Table 8.6.1
Revised for consistency with NFPA 20 requirements.
FR 94
Table 9.1.1.2
Revised to indicate that it is only steel tanks without corrosion protection that need to be
inspected every 3 years and that it is all other tanks that have a 5 year frequency. This is
consistent with the text of Chapter 9.
FR 31, SR 22,
SR 64
9.1.2
Revised to use the term common components. Each of the specific system chapters has been
reformatted to use this term to provide consistent terminology when referring the user to
Chapter 13 for ITM activities for this equipment.
FR 60
9.2.1
9.2.2.1
Revised all tank inspection frequencies to quarterly where the components are supervised in
accordance with NFPA 72. All frequencies for components not supervised in accordance with
NFPA 72 have remained unchanged.
FR 32, SR 65
Revised 9.2.2.1 to indicate that the inspections are only required during heating season,
similar to what 9.2.2.2 said in previous editions.

Table 10.1.1.2
Revised to align inspection frequencies of fittings with that for the associated pipe and to
align the inspection of pipe supports with that for the associated hangers.
Revised frequencies for inspecting rubber gasket fittings to annually.
Removed flushing from the table because it is generally not part of the operational test of
water spray fixed systems and the code reference was unclear.
FR 21, SR 23
10.1.5
Revised to use the term common components. Each of the specific system chapters has been
reformatted to use this term to provide consistent terminology when referring the user to
Chapter 13 for ITM activities for this equipment.
FR 22
10.2.3.1
Revised to clarify that the intent of section item (4) is to inspect the condition of any installed
low-point drains. As previously written this was not clear.
Additionally, the protection of gaskets has been clarified and the intent would be consistent
with the requirements of NFPA 15.
FR 23
10.2.3.2
Revised to add braces to this section. The inspection of seismic braces is required for sprinkler
systems in Chapter 5 and should also be required for water spray systems.
FR 24
Table 11.1.1.2
Revised references in the table to shift the ITM requirements for waterflow devices to Chapter 13.
Added new row for Gauges because, as with all water-based systems, gauges should be
inspected regularly, but were previously omitted from this table.
FR 13, SR 24
11.1.2
Revised to use the term common components. Each of the specific system chapters has been
reformatted to use this term to provide consistent terminology when referring the user to
Chapter 13 for ITM activities for this equipment.
