Coil coated metals. Test methods -- Film thickness
This part of the ENÂ 13523 series specifies the procedures for determining the dry-film thickness of an organic coating on a metallic substrate (coil coating).
Four appropriate methods are given in this European Standard:
magnetic induction;
eddy current;
micrometer;
optical.
The methods are applicable only to products with smooth and flat substrates but the coating itself may 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 and method d) can provide the minimum, maximum and average thickness.
Non-destructive continuous-web methods on measurement of dry-film thickness (see ENÂ ISOÂ 2808 ) are not dealt with.
