Seismic Qualification Option for Ground and Roof Level Applications
• Meets 2003 IBC and ASCE 7 standards for seismic qualification in accordance with ICC ES AC156 testing protocol with an Importance Factor of 1.5 for 42 states.
• Some exceptions include California, Alaska, Hawaii, Kentucky, Tennesse, and Arkansas which are site specific.
• When mounted in accordance with published guidelines, the E-FlexTM enclosure is designed and constructed to withstand violent vibration loads.
• E-FlexTM Drives have been subjected to actual shaker table tests and not just theoretical anchorage and bolt-hole calculations for seismic ratings.
