Coil coated metals - Test methods - Part 21: Evaluation of outdoor exposed panels

Coil coated metals - Test methods - Part 21: Evaluation of outdoor exposed panels

This part of the EN 13523 series specifies the procedure for evaluating the behaviour of an organic coating on a metallic substrate during and after outdoor exposure. Panel design, preparation and the procedure for outdoor exposure are performed in accordance with EN 13523 19.
After washing of the panel, some dirt can remain on the panel. This remaining dirt can influence the accuracy and precision of readings of gloss and colour, performed on exposed panels, although carried out in accordance with the standards. Unlike other precise measurements, the objective of this European Standard is to report on trends in the corrosion and/or paint degradation behaviour of coil coated panels.

Bandbeschichtete Metalle - Prüfverfahren - Teil 21: Bewertung von freibewitterten Probenplatten

Tôles prélaquées - Méthodes d'essai - Partie 21 : Évaluation des panneaux exposés en extérieur

Le présent document spécifie le mode opératoire à appliquer pour évaluer le comportement d’un revêtement organique sur un subjectile métallique durant et après exposition en extérieur. La conception des panneaux, la préparation et le mode opératoire pour l’exposition en extérieur sont à réaliser conformément à l’EN 13523 19.
Après lavage du panneau, il est possible que de la saleté reste sur le panneau. La saleté résiduelle peut influer sur la précision et la fidélité des lectures du brillant et de la couleur réalisées sur les panneaux exposés, même si celles-ci sont effectuées conformément aux normes. Contrairement à d’autres mesures fidèles, le but de la présente Norme européenne est de rendre compte des tendances observées concernant le comportement à la corrosion et/ou à la dégradation de la peinture des panneaux prélaqués.

Coil coated metals - Test methods - Part 12: Resistance to scratching
oSIST prEN 13523-12:2023

This document specifies the procedure for determining the resistance of an organic coating on a metallic substrate to penetration by scratching with a needle.
It is possible that with some aluminium alloys and thin gauge steel substrate below 0,4 mm, that rather than scratching, the needle will deform the substrate. Under these conditions, this test method is not applicable.
Soft coatings such as poly vinyl chloride (PVC) and structured coatings will not give a precise result due to the soft nature of the coating and/or the potential for the needle to snag.
The method is not applicable to conductive coatings.

Coil coated metals - Test methods - Part 1: Film thickness
oSIST prEN 13523-1:2023

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).

Coil coated metals - Test methods - Part 22: Colour difference - Visual comparison
oSIST prEN 13523-22:2023

This document specifies the procedure for determining the difference in the colour of an organic coating on a metallic substrate by visual comparison against a standard using either diffuse natural daylight or artificial daylight in a standard booth.
NOTE   Results can differ between natural and artificial daylight.
It might be that two colour specimens will match in daylight but not under another light source. This phenomenon is known as metamerism (see EN 13523 3).
If a metameric match is to be reported in objective terms, spectrophotometric measurements (using CIE Standard Illuminants D65 and A) can be made, in accordance with EN 13523 3.
No statement is made about either the precision or the accuracy of this procedure since the results derived are neither in numerical form nor do they provide a pass/fail evaluation in objective terms. Therefore, this procedure is only intended to be used where the use of colour measuring instruments is not recommendable (evaluation of colour matches, inspection of metallic colours, etc.).
The standardization of such visual comparisons, by light sources, illuminating and viewing geometry and specimen size, provides for improved uniformity of results. This practice is essential for critical colour matching and is highly recommended for colour inspections.

Coil coated metals - Test methods - Part 3: Colour difference and metamerism - Instrumental comparison
oSIST prEN 13523-3:2023

This document specifies procedures for determining the instrumental colour difference (CIELAB   or  ) of an organic coating on a metallic substrate compared to another one used as a reference (usually called reference) and the metamerism depending on the illuminant.
When two colour specimens have identical spectral reflectance curves, they are matching under any illuminant irrespective of its spectral characteristics. This is termed a “spectral match”. It is also possible for two colour specimens having different spectral reflectance curves to match visually under a given light source but not to match under another light source with different spectral characteristics; such matches are termed "metameric".
One quantitative description of metamerism is the so-called "metamerism index".
Information on the metamerism index is of limited value where ΔE (instrumental colour difference for a given illuminant) is > 0,5. The metamerism index is not suited for determining the absolute colour difference or colour consistency of a given specimen at change of illuminant.
The colour difference under the reference illuminant is to be measured in colour coordinates L*, a* and b*.
Excluded from this method are organic coatings producing fluorescence and/or which are multicoloured, pearlescent or metallic.
Establishing a reference as well as the magnitude of an acceptable colour difference are not covered by this method.
Two methods are given in this document:
a)   instrumental colour difference measurement using a tristimulus colourimeter;
b)   instrumental colour difference measurement using a spectrophotometer or equivalent.
It is advised that care is taken when measuring e.g.
-   textured surfaces;
-   fluorescent coatings;
-   metameric coatings;
-   multi-coloured, pearlescent, metallic or special colour effect coatings.

Coil coated metals - Test methods - Part 10: Resistance to fluorescent UV radiation and water condensation
oSIST prEN 13523-10:2023

This part of the EN 13523 series specifies the basic principles and procedure for determining the resistance of an organic coating on a metallic substrate (coil coating) to a combination of fluorescent UV radiation, and water condensation and temperature under controlled conditions.
Due to varied conditions which occur during natural weathering and the extreme nature of accelerated testing, correlation between the two cannot be expected.
Not all organic coatings will perform on an equal basis but a degree of correlation between the same generic type might be observed.

Coil coated metals - Test methods - Part 14: Chalking (Helmen method)
SIST EN 13523-14:2023

This document describes the procedure for determining objectively the chalking resulting from natural or artificial weathering of an organic coating on a metallic substrate.
The advantage of this procedure for measuring chalking of an organic coating is that the result can be read off immediately on an instrument. Subjective judgement by visual comparison of test specimens with reference specimens is not necessary.
Reproducible results can only be obtained by careful execution of the test. Special attention is paid to the adhesive tape and its application to the test surface.
The test method is not applicable to embossed coatings. In the case of textured coatings, the degree of texture will influence readings. Also, dirt collection can influence readings on outdoor weathered specimens.
NOTE   Different methods for assessing chalking are in use. The results of these different methods are not comparable.
