NOTE: The intent of this specification is to
induced by earthquakes for mechanical equipment and
systems described herein. The design seismic
lateral forces are in addition to the "normal"
gravity forces (weight) acting on the components of
a system.
Equipment in the following seismic design categories
do not require protection from seismic events (refer
to Chapter 4 of TI 809-04 for definition of
categories A through F; note that Chapter 10 of TI
