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.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

Introduction
This document is largely based upon existing requirements in the United States of America toy safety
standard, ASTM F963, with some modifications to narrow the scope and facilitate use of the standard
in multiple jurisdictions.
However, it should not be construed that a toy manufactured in compliance 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.
Compliance with the requirements of this document will minimize potential hazards associated with
toys resulting from their use in their 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. In addition, this document will not eliminate the need for parental supervision
in situations where children of various ages may have access to the same toy(s).

DRAFT INTERNATIONAL STANDARD ISO/DIS 8124-12:2022(E)
Safety of toys —
Part 12:
Microbiological Safety
1 Scope
The requirements in this document apply to all products that are or contain materials which are
aqueous in nature, supplied as or with a toy or that are or include a cosmetic (including those intended
for use on a toy as well as on the child), paste, putty, powder, liquid, or gel that is aqueous in nature.
Powders and similar substances intended to be mixed with water by the child are also in scope for
microbiological cleanliness and are to be tested before and after mixing; such items are in scope for
microbiological challenge only if they are intended for repeated use and will be stored between play
sessions (manufacturers should consider the potential effect of variations in mixing proportions). 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 standard are inappropriate to apply to products
that are consumer complaint returns, as there is no way to establish what conditions the toys may have
been subject to before being returned. Toys in which the aqueous materials are contained so that there
is no accessibility either before or after use-and-abuse testing are exempt from these requirements.
The requirements of this document specify acceptable criteria for microbiological cleanliness and
adequacy of preservation of toy materials within the scope.
