HVAC Seismic Design per IBC 1621.3 - where is 1621.3 ?

[SAK123]

I am in the process of checking a HVAC system for seismic requirements per IBC 1621.3 - a customer requirement.

However, in looking at the IBC 2006 document, I do not se 1621.3 anywhere.

Does anyone know what was the last year section 1621.3 was included in the IBC for seismic loading ?

It shows up in the 2000 IBC but not in the 2003 IBC.

Could be that for the 03 and 06 IBC's it is now in ASCE 7.
