Seismic Requirements



Meeting Seismic Requirements with Carrier Chillers

Previously, manufacturers would provide calculations as proof that equipment would maintain operation after a seismic event. Now, equipment must be tested on a “shaker table” in a lab.

What Agency or Code Regulates This Testing?

ICC Evaluation Service, Inc., a non-profit organization has developed a test plan known as AC156 – Acceptance Criteria for Special Seismic Qualification by Shaker Table Testing of Nonstructural Components & System -- which is acceptable to IBC, UBC and other local building code governing agencies

Carrier’s water-cooled chillers (19XR(V), 23XRV, 30XW, 30HX and 30MP), air-cooled chillers (30XA, 30RB, 30RAP) and split-systems (38AP/09DP) are special seismic compliant.
