Abstract
A method and a device for determining a topography under load of the surface of a material, wherein a test piece () of the material intended to be determined is subjected to a compression with a determined load between a first and a second clamping surface (), after which, in a compressed state, at least one representation is made of surface portions of the material that are in contact with at least one of said clamping surfaces (), and that the representation is evaluated. The compression is controlled in respect of its speed for obtaining said predetermined load, and said at least one representation is made at a chosen point in time or chosen points in time during this process.
