Caterpillar's diesel generator sets for the North American market have been certified to meet the seismic provisions of the International Building Code (IBC). Additionally, 19 of the company's diesel generator sets, ranging from 11-kW to 4-MW, received Special Seismic Certification Preapproval from the California Office of Statewide Health Planning and Development (OSHPD) .
To receive IBC certification and OSHPD preapproval, an independent shake table test was performed on the power generation equipment. Structural engineer contractors and Tobolski Watkins Engineering Inc. conducted the test at the U.S. Army Construction Engineering Research Laboratory (CERL) in Champaign, Illinois.
The International Code Council (ICC) publishes the IBC, which is obtained when an independent agency reviews and certifies the products, deeming them capable of withstanding a given seismic force or wind load. To receive Special Seismic Certification Preapproval, manufacturers of generator sets must show documentation proving that the equipment has passed a shake test in accordance with ICC-ES AC-156, meeting seismic requirements for an earthquake.
With the preapproval, power solutions and other critical equipment may be installed by critical care facilities in California without the need to perform state-mandated shake testing.
