European foreword
This document (EN 60670-22:2006/A11:2024) has been prepared by CLC/TC 23BX "Switches, boxes and
enclosures for household and similar purposes, plugs and socket outlet for D.C.".
The following dates are fixed:
• latest date by which this document has to be (dop) 2025-07-29
implemented at national level by publication of
an identical national standard or by
endorsement
• latest date by which the national standards (dow) 2027-07-29
