I have some Vero series LEDs from Bridgelux. I want to put multiple LEDs on 1 heatsink. I was planning to use thermal epoxy, so there is the possibility of the aluminium base of the LED touching the metal heatsink.
I have looked through the data sheet and all application notes. I can't see any reference to electrical isolation between the LED power and the heatsink. Is this because it is standard for these type of LEDs to have electrical insulation between the power connection and it's aluminium base?
I have tested with a multimeter and it is open circuit, but I will be driving the LEDs at a much higher voltage than the multimeter is using to do the test.

Although I suspect they don't want you to zap the chip centre with 1kV, I am sure the thermal seat can withstand at least 1kV isolation.
Yes, electrically insulated heatsink surface is standard.
It claims to be somewhat ESD protected but it is not clear to what levels, so avoid large negative voltage and negative discharges to +.
Here's another thermal reference http://www.bridgelux.com/sites/default/files/resource_media/AN31-Handling-and-Assembly-of-Vero-LED-modules.pdf
