equipment within the fields of audio/video, information technology and communication technology, was
submitted simultaneously to the formal vote.
The combined texts were approved by CENELEC as amendment A1 to EN 60950-1:2006 on
2010-03-01.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN and CENELEC shall not be held responsible for identifying any or all such patent
rights.
The following dates were fixed:
– latest date by which the amendment has to be implemented

at national level by publication of an identical
(dop) 2011-03-01
national standard or by endorsement
– latest date by which the national standards conflicting
with the amendment have to be withdrawn (dow) 2013-03-01

1.2.3 Add the following definition:
1.2.3.Z1
PORTABLE SOUND SYSTEM
small battery powered audio equipment:
− whose prime purpose is to listen to recorded or broadcasted sound; and
− that uses headphones or earphones that can be worn in or on or around the ears; and
− that allows the user to walk around
NOTE Examples are mini-disk or CD players; MP3 audio players or similar equipment.
1.7.2.1 Delete NOTE Z1.
Add the following paragraph at the end of the subclause:
In addition, for a PORTABLE SOUND SYSTEM, the instructions shall include a warning that
excessive sound pressure from earphones and headphones can cause hearing loss.
4.3.13.6 Replace the existing NOTE by the following:
NOTE Z1 Attention is drawn to :
1999/519/EC: Council Recommendation on the limitation of exposure of the general public to electromagnetic fields
0 Hz to 300 GHz, and
2006/25/EC: Directive on the minimum health and safety requirements regarding the exposure of workers to risks
arising from physical agents (artificial optical radiation).
Standards taking into account mentioned Recommendation and Directive which demonstrate compliance with the
applicable EU Directive are indicated in the OJEC.

Bibliography Add the following note for the standard indicated:
