Advanced technical ceramics - Monolithic ceramics - General and textural properties - Part 1: Determination of the presence of defects by dye penetration

This part of EN 623 specifies qualitative methods for determination of the presence of defects in advanced technical ceramics by dye penetration tests. The results are reported as visual observations of dye penetration.
Three methods are described:
Method A:  A fuchsine dye test which is suitable for white or pale-coloured ceramic products, performed using an evacuation test.
Method B:  A fluorescent dye test which is suitable particularly for those products where the purple fuchsine has insufficient visual contrast with the ceramic material, performed using a proprietary test kit.
Method C:  A fuchsine dye test which is performed by simple immersion in or spraying with a dye solution, suitable for routine testing for major defects.

Dieser Teil von EN 623 legt qualitative Verfahren für die Prüfung auf Anwesenheit von Oberflächenfehlern in
Hochleistungskeramiken mittels Farbstoffeindringtests fest. Die Ergebnisse werden als visuelle
Beobachtungen des Eindringens des Farbstoffes wiedergegeben.
Drei Verfahren werden beschrieben:
Verfahren A: Ein Fuchsinfarbstofftest mit Anwendung der Vakuumtechnik (siehe 5.1), geeignet für weiße oder
schwach gefärbte keramische Erzeugnisse.
Verfahren B: Ein Fluoreszenzfarbstofftest unter Benutzung eines handelsüblichen Testkits (siehe 5.2),
besonders geeignet für die keramischen Erzeugnisse, die nur einen unzureichenden visuellen Kontrast bei
Anwendung des Fuchsinpurpurrots zeigen.
Verfahren C: Ein Fuchsinfarbstofftest mit einfachem Eintauchen in oder Einsprühen mit Farbstoff-lösung
(siehe 5.3), geeignet als Routinetest für größere
