Foreword The text of document 62A/564/FDIS, future edition 1 of IEC 62353, prepared by SC 62A, Common aspects of electrical equipment used in medical practice, of IEC TC 62, Electrical equipment in medical practice, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 62353 on 2007-09-11. 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)
2008-08-01 – latest date by which the national standards conflicting
with the EN have to be withdrawn
(dow)
2010-10-01 In this standard, the following print types are used: – requirements and definitions: roman 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 USED THROUGHOUT THIS STANDARD THAT HAVE BEEN DEFINED IN CLAUSE 3: IN SMALL CAPITALS. 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 requirement 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. An asterisk (*) as the first character of a title or at the beginning of a paragraph or table title indicates that there is guidance or rationale related to that item in Annex A.
Annex ZA has been added by CENELEC. __________ Endorsement notice The text of the International Standard IEC 62353:2007 was approved by CENELEC as a European Standard without any modification. In the official version, for Bibliography, the following notes have to be added for the standards indicated: IEC 60335 NOTE
