Diese Internationale Norm gilt für Kronen- und Brückenkunststoffe, für die der Hersteller eine Haftung an der metallischen Substruktur ohne makro- mekanische Befestigung, wie Perlen oder Drähte, beansprucht. Sie gilt nicht für Prothesenkunststoffe und ihre Haftfähigkeit an Metall-Legierungen oder an Keramiken und ihre Verbindung mit Legierungen.

NEW!IEC 62271-110:2017 est disponible sous forme de IEC 62271-110:2017 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.
L’IEC 62271-110:2017 est applicable aux appareils de connexion à courant alternatif conçus pour une installation à l'intérieur ou à l'extérieur, et pour fonctionner à des fréquences de 50 Hz à 60 Hz, sur des réseaux de tensions supérieures à 1 000 V, et prévus pour l’établissement et la coupure de courants inductifs. Le présent document est applicable aux appareils de connexion (y compris les disjoncteurs selon l’IEC 62271-100) qui sont utilisés pour l’établissement et la coupure de courants de moteurs à haute tension et de courants de bobines d'inductance shunt, et aussi aux contacteurs à haute tension utilisés pour l’établissement et la coupure de courants de moteurs à haute tension, tels que couverts par l’IEC 62271-106. Cette quatrième édition annule et remplace la troisième édition parue en 2012. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- tous les appareils de connexion sont dorénavant couverts, et non uniquement les disjoncteurs;
- un nombre limité d’essais T10 ne couvrent plus les essais d’établissement et de coupure de courant de bobine d’inductance shunt en dessous de 52 kV;
- l’évaluation et la consignation d’une plage de coupure sans réallumage ont été ajoutées.

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.
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.
Amendment 1 to International Standard ISO 10477:1992 was prepared by
Technical Committee ISO/TC 106, Dentistry, Subcommittee SC 2,
Prosthodontic materials.

Clause 1 Scope
After the first paragraph, add the following paragraph.
"This International Standard applies to polymer-based crown and bridge materials for
which the manufacturer claims adhesion to the metal sub-frame without
macromechanical retention, such as beads or wires. It does not apply to denture base
polymer and its adhesion to metal alloys, or to ceramic and its bonding to alloys."
Clause 2 Normative references
Add the two following references:
Dental casting gold alloys
ISO 1562:1993, .
Dental casting alloys with noble metal content of 25 % up to but
