15. Background The International Code Council s International Building Code IBC is the primary code document for the design and installation of building systems This has brought about increased scrutiny of mechanical and electrical equipment that is used in the operation of facilities particularly those buildings designated as essential facilities Previously codes focused only on preventing equipment from breaking free from anchoring and becoming projectiles and did not consider its structural integrity These new codes depending on the Use Group and Importance Factor of the building may require equipment to function after a seismic event IBC 2009 and 2012 has made the manufacturer of mechanical and electrical equipment responsible for designing testing and certifying systems Emerson through a recognized approved agency has conducted analytical modeling and dynamic shake table testing of the Liebert DSE to provide an option for those systems requiring seismic certification of compliance The seismic shake table testing was conducted in accordance with ICC ES AC 156 This certification goes beyond the equipment s ability to withstand seismic forces The IBC system approach includes the equipment equipment anchoring and the connections to the equipment power water supply and return and ducting In essential applications the equipment must be capable of performing its primary function after a seismic event within the limit of certif
