BS EN 623-1:2006 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.
