AC 156 Seismic Testing: Acceptance Criteria for Seismic Certification by Shake Table Testing of Nonstructural Components.

Clark Testing offers full seismic testing, certification, and report submittal for testing to AC-156. The AC-156 seismic test specification defines the testing and requirements for equipment installed into newly constructed or renovation projects in the residential and commercial industries. This standard is the most common testing procedure for hospitals & healthcare facilities as determined by the State of California’s Office of Statewide Health and Planning Division (OSHPD) as well as the IBC (International Building Code).

Equipment installed in health care facilities in the state of California are required to be designed in order to withstand the effects from seismic activity. The OSHPD and AC-156 standards require structures and equipment to maintain their structural and functional integrity after an earthquake, making seismic testing a vital part of product validation.

Clark offers full OSHPD and IBC Certification services utilizing our tri-axial seismic shake table along with our partner network of structural Professional Engineers (PE) that are certified for OSHPD compliance.

The Seismic table at Clark Testing is capable of performing seismic testing on large packages up to 20,000 lbs. at 1g ZPA. The table can achieve 3g’s ZPA up to 10,000 lbs. & 5g’s for lower weight. The table has three (3) independent servo hydraulic actuators with 38,000 lbs. force +/- 5” stroke with peak acceleration of 15g – 18g.

In addition to AC-156 & OSHPD Seismic Certification, Clark’s laboratory also offers a full array of product validation and compliance testing including thermal aging and EMC/EMI testing.
