Oooooh - haven`t you all been busy?
If I may inject my thoughts on this?
(First off - my first job was with FKI Babcock, doing QA; one of the jobs was testing the crimp connections used on the fork lift contactors for breaking strain, so I DO have a bit of experience in that dept. OK? )
`Pache: Given the lack of a specific piece of kit, I don`t think it was a bad experiment - as said, no-one else thought of it! My negative points with it are as follows:
1. As previously stated, 2.5 should be a blue crimp, not a red one.
2. Also previously, the strain was along the axis of the crimp, but perpendicular to the axis of the pushfit, therefore biasing the result significantly.
3. I used to have a pair of crimp pliers similar to those in the link. IMHO they weren`t "fit for purpose", as the jaws are completely smooth. IIRC, Admin posted a pic of the SWA ones, which have shaped dies.
I believe, if the experiment were to be repeated, with the strain on the axis of the connection, on both connectors, and the crimp made off with a "decent" crimp pliers, the result may be far more interesting.
n.b. FYI: in order to test joints like this, the piece of kit used is similar to a tool thread on a lathe, which carries a set of jaws away from a fixed point, up a thread. This provides a consistent & constant torque & strain, with no sudden jerks or pulls.
As far as any sort of electrical test on the connections after failure -???????
If the connector has failed, you won`t have a circuit to test, will you? Or have I missed a point.
Larnaca: I believe you do have a good knowledge of your subject. However, I also believe your comments regarding Apache were out of order somewhat. I`d second snakehips` comments about employing him - I`d take him on, anytime
