ÖNORM EN 623-4:2005-01

Действует
Advanced technical ceramics - Monolithic ceramics - General and textural properties - Part 4: Determination of surface roughness
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.
Festgelegt sind Bedingungen zur Verwendung von konventionellen Tastschnittgeräten zur Ermittlung der Oberflächenrauheit monolithischer Hochleistungskeramiken sowie die Einstellung der Betriebsparameter der Messeinrichtung. Weiters sind Empfehlungen hinsichtlich bestimmter Vorsichtsmaßnahmen und der Messbedingungen enthalten.
