I concur, although I have done much work with a true 3D High resolution X-ray system which will give a full model of the features - I used this in my evaluations of CAF growth to "look" at the filaments. It ONLY costs $4K for each sample set up and about another $3K to take the shots----------8-) Nice one Euro - Parliament, but PLEASE don't complain when your cell phone fails when you are calling from the Auto Bahn because the electronics in your eco-friendly car crapped out......... you have implemented legislation that guarantees quality issues with electronics in the short term.

The only way to avaluate this shrinkage fissures is to x-section them--after you do this, you need to make a judgment [great for consultants!?] of whether or not the crack tips provide a stress riser for any operational loading conditions.
