3.67
emission sound pressure level

sound pressure level at a specified position near a noise source, when the source is in operation under

sound pressure level are denoted L . In other contexts it is also denoted equivalent continuous sound pressure level with

the notation L .

REPLACE THE EXISTING 4.20 WITH THE FOLLOWING
4.20 Acoustics (See A.25)

The requirements in 4.20 do not apply to Personal Music Players supplied with earphones or headphones

which are dealt with in EN 60065:2002/A12 and EN 60950-1:2006/A12 respectively.

For evaluation of exposure from equivalent continuous sound, toys designed to emit sound are divided into

the following 3 sound categories:

Sound category 1: Toys emitting sound during time periods typically longer than 30 s after each initiation by

the child or an adult;

Sound category 2: a) Toys emitting sound during time periods typically shorter than 30 s after each initiation

by the child or by an adult and, b) self-propelled toys. Typical toys in this category are rattles, squeeze toys

and pull-along or push toys

Sound category 3: Toys emitting sound during time periods typically shorter than 5 s after each initiation by

the child or an adult and where each initiation requires such a significant physical effort, or that the toy for

other reasons, is unlikely to be in operation with respect to sound more than about 10 % of the total time of

use of the toy. Typical toys in this category are mouth actuated toys designed to emit sound like whistles and

horns and electronic toy guns.
When in doubt use nearest strictest (=lowest number) category.

For evaluation of exposure from peak sound pressure levels some toys designed to emit sound are allocated

the following sound category:

Sound category 4: Toys designed and actuated in such a way that it is virtually impossible for a person to get

his ear as close as 2,5 cm from the main sound radiating part of the toy. There are very few typical toys in this

category but two of those are toy drums and toy xylophones.

When tested according to 8.28 (determination of emission sound pressure levels), toys which are designed to

emit sound shall conform to the following requirements:

a) The A-weighted emission sound pressure level, L , produced at the specified position at 50 cm by close-

to-the-ear toys shall not exceed 60 dB when measured in a free field.

b) The A-weighted emission sound pressure level, L , produced at the specified position at 50 cm by toys

that can be confused with close-to-the-ear toys shall not exceed 60 dB when measured in a free field.

Such toys weigh typically less than 500 g, and have a shape and construction making it easy to confuse

SIST EN 71-1:2011/oprA2:2012
EN 71-1:2011/prA2:2012 (E)

them with typical close-to-the-ear toys like telephones. They also typically emit sound with duration longer

than 20 s after each initiation.

c) The A-weighted emission sound pressure level, L , produced at the specified position at 50 cm by any

toy shall not exceed 80 dB for sound category 1 toys, 85 dB for sound category 2 toys and 90 dB for

sound category 3 toys.

d) The C-weighted peak emission sound pressure level, L , produced at the specified position at 50 cm

pCpeak

by any toy other than category 4 toys shall not exceed 110 dB. For category 4 toys the limit value is

L = 125 dB.
pCpeak

e) The A-weighted emission sound pressure level, L , produced by toys using headphones or earphones

shall not exceed 85 dB when measured in an ear simulator and corrected to an equivalent free field

sound pressure level.
An overview of the requirements is given in Table X.

emit sound

5) Category 3 toys 90 dB 110 dB
6) Head-/ear-phone toys 85 dB 135 dB
7) Category 4 toys 90 dB 125 dB

NOTE The sound pressure levels in a free field are calculated from measurements in an ear coupler. The sound

pressure levels at 2,5 cm are approximately equal to the sound pressure levels at 50 cm + 25 dB (rounded number,

nominally the difference for a point source is 26 dB).
REPLACE THE EXISTING 8.28 WTIH THE FOLLOWING
8.28 Determination of emission sound pressure levels (See 4.20)
8.28.1 Principle

The principle is to determine the sound pressure level as it would be in an environment excluding all

reflections from walls and ceiling. The operating condition shall be the one yielding the highest A-weighted

equivalent continuous sound pressure level and the highest C-weighted peak sound pressure level

respectively and the microphone position shall be the one out of a specified set of positions yielding the

highest sound pressure level.

8.28.2.1 General

Measure on a new toy. Test battery toys using new primary batteries or fully charged secondary batteries. If a

mains adapter is normally provided by the toy manufacturer, this may be used in place of batteries.

NOTE External power supplies, not supplied by the toy manufacturer, shall not be used as they will, in many cases,

affect the performance of the toy.
8.28.2.2 Test environment

Any environment which meets the qualification requirements of EN ISO 11201 or EN ISO 11202, see figure

XX. Estimate or measure the equivalent sound absorption area in the test room according to Annex A in EN

ISO 3744 or EN ISO 3746. Use figure XX to estimate the environmental correction K or K and make sure

8.28.2.3 Mounting and operating conditions
8.28.3.3.1 General

Test rigs used for the mounting of toys and/or the operator of the toy may cause sound reflections which will

increase the measured level. Minimize such reflections a) by using test rig components (preferably without flat

uncovered surfaces) of dimensions smaller than half a wavelength of the dominant frequencies and/or b) by

making the operator, whenever possible, stand sideways to the reference box.

NOTE It is often convenient to be able to rotate the test object instead of moving the microphone.

Operate the toy in the mode of its intended or foreseeable use which produces the highest sound pressure

level at the microphone position. If the toy is sounding during a shorter time than the measurement time, the

sound shall be repeated as fast as possible considering a sustainable duration during the measurement time.

If needed, the measurement time shall be
