適用范圍：This part of EN 623 concerns the use of conventional stylus type instruments for the measurement of surface texture of advanced monolithic technical ceramics, sets the test machine measuring parameters, and recommends the adoption of certain precautions and conditions of measurement. NOTE Non-contact optical methods of surface texture measurement employ a different concept using a narrow laser beam. The interaction of the beam with the surface is influenced by the angle of the surface to the beam and the reflectivity/translucence of the surface. The reflected beam is detected in a number of ways based on spot focus or beam deflection and converted into a height profile. Results from such a test are not directly equivalent to those obtained by the stylus method.
