Zx.2 Equipment requirements 
No safety provision is required for equipment that 
complies with the following: 
− equipment provided as a package (personal 

music player with its listening device), where 

  the acoustic output L

Aeq,T 

is ≤ 85 dBA measured 

while playing the fixed “programme 

  simulation noise” as described in EN 50332-1; 

and 

− a personal music player provided with an 
  analogue electrical output socket for a listening 
  device, where the electrical output is ≤ 27 mV 
  measured as described in EN 50332-2, while 
  playing the fixed “programme simulation noise” as 
  described in EN 50332-1. 

NOTE 1 Wherever the term acoustic output is used in this 
clause, the 30 s A-weighted equivalent sound pressure level 
L

Aeq,T 

is 

meant. See also Zx.5 and Annex Zx. 

 

All other equipment shall: 

a) protect the user from unintentional acoustic  
  outputs exceeding those mentioned above; and 
b) have a standard acoustic output level not 
  exceeding those mentioned above, and 

  automatically return to an output level not 
  exceeding those mentioned above when the 
  power is switched off; and 

c) provide a means to actively inform the user of the 
  ncreased sound pressure when the equipment is 
  operated with an acoustic output exceeding 
  those mentioned above. Any means used shall 
  be acknowledged by the user before activating a 
  mode of operation which allows for an acoustic 
  output exceeding those mentioned above. The 
  acknowledgement does not need to be repeated 
  more than once every 20 h of cumulative 
  listening time; and 

NOTE 2 Examples of means include visual or audible signals. 
Action from the user is always required. 
NOTE 3 The 20 h listening time is the accumulative listening 
time, independent how often and how long the personal music 
player has been switched off. 

 

d) have a warning as specified in Zx.3; and 
e) not exceed the following: 

  1) equipment provided as a package (player with 
  Its listening device), the acoustic output shall be 
  ≤ 100 dBA measured while playing the fixed 
  “programme simulation noise” described in EN 
 50332-1; 

and 

  2) a personal music player provided with an 
  analogue electrical output socket for a listening 
  device, the electrical output shall be ≤ 150 mV 
  measured as described in EN 50332-2, while 
  playing the fixed “programme simulation noise” 
  described in EN 50332-1.

TRF No. IEC60065K 

For music where the average sound pressure (long 
term L

Aeq,T

) measured over the duration of  the 

song is lower than the average produced by the 
programme simulation noise, the warning does not 
need to be given as long as the average sound 
pressure of the song is below the basic limit of 85 
dBA. In this case T becomes the duration of the 
song. 

 

NOTE 4 Classical music typically has an average sound 
pressure (long term L

Aeq,T

) which is much lower than the average

programme simulation noise. Therefore, if the player is capable 
to analyse the song and compare it with the programme 
simulation noise, the warning does not need to be given as long 
as the average sound pressure of the song is below the basic 
limit of 85 dBA. 

 

For example, if the player is set with the programme simulation 
noise to 85 dBA, but the average music level of the song is only
65 dBA, there is no need to give a warning or ask an 
acknowledgement as long as the average sound level of the 
song is not above the basic limit of 85 dBA.

Zx.3 Warning 
The warning shall be placed on the equipment, or 
on the packaging, or in the instruction manual and 
shall consist of the following: 
−  the symbol of Figure 1 with a minimum height of 
  5 mm; and 
−  the following wording, or similar: 

 

“To prevent possible hearing damage, do not listen 
at high volume levels for long periods.” 

 

 

 

 

 

 

Alternatively, the entire warning may be given 
through the equipment display during use, 
when the user is asked to acknowledge activation 
of the higher level.

Zx.4.1 Wired listening devices with analogue 
input 
With 94 dBA sound pressure output L

Aeq,T

, the input 

voltage of the fixed “programme simulation noise” 
described in EN 50332-2 shall be ≥ 75 mV. 

 

This requirement is applicable in any mode where 
the headphones can operate (active or 
passive), including any available setting (for 
example built-in volume level control). 

 

NOTE The values of 94 dBA – 75 mV correspond with 85dBA – 
27 mV and 100 dBA – 150 mV.

 

 N/A 

With any playing device playing the fixed 
“programme simulation noise” described in 
EN 50332-1 (and respecting the digital interface 
standards, where a digital interface standard 
exists that specifies the equivalent acoustic level), 
the acoustic output L

Aeq,T 

of the listening device 

shall be ≤ 100 dBA. 

 

This requirement is applicable in any mode where 
the headphones can operate, including any 
available setting (for example built-in volume level 
control, additional sound feature like 
equalization, etc.). 

 

NOTE An example of a wired listening device with digital input is 
a USB headphone.

In wireless mode: 
− with any playing and transmitting device playing 
  the fixed programme simulation noise described 
  in EN 50332-1; and 
− respecting the wireless transmission standards, 
  where an air interface standard exists that 

specifies the equivalent acoustic level; and 

− with volume and sound settings in the listening 
  device (for example built-in volume level control, 
  additional sound feature like equalization, etc.) 
  set to the combination of positions that maximize 
  the measured acoustic output for the above-
  mentioned programme simulation noise, the 
  acoustic output L

Aeq,T

Replace the entire subclause in EN 60065:2002 
and EN 60065:2002/A1:2006 by: 
Ionizing radiation 
Apparatus including a potential source of ionizing 
radiation shall be so constructed that personal 
protection against ionizing radiation is provided 
under normal operating conditions and under fault 
conditions. 
Compliance is checked by measurement under the 
following conditions: 
In addition to the normal operating conditions, all 
controls adjustable from the outside BY HAND, by 
any object such as a tool or a coin, and those 
internal adjustments or pre-sets which are not 
locked in a reliable manner, are adjusted so as to 
give maximum radiation whilst maintaining an 
intelligible picture for 1 h, at the end of which the 
measurement is made. 
NOTE 1 Soldered joints and paint lockings are 
examples of adequate locking. 
The dose-rate is determined by means of a 
radiation monitor with an effective area of 10 cm², 
at any point 10 cm from the outer surface of the 
apparatus. 
Moreover, the measurement shall be made under 
fault conditions causing an increase of the high-
voltage, provided an intelligible picture is 
maintained for 1 h, at the end of which the 
measurement is made. 
The dose-rate shall not exceed 1μSv/h (0,1 mR/h) 
taking account of the background level. 
NOTE 2 These values appear in Directive 
96/29/Euratom of 13th May 1996.  
A picture is considered to be intelligible if the 
following conditions are met: 

- a scanning amplitude of at least 70 % of the 

- a minimum luminance of 50 cd/m² with locked 

- not more than one flashover per 5 min.
