Officials earthquake-prone areas have new testing methods for equipment.
Officials in California and
other earthquake-prone areas have new testing methods for vibration
isolators and HVAC equipment,
under a new ASHRAE standard.
The American Society
of Heating, Refrigerating and Air-Conditioning Engineers has released Standard
171, “Method of Testing Seismic Restraint Devices for HVAC and R Equipment.” It
provides manufacturers a way to get their products pre-qualified for areas
where earthquakes are common.
ASHRAE officials said it is the first such standard for
seismic-restraint testing of non-structural components that does not require
shaker-table testing, which is often used in California. These tests determine
the maximum force restraints can stand.
Consulting engineers can use the standard as a reference in
specifications, officials added.
“This standard is a breakthrough for ASHRAE,”
said James Tauby, chairman of the committee that wrote the standard. “This new
national standard moves testing from the West Coast to the entire United
ASHRAE has new seismic testing standard
