Seismic Testing
Test Locations
For geographical locations susceptible to earthquakes,
it is critical to have equipment that is capable of
operating after a seismic event. The California
Office of Statewide Health Planning & Development
(OSHPD) has established a program that requires
all equipment used in any health care facility to be
pre-approved prior to installation within the state of
California. The International Building Code (IBC)
has also developed stringent building codes for
machinery that will be used in seismically active
areas. As a result, TCF has invested in a shake table
to simulate earthquakes that meet both IBC and
OSHPD requirements. The table is 10' x 10' and is
able to shake both floor mounted and ceiling hung
units. The maximum payload weight is 10,000 lbs.
Test Lab
Bump Testing
If it is required to determine the natural frequencies
of a fan rotor assembly and/or fan structure, TCF
offers bump testing to identify these frequencies.
Bump testing can be performed on a rotor assembly
suspended in air or on a structure mounted to the
floor and involves placing accelerometers in strategic
locations on the rotor assembly and/or fan structure.
Once the accelerometers are affixed to the unit, it is
impacted with a mallet and the response is measured
using diagnostic equipment to determine the natural
frequencies present in the unit.

Note: All custom Clarage impellers are bump tested.
