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).
