5.31 Tension test for magnets
0 p9 j; |/ G4 k1 u1 @2 _See 4.30.2 c).
+ B# O0 ?1 A) M$ _5 \5.31.1 Principle
These tests simulate the intended or reasonably foreseeable play pattern. It is recognized that toys may
6 g; e7 O3 I$ g3 H2 Bcontain a single magnet or a combination of magnets, magnetic components and/or metal mating parts and
the tests are designed to simulate a reasonably foreseeable play pattern using these components to attach
/ }' e3 G9 Y; p* a+ Qand detach the magnetic parts.
For toys that contain more than one magnet/ magnetic component, the test specified in 5.31.2 (toys with
magnet(s) or magnetic component(s)) shall be carried out unless it is not possible to perform the test without
damaging the toy. In the latter case, the test shall be carried out using the reference disk, as described in
5.31.4 (toys that contain one magnet only and no mating metal component).
NOTE: An example of a case where it is not possible to perform the test in 5.31.2 with magnet(s) or magnetic
component(s) without damaging the toy, is a toy figurine with one accessible but non-graspable magnet in each foot.
# o, S4 `3 ?, q+ q- t$ BToys that contain one magnet only and a mating metal component shall be tested according to 5.31.3 (toys

Toys that contain one magnet only and no mating metal component, shall be tested according to 5.31.4 (toys
) O0 X' j& H0 S! W8 s) wthat contain one magnet only and no mating metal component), since this simulates a play pattern where the
toy is attached and detached to a surface that is not delivered with the toy.

( e! K. s2 n) l' ~0 _3 hE.44 Magnets
See 4.30.
7 f9 Y* h$ w3 {+ aThese requirements are intended to address the hazards associated with ingestion of strong magnets (e.g.
) X; M+ A0 H$ B2 uneodymium iron boron type magnets (“NIB”)), that are capable of causing intestinal perforation or blockage.
! [) V8 l- V3 VThese hazards are additional to those associated with small parts such as suffocation or asphyxiation (see
E.6). These requirements apply regardless of the age of the intended user.
/ u8 W) v2 v6 @Magnets found by children can be ingested. If more than one magnet, or one magnet and a ferromagnetic
object (for example an iron or nickel object) is ingested, the objects can attract each other across intestinal
8 t: q1 B. M+ q9 r9 l! @1 s' Iwalls and cause perforation or blockage, which can cause severe injuries that may be fatal.
. K  ], n' W! V* y8 W* z6 ]) s2 D% GMultiple incidents, including at least one fatality, have been reported involving ingestion of magnets resulting
5 f4 b4 Y" C; i& l: oin perforation or blockage of the intestines. These incidents have involved children younger and older than 3
3 m, W4 N1 E/ F0 pyears of age. Medical signs associated with intestinal perforation or blockage can easily be misinterpreted
; V! y4 _: ]9 F$ Y8 o3 L, Rsince many children exhibit only flu-like symptoms. Such misinterpretations have caused delays in the medical
treatment and led to serious consequences for children.
4 ~5 r1 D, C9 C6 E% ~For the purpose of this standard, magnets or magnetic components that could be ingested are identified using
the small parts cylinder. The small parts cylinder was originally designed to identify small parts in toys
: Q* n& Y$ N6 }" fintended for children under 3 years of age, which are capable of causing suffocation or asphyxiation. It was
! S$ w+ i/ }2 J9 Y# G" k: mnot designed for identifying objects that can be ingested by older children. The decision to use the small parts
cylinder also for assessment of magnets or magnetic components that can be ingested was made for practical
reasons: The cylinder is a well known test template and it provides a safety margin since the magnets and
  b" X1 P$ b2 ~( G2 h$ hmagnetic components that have been involved in incidents all fit into the cylinder with a large margin. This
same principle has been applied in the requirements for expanding materials.
6 J  A% Z$ K) BThe risk of magnets attracting each other across intestinal walls is a function of magnet strength. A limit value
in the form of a magnetic flux index has been introduced to define what a sufficiently weak magnet is. Analysis
