 45502-2-2 on 2007-05-01. This European Standard, together with EN 45502-2-1:200
15、3, supersedes EN 50061:1988 + A1:1995 (+ corrigendum October 1995). The following dates were fixed: latest date by which the EN has to be implemented at national level by publication of an identical national standard or by endorsement (dop) 2008-10-01 latest date by which the national standards conf

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
