In January 2011 BSI published a guide to the measurement and characterisation of surface topography whose principal author was NPL's Prof Richard Leach. We also published an NPL guide on the measurement of rough surfaces using interferometry (relevant to other optical techniques).
BS 1134:2010 Assessment of surface texture
Often the surface of a work piece appears flat and smooth to the human eye. By running a finger across the surface it can feel smooth, but examining this surface under a magnifying device reveals a complex structure, which can be the result of factors such as material structure and paint on the surface, as well as the manufacturing processes to which the surface has been subjected.A product's surface texture often affects its performance, quality and service life. It is critical in machine processing, as in many other disciplines, to evaluate and control the surface characteristics of many products. To control surface texture, it first has to be measured.
