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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use
of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed
patent rights in respect thereof. As of the date of publication of this document, ISO had not received
notice of (a) patent(s) which may be required to implement this document. However, implementers are
cautioned that this may not represent the latest information, which may be obtained from the patent
database available at www.iso.org/patents. ISO shall not be held responsible for identifying any or all
such patent rights.

Introduction
This document is largely based upon existing requirements in ASTM F963, with some modifications to
narrow the scope and facilitate use of the document in multiple jurisdictions.
However, it should not be construed that a toy manufactured in conformity with this document will
be in full compliance with relevant national toy safety requirements in the market where the product
is intended to be distributed. The user of this document is therefore advised to be aware of relevant
national requirements.
Conformity with the requirements of this document will minimize potential hazards associated with
toys due to lack of microbiological cleanliness or inadequate preservation, either of which can result
in illness or injury resulting from use of the toy in its intended play modes (normal use) as well as
unintended play modes (reasonably foreseeable abuse).
This document will not, nor is it intended to, eliminate parental responsibility in the appropriate
selection of toys. Nor will this document eliminate the need for parental supervision in situations where
children of various ages have access to the same toy(s).

INTERNATIONAL STANDARD ISO 8124-12:2023(E)
Safety of toys —
Part 12:
Microbiological safety
1 Scope
This document specifies acceptable criteria for microbiological cleanliness and adequacy of
preservation of the specified toy materials. The requirements in this document apply to all toys that
are, contain or are supplied with aqueous materials (e.g. paste, putty, liquid or gel). In addition, this
document applies to toys that are or include a cosmetic (including those intended for use on a toy as
well as on the child). Powders and similar substances intended to be mixed with water are also within
the scope of this document.
The cleanliness and preservation effectiveness requirements are applicable to a toy as it is initially
received by the consumer in an unopened and undamaged container and do not apply after a toy is
subjected to reasonably foreseeable conditions of normal use and abuse, unless specifically noted
otherwise. The microbial limits and test methods contained in this document are inappropriate to
apply to products that are consumer complaint returns, as there is no way to establish what conditions
the toys have been subject to before being returned.
The following are excluded from the scope of this document:
— materials that are inaccessible during normal use or reasonably foreseeable abuse;
— powder or powder-like materials intended to show biological phenomena, e.g. shrimp eggs, seeds,
soil;
— food.
