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.

This is a brilliant idea which has been carried out to perfection by Edelrid. Carrying a couple of these as quickdraw sets when sport climbing will save wear on your rope and everyone else's lower-offs. As a belay karabiner the Bulletpoof is probably one of the best models out there, giving you everything you need in a more durable form while still retaining a reasonably light weight.
