Zafety Lug Lock™ temperature and vibration testing Testing performed by Bodycote Testing Group Parameters: 1. Three Zafety Lug Lock™units tested 2. Temperature testing at 25⁰C (77⁰F) , 50⁰C (122⁰F) and - 40⁰C (-40⁰F) 3. Vibration test at 30 Hz and 3 g acceleration amplitude 4. Each segment of the test was two hours with a total duration of 6 hours
Zafety Lug Lock™ temperature and vibration testing TEST PROCEDURE: • 4 nuts tightened to spec (450-500 psi) • 2 nuts hand tightened • White line applied to nuts and bolts to identify positioning • Vibration at specific temperature for 2 hours • Visual inspection of Zafety Lug Lock™unitsand nuts for any changes
