Coil coated metals - Test methods - Part 20: Foam adhesion

This part of EN 13523 describes a laboratory method for testing foam adhesion to an organic coating on a metallic substrate under dry and wet conditions.

Bandbeschichtete Metalle - Prüfverfahren - Teil 20: Haftfestigkeit von Schaum

Tôles prélaquées - Méthodes d'essai - Partie 20: Adhérence des mousses

La présente partie de l'EN 13523 décrit le mode opératoire de détermination de la résistance à l'adhérence et/ou au marbrage d'un revêtement organique appliqué sur un subjectile métallique.
La pression appliquée sur un rouleau ou une pile de tôles peut affecter la surface du revêtement et provoquer des marques de transfert de brillant, la migration de plastifiant, le changement de couleur, etc., voire un phénomène d'adhérence/de collage.
Les formes plus légères de marbrage sont normalement éliminées par un chauffage modéré (par exemple par exposition au soleil).

1 Scope
This part of EN 13523 describes a laboratory method for testing foam adhesion to an organic coating on a metallic
substrate under dry and wet conditions.

2 Normative references
The following referenced documents are indispensable for the application of this document. For dated references,
only the edition cited applies. For undated references, the latest edition of the referenced document (including any
amendments) applies.

EN 13523-0:2001, Coil coated metals — Test methods — Part 0: General introduction and list of test methods.
3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN 13523-0:2001 apply.
4 Material
4.1 Foam
Organic insulation material obtained by mixing specific components (for example polyol and isocyanate) and
(industrially) applied between two sheets to obtain a sandwich panel.
5 Principle
The foam adhesion is tested by pulling off the foam from the coil coated metal sheet.
The test has only two possible results: “passed” or “failed”.
6 Apparatus
6.1 General
Ordinary laboratory apparatus and glassware, together with the following
6.2 Humidity cabinet
Capable of being maintained at 100 % relative humidity at a temperature of (40 ± 2) °C.
7 Sampling
