climbing, teaching, research,

modeling, consumption

of German beer, napping through

UIAA meetings

I’m not a guide, so I can’t tell you how to climb.

• assumes use of dynamic rope• onus on user to inspect & reject• single pull test to failure, no fatigue test• no corrosion testing• test is done on unused equipment in controlled circumstance

• safety factors may be less than 1

whither?climbing popularity → increased standards activity

increased emphasis on use, ergonomics, and psychology

increased systems analysis

increased self certifiable criteria

US based, independent testing

new standards for new branches of climbing

increased education of user
