Foreword
The text of document 29/777/FDIS, future edition 1 of IEC 60601-2-66, prepared by IEC/TC 29
"Electroacoustics" was submitted to the IEC-CENELEC parallel vote and approved by CENELEC as
The following dates are fixed:
(dop) 2013-08-06
• latest date by which the document has
to be implemented at national level by
publication of an identical national
standard or by endorsement
(dow) 2015-11-06
• latest date by which the national
standards conflicting with the
document have to be withdrawn
This standard is to be read in conjunction with EN 60601-1:2006.

In this standard, the following print types are used:
- Requirements 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 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 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 particular standard are by number only.

In this standard, the conjunctive “or” is used as 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 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 AA.
