Enchanting + Destruction magic?

Ok so earlier today i had nothing to do and started looking through all the perks for stealth, worriers, mages; anyway i was looking for anything that i had overlooked before, and low and behold i saw a perk in destruction that sais "shock" damage will decintegrate your enemy at 15% health. since it doesn't say shock "spells" does that mean i can enchant a weapon with shock damage and still use the effect? or has someone atempted already?_ because i only have about 20 destruction it will take a while to get to 70; could a decent destruction mage try this out for me and tell me how it worked?

I tested this with a sword with shock dmg and it didn't seem to work on any of the different targets I tried. The perks says 15% health but even with Thunderbold it only disintegrates on rare occasions, I need Lightning Storm to have a guaranteed disintegrate. Possible it works on some targets, but none of the 15 types I tried on.
