5. The design of seismic restraints for sprinkler piping in compliance with NFPA 13 using a design acceleration of 0.15 is acceptable in lieu of compliance with these provisions. 6. Seismic restraints are not required for any of the following conditions for other piping systems of HVAC ducts: 1. Piping or ducts suspended by individual hangers 12 inches or less in length from the top of the pipe or duct to the supporting structure. 2. Piping in boiler and mechanical rooms which has less than 1-1/4 inches inside diameter. 3. Piping in other areas which has less than 2-1/2 inches inside diameter. 4. Ducts which have a cross-sectional area less than 6 square feet.

2. Where equipment is resiliently mounted on springs or other types of vibration isolation supports, such supports shall have limits and stops to resist seismic deflection and forces.
