We always called it 550 cord.
there was also a breaking strength for the individual threads inside.
Can not recall what it was ...we used it rigging static line parachute rigs. 80-100 lbs? perhaps less. Long time ago.
Unfortunately there are a lot of products on the market that call themselves parachute cord. While they look like it they are not.
I also recall the parachutes we started jumping with were made by ( I kid not ) the CHEEPO Parachute Co. - a real convidence builder. "OK Who's first?" "crickets."
