Metallic and other non-organic coatings - Review of methods of measurement of thickness (ISO 3882:1986)

Metallische und andere anorganische Schichten - Übersicht von Verfahren der Schichtdickenmessung (ISO 3882:1986)

Diese Internationale Norm fasst die verschiedenen Verfahren, die für die Messung von Schichtdicken verwendet werden, zusammen und beschreibt deren Arbeitsprinzipien. Verfahren zur Schichtdickenmessung können entweder zerstörend oder zerstörungsfrei sein (siehe Tabelle 1). Die in Tabelle 2 und 3 aufgeführten Angaben sollen bei der Auswahl der für einen bestimmten Zweck geeignetsten Verfahren helfen.

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. Esch 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, govern-
mental and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the ISO Council. They are approved in accordance with ISO procedures requiring at
least 75 % approval by the member bodies voting.
International Standard ISO 3882 was prepared by Technical Committee ISO/TC 107,
Metall’ic and other non-organic coatings.
This second edition cancels and replaces the first edition (ISO 3882-1976), table 2 of
which has been technically revised.
Users should note that all International Standards undergo revision from time to time
and that any reference made herein to any other International Standard implies its
latest edition, unless otherwise stated.
