Coil coated metals - Test methods - Part 24: Resistance to blocking and pressure marking
This Part of EN 13523 describes the procedure for determining the resistance to blocking and/or pressure marking of an organic coating on a metallic substrate.
Pressure generated within a coil or a stack of sheets can affect the coating surface and cause marks of gloss transfer, plasticizer migration, colour change, etc. and even blocking/sticking.
Lighter forms of pressure marking are normally removed by gentle heat (e.g. sunshine).

Tôles prélaquées - Méthodes d'essai - Partie 24 : Résistance à l'adhérence et au marbrage
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).
