Critical bonus range vs melee

When items say "1% Critical Chance" and leave it at that, how do I know
if the bonus applies to melee, range, or both? Examples include
Shadowskin Gloves with 1% Crit bonus. On the same vein, what about
attack power? I remember way back when I used quest reward from raptor
quest line in Wetlands with attack bonus against beasts. I could have
sworn that removing the armor drop my range damage output noticably
against beasts. But these are just casual observations. Anybody did the
test on the subject?
