What is involved in correctly inspecting a crimp? I find it hard sometimes to tell the difference between a crimp that's halfway to severing the wire and one that can come adrift at a moment's notice.

But then those are mostly the cheap ones with the plastic rings so you can't really see what's going on inside them.

The inspection is primarily visual, to ensure that the stands are well aligned in the crimp, with no protrusions. And to check there is no damage to the wire due to stripping or a mis-crimp.

For under/over crimping, thats mostly taken care of with the tool calibration. And every shift (work day or X crimps) samples are taken to check the tool is still performing well.

Interesting, so it's mostly in the tool setting! I shall have to see if it is practical to find some way of calibrating my (fairly rubbish!) crimp tool and see if they even keep a setting.

If you have a fish scale, you can see what the retention force is fairly easy. Thats the primary method we use for calibration, albeit with a specific testing hardware.
