This part of the European Standard specifies the conditions for the determination of the diameter and cross-section
area of ceramic single filament, as used in fibre reinforcement of ceramic composites for three methods.
NOTE The cross-sectional area of filaments from different suppliers will vary significantly. The term diameter applies both
to circular cross-section (true diameter) and non-circular cross-sections (apparent diameter).
Diese ÖNORM legt drei Verfahren zur Bestimmung von Durchmesser und Querschnittsfläche von keramischen Einzelfasern, wie sie bei der Faserverstärkung von Keramik verwendet werden, fest.
