Dentistry - Manual toothbrushes - Resistance of tufted portion to deflection (ISO 22254:2005)

ISO 22254:2005 specifies a test method for determining the resistance of the tufted portion of manual toothbrushes to deflection. This International Standard is applicable to toothbrushes having a conventional flat trim design and may not be applicable to toothbrushes with other designs. The results obtained with this International Standard may not correspond to consumer perceptions of the stiffness of toothbrush bristles.

Zahnheilkunde - Handzahnbürsten - Biegefestigkeit der Besteckungsfläche (ISO 22254:2005)

In dieser Internationalen Norm wird ein Prüfverfahren zur Bestimmung der Biegefestigkeit der Besteckungsfläche von Handzahnbürsten festgelegt. Diese Internationale Norm gilt für Zahnbürsten, die ein konventionelles, planes Design haben und ist für Zahnbürsten mit einem anderen Design unter Umständen nicht anwendbar. Die Ergebnisse, die mit dieser Internationalen Norm erhalten werden, können von den Wahrnehmungen des Verbrauchers bezüglich der Borstenhärte einer Zahnbürste abweichen.

Art dentaire - Brosses à dents manuelles - Résistance à la déflexion de la surface garnie (ISO 22254:2005)

L'ISO 22254:2005 spécifie une méthode d'essai permettant de déterminer la résistance à la déflexion de la surface garnie des brosses à dents manuelles. La présente Norme internationale est applicable aux brosses à dents classiques, à surface garnie plane, et peut ne pas s'appliquer aux brosses à dents d'autres modèles. Les résultats obtenus avec la présente Norme internationale peuvent ne pas correspondre à ce que les consommateurs perçoivent s'agissant de la dureté des filaments de brosse à dents.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 22254 was prepared by Technical Committee ISO/TC 106, Dentistry, Subcommittee SC 7, Oral care
products.
This first edition cancels and replaces ISO 8627:1987.

ISO 22254:2005(E)
Introduction
The stiffness of the tufted area of a manual toothbrush has been of great concern for both consumers and
manufacturers. This International Standard provides a test method for determining the resistance of the tufted
portion to deflection, which could be used to derive a stiffness as described in Annex A. However, this
International Standard does not cover stiffness of manual toothbrushes and its classification. For stiffness
determination, the measurement of the tufted area is required, but the result of the measurement varies over a
wide range depending on the method of the measurement and the shape of the tuft holes. Therefore, the
tufted area and stiffness determinations are described in Annex A. Since the perception of stiffness differs
amongst different countries, stiffness may be classified differently in each country.
