We (a uni student club, mostly hiking) own a rope that is practically unknown. We know that it's a year since it was bought (presumably new) and that it has hardly ever been used (no dead hangs, etc). It contains no rating tags/tape outside. We don't know the maker or how much it was bought. Superficially, it's a kernmantle that looks pretty legit.
We've been thinking about whether we should buy a new rope that we KNOW is legit. But because of funding, buying a new rope isn't top of the list. We'd rather determine for certain the legitimacy of the rope (whether legit or not) before making a move.
By luck, we found a strip of plastic hidden underneath the sheath that says "LIFE SAFETY ROPE OF NFPA 1983. 2001 EDITION SET(?) CERTIFIED"
Is this sufficient reason to conclude that the rope is indeed legitimate for aid/rescue use? Can it carry more than 2000 kg as specified by the NFPA 1983?
