Safety of toys —Part 1:
Safety aspects related to mechanical and physical properties
1 Scope
The requirements in this part of the Toy Safety Standard (hereinafter referred to as “STStandard”) apply to all toys, i.e. any product or material designed or clearly intended for use inplay by children under 14 years of age.
They are applicable to a toy as it is initially received by the consumer and, in addition, they
apply after a toy is subjected to reasonably foreseeable conditions of normal use and abuse
unless specifically noted otherwise.
The requirements of this part of ST Standard specify acceptable criteria for structuralcharacteristics of toys, such as shape, size, contour, spacing (e.g. rattles, small parts, sharp
points and edges, and hinge-line clearances) as well as acceptable criteria for properties
peculiar to certain categories of toy (e.g. maximum kinetic energy values for non-resilient-tipped
projectiles and minimum tip angles for certain ride-on toys).
This part of ST Standard specifies requirements and test methods for toys intended for use bychildren in various age groups from birth to 14 years of age. The requirements vary according to
the age group for which a particular toy is intended. The requirements for a particular age groupreflect the nature of the hazards and the expected mental and/or physical abilities of a child tocope with them.
This part of ST Standard does not purport to cover or include every conceivable potential
hazard of a particular toy or toy category.
This part of ST Standard has no requirements for those characteristics of toys which represent
an inherent and recognized hazard which is integral to the function of the toy.
EXAMPLE: An example of such a hazard is the sharp point necessary for the proper functionof a needle. The needle is a hazard which is well understood by the purchaser of a toy
sewing kit, and the functional sharp-point hazard is communicated to the user as part of thenormal educational process of learning to sew as well as at the point of purchase by meansof cautionary labelling on the product's packaging.
The requirements of this standard do not release parents or the persons in charge of caring
for a child from their responsibility of watching over the child while he or she is playing.
The requirements of this standard aim at reducing as far as possible the hazards considered
to be commonly posed by toys (e.g. hazards caused by toy materials, hazards specific tochildren of the intended age group, or hazards specific to characteristics of different kinds oftoys).
Most toys are likely to avoid causing accidents by conforming to this Standard.

3 Terms and definitions (Non-alphabetical order)
For the purposes of this document, the following terms and definitions apply.
3.1

toy
any product or material designed or clearly intended for use in play by children under 14
years of age

3.2

normal use
play modes that conform to the instructions which accompany the toy, and which have been
established by tradition or custom, or which are evident from an examination of the toy

3.3

reasonably foreseeable abuse
use of a toy under conditions or for purposes not intended by the supplier, but which canhappen, induced by the toy in combination with, or as a result of, common behaviour in achild
EXAMPLE: Deliberate disassembly, dropping or use of a toy for a purpose for which it was
not intended.
NOTE: Tests simulating reasonably foreseeable abuse are given in 5.24.

(2) A toy with stuffing materials comprised of small parts or with soft-fillings (e.g. plastic foam)from which pieces can be bitten or torn thereby producing small parts, which fit entirely inthe cylinder when tested according to 4.4 (small parts), shall have at least one covering sothat, after being tested according to 5.22.6.2 (Tension test for seams in soft-filled (stuffed)
toys and beanbag-type toys), it shall not be possible to insert the front part of probe A, as
specified in 5.7 (Accessibility of a part or component) , through any one opening in the seamor cover material.
4.3.4

Glass and pottery(1) Accessible glass and pottery may not be used for toys intended for children under 3 yearsof age(2) Glass may be used for toys intended for children of 3 years of age and over where;① Its use is necessary to the function of the toys (for example, glass slides in an opticaltoy);② Small glass vessels are included in scientific kits and scale models. Where such
vessels are intended to be exposed to heat, only borosilicate glass shall be used;③ Solid glass marbles, solid glass eyes for dolls.
4.4 Small parts
4.4.1 For children under 36 months
Toys intended for children under 36 months, removable components thereof andcomponents liberated during testing in accordance with 5.22 (reasonably foreseeable abusetests) shall not fit entirely, whatever their orientation, into the small parts cylinder when tested
in accordance with 5.2 (small parts test).
The requirement also applies to fragments of toys, including, but not limited to, pieces offlash, slivers of plastics and pieces of foam or shavings.
The following are exempted before and after subjecting the toy to the tests according toClause 5:
paper books and other articles made of paper and pieces of paper;

yarn;elastic and string;
4.4.2

For children 36 months and overToys and toys containing removable components, intended for children 36 months and over,which fit entirely in the small parts cylinder when tested in accordance with 5.2, shall carry awarning (see 7.2.4.1 for guidance).
