What I do know is that it is a keylock design, and while they recommend sticking to 9.4mm ropes or smaller for Munter hitching I tried it on a 10mm and it seemed to work just fine. There are a lot of applications where you don't need a monster crew-served 'biner, especially if you're not doing rescue work, and despite the hype the Vaporlock is ultralight and nicely sized for general climbing use.

The UIAA equipment standard provides a baseline for equipment performance in a test lab under controlled conditions on new equipment. Although these test conditions are relevant to the conditions encountered climbing, conditions encountered at the crags and the condition of the equipment are equally important. This recommendation from the UIAA member federation The British Mountaineering Council (BMC) provides vital equipment information that is NOT explicitly addressed in the standard, particularly failure modes of the equipment and recommendations for the use, inspection, maintenance, and retirement of equipment.
