Vitreous and porcelain enamels - Terminology - Part 1: Terms and definitions (ISO 19496-1:2017)
ISO 19496-1:2017 defines a number of terms relating to vitreous and porcelain enamels and their technology. This list is not complete and only comprises those terms for which the definition is considered necessary for correct and adequate understanding in order to clarify these processes.
The interpretations given are those corresponding to the practical usage in this field and they do not necessarily coincide with those used in other fields.
For purposes of clarification, the term "vitreous enamel", used throughout this document, is synonymous with "porcelain enamel", the term favoured in the United States and some other countries.

Dieses Dokument definiert eine Reihe von Begriffen, die Emails und Emaillierungen sowie zugehörige Technologien betreffen. Die Auflistung der Begriffe ist nicht vollständig und umfasst nur die Begriffe, deren Definition für ein richtiges und ausreichendes Verständnis als notwendig erachtet wird, um die betreffenden Prozesse zu erläutern.
Die angeführten Erläuterungen sind praxisnah für das Gebiet der Emails und Emaillierungen und entsprechen nicht zwangsläufig denen, die auf anderen Gebieten verwendet werden.
Zur besseren Übersichtlichkeit steht der englischsprachige Begriff "vitreous enamel", der in diesem (englisch¬sprachigen) Dokument durchgängig verwendet wird, gleichbedeutend für den in den Vereinigten Staaten und einigen anderen Ländern bevorzugt verwendeten Begriff "porcelain enamel".
Emaux vitrifiés - Terminologie - Partie 1: Termes et définitions (ISO 19496-1:2017)
ISO 19496-1:2017 définit un certain nombre de termes relatifs aux émaux vitrifiés et à leur technologie. La liste n'est pas exhaustive et ne comprend que les termes dont la définition est considérée comme nécessaire à la bonne compréhension, afin de clarifier ces processus.
Les interprétations données sont celles qui correspondent à l'usage pratique dans ce domaine, et qu'elles ne coïncident pas nécessairement avec celles d'autres domaines.
À titre de clarification, le terme anglais «vitreous enamel», utilisé dans tout le présent document, est synonyme du terme anglais «porcelain enamel», qui est le terme usité aux États-Unis et dans certains pays.

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.
