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

my motivation
keeping people off the ground
aiding and abetting my puppeteers

the shape of the equipment space
• 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

standards talk/ACCT 2008 34
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
