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.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

The main task of technical committees is to prepare International Standards. Draft International Standards

adopted by the technical committees are circulated to the member bodies for voting. Publication as an

International Standard requires approval by at least 75 % of the member bodies casting a vote.

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.

Amendment 3 to ISO 8124-1:2012 was prepared by Technical Committee ISO/TC 181, Safety of toys.

b) Cords or chains that can be reasonably expected to form a tangled loop or a noose shall either:

© ISO 2013 – All rights reserved
---------------------- Page: 7 ----------------------
ISO 8124-1:2012/DAM 3

 have a length not exceeding 220 mm (for toys intended for children under 18 months) or have a length

not exceeding 300 mm (for other toys) when measured according to 5.11.2 (length of cords and chains),

 separate into parts with a length not exceeding 220 mm (for toys intended for children under 18 months)

altering the characteristics of the joints (see Figure X4). The length of the separated parts shall be

measured according to 5.11.2 (length of cords and chains).

Toys intended for children of 18 months and over, but under 36 months, and having cords or chains with a

length exceeding 220 mm (which do not separate into one or more parts with a length not exceeding 220 mm)

that can reasonably be expected to form a tangled loop or a noose, shall be accompanied by a warning (see

B.2.22), visible at the point of sale, on the toy itself or on its packaging.
Figure X4 — Example of a joint on cords
c) Fixed loops of cords or chains shall either:

 have a perimeter not exceeding 380 mm when measured according to 5.11.4.2.1 (cords and chains with

a single fixing point or with fixing points less than 94 mm apart), or a distance d not exceeding 96 mm

when measured according to 5.11.4.2.2 (cords and chains fixed to a toy at points of 94 mm or more

apart), or

 separate into parts with a length not exceeding 220 mm (for toys intended for children under 18 months)

or with a length not exceeding 300 mm (for other toys) when tested according to 5.11.3 (breakaway

feature separation test). The length of the separated parts shall be measured according to 5.11.2 (length

of cords and chains).

Toys intended for children 18 months and over, but under 36 months, having a fixed loop that separates into

one or more parts with a length exceeding 220 mm, shall be accompanied by a warning (see B.2.22), visible

at the point of sale, on the toy itself or on its packaging.

Where the distance between fixing points of cords and chains can change during play due to the flexibility of

the toy (e.g. cords on soft filled toys or on textile toys without rigid parts) the perimeter shall be determined

according to 5.11.4.2 regardless of the at-rest distance between the fixing points.

d) The perimeter of nooses:

 shall not exceed 380 mm when measured according to 5.11.4.2. 1 (cords and chains with a single fixing

point or with fixing points less than 94 mm apart), or

 the distance d shall not exceed 96 mm when measured according to 5.11.4.2.2(cords and chains fixed to

the toy at points of 94 mm or more apart).

e) The force of self-retraction mechanisms for cords in toys shall not retract the cord more than 6,4 mm,

under any of the conditions specified when tested according to 5.11.5 (self-retracting cords).

f) Toys with cords and chains intended to be strung across or attached to a cradle, cot or perambulator shall

carry a warning (see B.2.10, B.3.2, B.3.3 and Annex C for guidance). This requirement applies also to

toys with cords and chains intended to be attached to a cradle, cot or perambulator where the cords and

chains of such toys are intended to be out of reach of the children and those cords and chains do not

---------------------- Page: 8 ----------------------
ISO 8124-1:2012/DAM 3

comply with 4.11.1 a) to e). Such toys intended to be strung across a cradle, cot or perambulator will also

need to carry a warning (see B.3.2, B.3.3 and Annex C for guidance).

g) Cords and chains with a free end (i.e. with no attachments) on toys (excluding pull toys) intended for

children under 18 months shall have a free length not exceeding 300 mm when measured according to

5.11.2 (length of cords and chains).

Toys (excluding pull-along toys) intended for children over 18 months of age, but under 36 months of age,

and having cords or chains with a free end and a free length exceeding 300 mm, shall carry a warning

(see B.2.22).

h) Cords and chains with a free end (i.e. with no attachments) on pull toys intended for children under 36

months shall have a free length not exceeding 800 mm when measured according to 5.11.2 (length of

Add the following new sub-clause:
4.31 Yo-yo balls (see E.45)

The initial length l of the yo-yo ball tether, measured as described in 5.37.2 (measurement of initial length)

shall not be greater than 370 mm.

The ratio of the mass m (in grams) to the elastic constant k of the yo-yo ball, measured as described in 5.37.1

(measurement of elastic constant) shall be less than 2,2 (see Equation 1):
m/k< 2,2 (1)
where
m is the total mass of the ball and the tether made of elastic material;
k is the elastic constant of the yo-yo ball as measured in 5.37.1.
Add the following new sub-clause:
4.32 Straps intended to be worn fully or partially around the neck (see E.46)

Toys intended for children under 36 months with straps intended to be worn fully or partially around the neck

and which create a fixed loop shall have a breakaway feature which breaks when tested according to 5.11.3

(breakaway feature separation test).

Safety harnesses, backpack shoulder straps, and the straps of bag/bucket/box handles are excluded.

5 Test methods
5.11.1 Determination of cord thickness

Replace 5.11.1 with the following: Cords cross-sectional dimension (see 4.11.1 a))

Whilst under a tension of (25 ± 2) N, measure the maximum cross-sectional dimension of the cord (see Figure

X5) at between three and five points along its length using an instrument capable of measuring in units of 0,1

mm or less. Determine the average cross-sectional dimension to the nearest 0,1 mm. For cords approaching

1,5 mm in cross-sectional dimension, use a non-compressible measuring device, e.g. an optical projector.

Replace 5.11.2 with the following:

5.11.2 Length of cords, chains and electrical cables (see 4.11.1 b), 4.11.1 c), 4.11.1 g), 4.11.1 h) and

4.11.1 i))

Fix one end of the cord or chain and apply a force of (25 ± 2) N to the other end along the axis of the cord or

chain. Measure, to an accuracy of ± 1 mm, the length of the cord or chain from the fixing point to the end of

the cord or chain. If the fixing point has the same shape or form as the cord or chain, this part is measured as

part of the entire cord or chain (see Figure X6).
