Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

ISO 8124-1:2014/FDAM 4:2017(E)

When tested in accordance with 5.25 (Determination of sound pressure levels), toys that are designed

to emit sound shall conform to the following requirements.

a) The A-weighted equivalent sound pressure level, L , of sounds produced by close-to-the-ear toys

pAeq
shall not exceed 65 dB.

b) The A-weighted maximum sound pressure level, L , of toys where the sound is caused as a

pAFmax

result of the movement imparted on the toy by the child (e.g. a toy vehicle with a sound-making

mechanism attached to an axle) shall not exceed 85 dB.

c) The A-weighted equivalent sound pressure level, L , produced by all toys not covered by a) and

pAeq
b) above shall not exceed 85 dB.

d) The C-weighted peak sound pressure level, L , produced by close-to-the-ear toys shall not

pCpeak
exceed 110 dB.

e) The C-weighted peak sound pressure level, L , produced by toys, other than close-to-the-ear

pCpeak

toys and toys using percussion caps or other explosive action, shall not exceed 115 dB.

f) The C-weighted peak sound pressure level, L , produced by toys using percussion caps or

pCpeak
other explosive action shall not exceed 125 dB.

g) If the C-weighted peak sound pressure level, L , produced by toys using percussion caps

pCpeak

or other explosive action exceeds 115 dB, the potential danger to hearing shall be drawn to the

attention of the user. See B.2.19 (Toys which produce high impulse noise).
The requirements in this subclause do not apply to:

— sounds produced by mouth-actuated toys where the sound pressure level is determined by the

blowing action of the child (e.g. whistles and imitation musical instruments, such as trumpets and

flutes);

— sounds such as those produced by xylophones, bells, drums and squeeze toys where the sound

pressure level is determined by the muscular action of the child. This exemption does not apply to

rattles, which are subject to the C-weighted peak requirement in 4.29 e);

— sounds produced by radios, MP3 players, CD players and other similar electronic toys where the

sound output is dependent on the content of removable or re-writeable media such as discs, flash

cards, or internet downloaded content;

— sounds produced by toys that are connected to or interfaced with non-toy external devices, such as

televisions and computers, where the sound pressure level is determined by the external device;

— sound emitted from earphones/headphones;

— sounds produced by toys that reproduce or electronically or mechanically alter the child’s voice,

such as walkie-talkies, recording devices, megaphones and kazoos;

— sounds quantified by A-weighted equivalent sound pressure level, L , produced by pull or push

pAeq

toys as a result of pulling or pushing. This exemption does not apply to sounds quantified by C-

weighted peak sound pressure level, L , from pull or push toys; and
pCpeak

— sounds quantified by A-weighted equivalent sound pressure level, L , produced by percussion

pAeq
caps or other explosive action.

5.25.1 General test conditions
2 © ISO 2017 – All rights reserved
---------------------- Page: 5 ----------------------
ISO 8124-1:2014/FDAM 4:2017(E)
5.25.1.1 General

This subclause contains general test conditions. The specific methods for particular toy categories are

given in 5.25.2 (Specific test methods). If there are differences between the methods specified in this

subclause and those in 5.25.2, the direction given in 5.25.2 shall be followed.

Unless contradicted by this procedure, the measurement procedures in either ISO 11201 or ISO 11202

shall be used.
5.25.1.2 Test environment

An environment that meets the qualification requirements of either ISO 11201 or ISO 11202 shall be used.

If using ISO 11201, the value of the correction factor K shall be ≤ 2.0 dB. If using ISO 11202, the value

of K shall be ≤ 4.0 dB. When ISO 11202:2010 is used, the local environmental correction K shall be

3A 3

calculated using the actual distance between source and microphone, d, and not the minimum distance

of 1 m as stated in Annex A of the document.

NOTE Caution should be used when selecting a testing environment. Typical furnished rooms may not meet

the requirements of the above standards and could cause inaccurate results.

Sound reflections caused by test rigs used for the mounting of toys and/or the operator of the toy shall

be minimized.

No correction needs to be applied to measurements taken where the background noise is 15 dB or more

below the sound being measured. Measurements taken where the background noise is between 15 and

6 dB below the sound being measured shall be corrected by the method contained in ISO 11201 or

equivalent. Environments with a higher background noise shall not be used.
5.25.1.3 Instrumentation

The instrumentation system, including the microphone and cable, shall meet the requirements of a

class 1 instrument as specified in IEC 61672-1. When measuring high peak sound pressure levels, for

example, from toys using percussion caps, the microphone and the entire instrumentation system shall

have the capability of handling linear peak levels exceeding the C-weighted peak levels by at least 10 dB.

5.25.1.4 Microphone positions

Microphone positions are prescribed in 5.25.2 (Specific test methods). They shall all be evaluated with

respect to finding the position with the highest sound pressure level, but complete measurements

are only required for the position yielding the highest level. In practice, this often means that one

microphone is moved from position to position. Whenever it is practicable, it is always an alternative

to rotate the test object instead. Attention shall be paid to maintaining the correct measuring distance.

The sound pressure level shall be measured with the microphone reference direction oriented towards

the dominant sound source. Generally, for free-field response microphones (calibrated for “normal

incidence” to the microphone diaphragm), the axis of the microphone-preamplifier body should be

oriented towards the dominant sound source.
5.25.1.5 Toy operation

Carry out the measurements on a new toy not already subjected to testing. Test battery toys using new

primary batteries or fully charged secondary batteries. Test transformer toys with the transformer

supplied with the toy. If the toy is supplied without a transformer, it shall be tested with the transformer

recommended in the instructions. Normal operating mode(s) shall be reached before the tests are

performed.

Operate the toy under test in that mode of its intended or foreseeable use that produces the highest

sound pressure level to the microphone position, where the maximum sound level is observed. For

toys that have a volume control, the volume shall be set at the maximum level. If the toy has features

that allow it to fit into multiple categories in 5.25.2 (Specific t
