WARNING This is how my rims behaved, your rims may behave differently.
I had a pile of broken/worn Mavic rims in my garage. Then I was advised an Iwanson gauge can be used to measure the wear.

Using the gauge I measured the rims and found-
Measured using a Iwanson Gauge Spring Measuring Calliper
Rim type (all Mavic) Condition Measurement (mm)
1 XC717........New (unused)................1.6
2 XC719................worn.....................1.3
3 XC719................worn....................1.0 to 1.2
4 XC719................worn.....................1.0 to 1.3
5 Mavic.................worn......................0.8 to 1.0
6 XC719................worn......................1.0
7 XC717................worn......................0.7 to 1.0
8 XC519................worn......................0.6 to 1.0
9 Mavic.................worn......................0.6 to 1.0
10 XC317...............broken...................0.7 to 0.9
11 Mavic................broken...................0.7
All the worn rims had been discarded as they looked past it.
Conclusion
Wear is never even, side to side variation and uneven wear on one side occurs.
Rims break at 0.7mm
Replace rim at 0.9 to 1.0mm
Warning- other manufacturers rims may behave differently!
I would be interested to hear others thoughts on this important matter!
