Yes, note the exception applies in fully sprinklered buildings. 2009 IBC/IFC [F] 905.6 Location of Class III standpipe hose connections. "Class III standpipe systems shall have hose connections located as required for Class I standpipes in Section 905.4 and shall have Class II hose connections as required in Section 905.5." [F] 905.6.1 Protection. "Risers and laterals of Class III standpipe systems shall be protected as required for Class I systems in accordance with Section 905.4.1." [F] 905.4.1 Protection. "Risers and laterals of Class I standpipe systems not located within an enclosed stairway or pressurized enclosure shall be protected by a degree of fire resistance equal to that required for vertical enclosures in the building in which they are located." Exception: "In buildings equipped throughout with an approved automatic sprinkler system, laterals that are not located within an enclosed stairway or pressurized enclosure are not required to be enclosed within fire-resistance-rated construction." 2009 IBC/IFC IBC 102.4 Referenced codes and standards. "The codes and standards referenced in this code shall be considered part of the requirements of this code to the prescribed extent of each such reference. Where differences occur between provisions of this code and referenced codes and standards, the provisions of this code shall apply." IFC 102.7 Referenced codes and standards. "The codes and standards referenced in this code shall be those that are listed in Chapter 45 and such codes and standards shall be considered part of the requirements of this code to the prescribed extent of each such reference. Where differences occur between the provisions of this code and the referenced standards, the provisions of this code shall apply." Please note that I'm citing the Model Code (IBC/IFC) some jurisdictions, such as New Jersey amend the model codes.
