Dentistry - Analysis of Fluoride Concentration in Aqueous Solutions by use of Fluoride-Ion Selective Electrode (ISO 19448:2018)
ISO 19448:2018 specifies test methods for the quantification of fluoride concentrations in dental products including dentifrices, gels, oral rinses, fluoride releasing varnishes, and other fluoride containing products. The methods are based on fluoride ion-selective electrode technology for the analysis of fluoride in aqueous samples derived from dental products.
Zahnheilkunde - Analyse der Fluoridkonzentration in wässrigen Lösungen mit einer fluoridionenselektiven Elektrode (ISO 19448:2018)
Dieses Dokument beschreibt Prüfverfahren zur Quantifizierung von Fluoridkonzentrationen in Dentalprodukten, einschließlich Zahnpasten, Mundspüllösungen und Mundwässern sowie in Lacken, die Fluorid freisetzen und in anderen Produkten, die Fluorid enthalten. Die Verfahren basieren auf der Anwendung einer fluoridionenselektiven Elektrode zur Analyse des Gesamtfluoridgehalts in wässrigen Proben, die von Dentalprodukten genommen wurden.
Médecine bucco-dentaire - Analyse de la concentration en fluorure dans les solutions aqueuses en utilisant une électrode sélective des ions fluorures (ISO 19448:2018)
ISO 19448:2018 spécifie des méthodes d'essai applicables à la quantification des concentrations en fluorure dans les produits dentaires tels que les dentifrices, les gels, les bains de bouche, les vernis fluorurés et d'autres produits contenant du fluorure. Les méthodes reposent sur la technologie de l'électrode sélective des ions fluorures pour l'analyse du fluorure dans des échantillons aqueux prélevés sur des produits dentaires.
Zobozdravstvo - Analiza koncentracije fluorida v vodnih raztopinah z uporabo fluorid-ionske selektivne elektrode (ISO 19448:2018)
Metode za kvantifikacijo koncentracij fluorida v izdelkih za nego zob, vključno z zobnimi pastami, sredstvi za izpiranje ust, premazi, ki sproščajo fluorid, in drugimi izdelki, ki vsebujejo fluorid. Metode temeljijo na tehnologiji fluoridnih ionsko-selektivnih elektrod za analizo fluorida v vodnih vzorcih, odvzetih iz izdelkov za nego zob.

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

Introduction
Fluoride is used in dentistry primarily for caries prevention. Fluoride is the active ingredient for
caries prevention in many dental products such as dentifrices, gels, oral rinses, and fluoride releasing
varnishes. The fluoride concentration in these products is an integral part of other standards where
the product is intended to be analysed for fluoride content. This document provides methods based
on the use of fluoride ion-selective electrod
