Seismic Testing
Posted by Anthony from St. Louis, MO, US on September 20, 2010
Can you do the seismic testing yourself and report the results?
All tests must be performed by an independent laboratory with ISO (International Standards Organization) accreditation, or conducted under the supervision of a California licensed structural engineer. Alternatively, a California licensed civil engineer or mechanical engineer can conduct the testing, as long as the results are evaluated and signed off by a licensed structural engineer. OSHPD strongly recommends that a test plan be submitted, reviewed and approved prior to testing, to avoid problems.
OSHPD Certification
Posted by James from Nashville, TN, US on September 20, 2010
What’s the difference between OSHPD certification and preapproval?
Originally, OSHPD required that all critical equipment be tested and certified before it could be installed in a hospital. That requirement led to a significant backlog, so in 2009, OSHPD set up OSP, or OSHPD Special Seismic Certification Preapproval. With OSP, product lines could be evaluated using a combination of shake-table testing and structural analysis, done under certain specified conditions. Once preapproved, individual units can be installed without further testing.
OSHPD seismic standards
Posted by Edward from Los Angeles, CA, US on September 20, 2010
How do the OSHPD seismic standards relate to the IBC and CBC?
The current OSHPD seismic standards, detailed in OSHPD’s Code Application Notice CAN 201708A.5. (October 31, 2008), build on those previously established by the IBC (International Building Code, 2006 edition) and the CBC (California Building Code, 2007 edition). The CBC Chapter 1613A, on “Earthquake Loads,” also specifies ASCE/SEI 7-05 Minimum Design Loads for Buildings and Other Structures as the basis for design.
Are Mobile Gensets Covered?
Posted by Mike from Mandeville, LA, US on July 22, 2010
Are truck mounted mobile gensets covered under the new emission regulations? These specific gensets are used to supply the AC power needs of mobil test equipment.
Mobile gensets continue to follow the emission regulations for non emergency applications. So, in instances where emission regulations change from current tier level to T4i or T4 final, these would apply to mobile units as well. The exception to stay at current tier levels is for stationary emergency applications only.
How do the T4 regulations affect co-gen and peak-shaving applications?
Posted by Victor from Lisle, IL, US on June 21, 2010
I have a client that was considering using their standby generators for peak-shaving in exchange for better rates from their utility. Will the new T4 regulations allow this? What penalties are involved if they do it?
Victor,
thanks for the note. Sorry couldn't respond sooner.
To get back to your question, I assume we are talking about engines over 174 HP and their applications as the regulations shift to T4i starting 2011.
Only engines operating as emergency engines are allowed to stay at the existing tier levels. Peak Shaving would not be considered as an emergency application and thus a generator in this power bracket set used for peak shaving would have to meet T4i emission regulations.
I would trust the EPA for being a better source to comment on any penalties associated with such an incidence.
