This Document provides a test method for determining the roughness of polymer surfaces using contact profilometry (CP).


In microelectronics, the need to accurately determine roughness of polymer surfaces is important when evaluating fluid handling system components from various sources. Rough surfaces have been known to contribute to the shedding of particles, encourage the harboring of micro contamination and promote the proliferation of bacteria. This method can also be used for other applications outside of microelectronics.


The use of CP for measuring the roughness of polymer surfaces is outlined in this Test Method. CP uses a stylus or probe tip that interacts with the surface of interest and moves at a known speed across the surface while recording the up and down movement of the tip relative to the surface, to profile the sample topography.


Values of the scan obtained using this method are reported in Ra and Rq. Refer to ISO 4287 for information about these terms.
