Foreword
After publication of IEC 61540:1997, Portable residual current devices without integral overcurrent protection
for household and similar use (PRCDs), the Secretariat Enquiry CLC/TC 23E(SEC)64 was launched. The
th
comments of the national committees were considered at the 14 meeting of CLC/TC 23E, where it was
decided to ask the CENELEC Technical Board for permission to prepare common modifications in the form
of a Harmonization Document (HD), a European Standard (EN) being not possible because the
requirements related to the plug and socket-outlet parts of PRCDs make reference to national standards.
This decision was approved by in July 1999 by the 100 BT, who recalled that the HD can only be included in
the list of publications ensuring compliance with the 73/23/EEC directive (see BT decisions D100/076 and
D100/077).
A draft containing common modifications to the text of IEC 61540:1997 and its amendment 1:1998 was
submitted to the formal vote and was approved by CENELEC as HD 639 S1 on 2001-07-01.
The following dates were fixed:
– latest date by which the existence of the HD
has to be announced at national level (doa) 2001-12-31
– latest date by which the HD has to be implemented
at national level by publication of a harmonized
national standard or by endorsement (dop) 2002-10-01
– latest date by which the national standards conflicting
with the HD have to be withdrawn (dow) 2005-06-01
Annexes designated "normative" are part of the body of the standard.
In this standard, annexes A, B, C, D, ZA and ZB are normative.
Annexes ZA and ZB have been added by CENELEC.
In this standard, the following print types are used:
- requirements: in roman type;
- test specifications: in italic type;
- notes: in smaller roman type.
