Is the "tension" something standard that goes across all brands, or each brand has it own?
Each brand has it's own. Hannabach 815 medium tension have a total set tension of 41.8 kg. In their standard Pro Arte range D'Addario doesn't do anything as high. Their "extra hard" EJ44 come in at 41.6kg (ok, this difference is negligible ). So if your guitar can stand Hannabach medium, it can stand D'Addario extra hard.
It is a real shame that many brands do not state their tension in an easily accessible form on the website.
