Methods of measuring and characterising random rough surfaces have always been of interest in the field of engineering. Measurement and analysis of finer scales of texture of a surface are now mainly effected by the use of a stylus instrument. Because of the finite radius of the tip of the stylus, this instrument cannot sense all the scales of texture on a surface. Evaluation of scales of texture finer than that sensed by the stylus instrument is of interest in many fields of engineering and in the prediction of hysteretic friction and of abrasion of rubber in particular. Two new methods which meet this demand to a great extent are described and their application is illustrated by actual measurements on stone surfaces. A scanning electron microscope is used in one method and an optical microscope in the other. Numerical methods of solution using electronic computers are adopted for the evaluation of texture parameters in both methods. (A) /TRRL/
