Coil coated metals - Test methods - Part 1: Film thickness
This document specifies the procedures for determining the dry-film thickness of an organic coating on a metallic substrate (coil coating).
Five appropriate methods are given in this document:
a) magnetic induction;
b) eddy current;
c) micrometer;
d) optical;
e) ruggedized optical interference.
The methods are applicable only to products with smooth and flat substrates, but the coating itself can be textured. In that case, for methods a) and b), the average of a series of readings will represent an average of the thickness of the organic coating, while method c) will give the maximum thickness, method d) can provide the minimum, maximum and average thickness, and e) will give the total thickness.
Non-destructive continuous-web methods on measurement of dry-film thickness are only applicable on method a).
Bandbeschichtete Metalle - Prüfverfahren - Teil 1: Schichtdicke
Dieses Dokument legt die Verfahren zum Bestimmen der Trockenschichtdicke einer organischen Beschichtung auf einem metallischen Substrat (Bandbeschichtung) fest.
Fünf geeignete Verfahren werden in diesem Dokument angegeben:
a) Magnetoinduktion;
b) Wirbelstrom;
c) Messschraube;
d) optisch;
e) robuste optische Interferenz.
Die Verfahren sind nur auf Produkte mit glatten und ebenen Substraten anwendbar, die Beschichtung selbst kann aber strukturiert sein. In diesem Fall stellt bei den Verfahren a) und b) der Mittelwert einer Reihe von Messungen einen Durchschnittswert der Dicke der organischen Beschichtung dar, während Verfahren c) die größte Schichtdicke ergibt, mit Verfahren d) die kleinste, größte und durchschnittliche Schichtdicke ermittelt werden kann und Verfahren e) die Gesamtdicke ergibt.
Nicht zerstörende Verfahren zum Messen der Trockenschichtdicke für Endlosbahnen sind nur bei Verfahren a) anwendbar.
Tôles prélaquées - Méthodes d’essai - Partie 1 : Épaisseur du feuil
Le présent document spécifie les méthodes de détermination de l’épaisseur de feuil sec d’un revêtement organique sur un subjectile métallique (prélaquage en bandes continues).
Cinq méthodes adaptées sont décrites dans le présent document :
a) induction magnétique ;
b) courants de Foucault ;
c) micromètre ;
d) optique ;
e) interférences optiques renforcées (ROI).
Ces méthodes s’appliquent seulement aux produits qui comprennent des subjectiles lisses et plats, le revêtement lui même pouvant être texturé. Dans ce cas, pour les méthodes a) et b), la moyenne d’une série de lectures représentera une moyenne de l’épaisseur du revêtement organique, tandis que la méthode c) donnera l’épaisseur maximale, que la méthode d) peut fournir les épaisseurs minimales, maximales et moyennes, et que la technique e) fournira l’épaisseur totale.
Les méthodes non destructives sur toiles continues visant à déterminer l’épaisseur de feuil sec s’appliquent uniquement à la méthode a).
Prevlečene kovine, ki se navijajo - Preskusne metode - 1. del: Debelina premaza
Ta del skupine standardov EN 13523 določa postopke za ugotavljanje debeline suhega premaza organske prevleke na kovinski podlagi (prevlečene kovine, ki se navijajo).
V tem evropskem standardu so podane štiri ustrezne metode.
a) magnetna indukcija;
b) vrtinčni tok;
c) mikrometer;
d) optična metoda.
Metode se uporabljajo samo za proizvode z gladko in ravno podlago, medtem ko je lahko prevleka teksturirana. V tem primeru bo za metodi a) in b) povprečje niza odčitkov odražalo povprečno debelino organske prevleke, metoda c) bo podala največjo debelino, metoda d) pa bo podala najmanjšo, največjo in povprečno debelino.
Ta dokument ne obravnava neporušitvenih metod z neprekinjeno mrežo za merjenje debeline suhega premaza (glej standard EN ISO 2808).

film thickness
distance between the surface of the film and the surface of the substrate
[SOURCE: EN ISO 2808:2019, 3.1]
4 Principle
4.1 Method A: Measurement on magnetic substrate – magnetic induction
The film thickness on a magnetic substrate is determined by means of an electromagnetic probe placed
on the coating and developing an electromagnetic field. The variation of this field is a function of the
distance between the probe and the substrate. This signal is measured and converted to the film thickness
reading.
4.2 Method B: Measurement on a non-magnetic substrate – eddy current
The film thickness on a non-magnetic conductive substrate is determined by means of an electromagnetic
probe placed on the coating and generating eddy currents in the substrate. The magnitude of the eddy
currents is a function of the distance between the probe and the substrate. This measuring signal is
derived from the impedance change in the probe and converted to the film thickness reading.
4.3 Method C: Measurement on all substrates – micrometer method
The film thickness is determined by measuring the coated sample and then removing the organic coating
and re-measuring the sample minus the coating or by measuring a film of organic coating that has been
removed from the sample.
4.4 Method D: Measurement on all substrates – optical method
The film thickness is determined by microscopical measurement of a section cut through the film. The
defined cut may be made in the coating using a special blade (symmetrical cut), a special paint borer
(conical bore) or a milling tool (sloping cut).
4.5 Method E: Measurement on all substrates – ruggedized optical interference (ROI)
The film thickness on a non-magnetic conductive substrate is determined by means of non-contact, ROI
technology which measures multi-layer coatings and thin film thicknesses down to sub-micron levels.
5 Apparatus and materials
5.1 Instruments for measuring film thickness, using the principles described in Clause 4.
5.2 Solvent, suitable for removing organic coatings, for example methyl ethyl ketone (2-butanone).
5.3 Suitable abrasive and/or blunt knife or other means of removing softened organic coatings that
do not damage the substrate.
5.4 Cutting tool, for Method D.
