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 www .iso
.org/iso/foreword .html.
This document was prepared by Technical Committee ISO/TC 106, Dentistry, Subcommittee SC 7, Oral
care products.
This second edition cancels and replaces the first edition (ISO 28158:2010), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— inclusion of the alternative test method for the strength of the products using a tensile test equipment
(e.g. push-pull force gauge, tensile testing equipment or equivalent);
— addition of the requirement that having no displacement which is more than 10 mm of the loading
point in the direction of the loading at the force of 10 N;
— addition of the directions for procedure of tooth cleaning using the integrated dental floss and
handles, if necessary, and a recommendation on safety information recommending the user to apply
a gentle “sawing” or “zig-zag” motion of the floss during insertion into and removal of the floss from
the area between teeth to reduce possible injury to the interdental gingiva potentially caused by the
floss snapping forcefully into the soft gingival tissue.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www .iso .org/members .html.

is subsequently added.
This document excludes specific qualitative and quantitative test methods for demonstrating freedom
from unacceptable biological risks. For assessment of such biological risks, see ISO 10993-1 and ISO 7405.
