July Issue:: Forum introduction
This Month's Introduction
As usual, this month's issue will focus on our discussion theme.
If you are interested in other nondestructive testing topics, don't
hesitate to discuss them in this forum as well.
You may have noticed the new forum name "NDT.net Forum",
expanding the former UTonline forum to include the complete range of
NDT methods. If the discussion gets too crowded (we hope!) we'll open
more Forums for each NDT topic - obviously ultrasonic testing
as one of the major NDT methods would the first!
The NDT community, especially in Germany, was shocked by the train
accident in Eschede on June 3, 1998. It was all too clear that NDT
techniques had not been applied effectively. The theme is so important
that we continue our focus on Railway Testing - learning from failure!
Another big part of this issue highlighting
"The Reliability of NDT techniques and procedure of validation".
Last but not least we are pleased to present many other papers in this
issue - please access those via the front page.
Thanks to all participants for shearing their ideas with this forum!
We have provided the following updates:

Almost all the July issue is online,
but some updates or corrections may still proceed (we need a break),
better you'll wait with save to disk!
