Ok you must not ride untested wheels by UCI on UCI races.

Bust we saw some prototypes and custom mades on Tour de France, Giro....

How this things go?

Could be custom build equipment used on UCI races?

Ahh that would be the day. I wouldn't be surprised if UCI banned custom wheels entirely..

I wouldn't be surprised if someone produced UCI approval stickers as water-transfer decals. ;)

I am sure Mavic, shimano, camagnolo et.al would not want custom build wheels in UCI races which would be why UCI bans them. Silly really as it was not always this way.

if you're referring to froome's tune wheels in the tour then they don't fall under scrutiny as they're shallow depth.

The way I understand the rules is that you can use whatever you want as long as it doesn't break the following rules:
-rims higher than 2.5 cm
-fewer than 16 spokes
-spoke thicknesses of over 2.4 mm

Anything out of those guidelines need to pass a rupture test and would be listed here:

Explains why Wiggo and Froome were able to use AX-Lightness rims on mountain stages.

Rims higher than 2.5cm? Implying no rims below 2.5 cm in height, I assume.

For the 2014 season it appears that the UCI will remove the "standard" and "non-standard" distinction, and that (presumably) all new production wheels will need whatever new(?) testing is required to get them a UCI sticker?

No, opposite. A "standard" wheel has a rim with more than 16 spokes, a rim height of 25mm or less and the spokes no more than 2.4mm in width.
There is no reference to carbon vs aluminium though.

As a commissaire, it's a crap rule. A local amateur can turn up to race on some home built, 20mm carbon clinchers from china with hardly any spokes but someone who has rebuilt a 24 spoke zipp 440 with a new hub is technically not allowed to race on that wheel, despite it being probably stronger and probably safer.
