Replace Section A.5.2.1.1.6 as follows:
A.5.2.1.1.6 Suspended ceilings are those ceilings utilizing ceiling tiles installed on a grid where the ceiling tiles can be removed. This includes ceiling tiles held in place with hold-down clips, as in fire-rated ceiling construction. This does not include a suspended gypsum wallboard ceiling unless such ceiling is provided with an access opening.
Certain concealed spaces are required by the California Building Code to be provided with access openings. Such concealed spaces include attics, mansard spaces, under-floor spaces, under stages, under platforms or decks, and similar accessible spaces. Accessible concealed spaces are provided with access openings for maintenance of mechanical and electrical services. Although the general public or building occupants do not normally access these spaces, maintenance personnel and contractors do access these spaces. While servicing mechanical or electrical equipment these people may damage or create an obstruction to sprinklers. In addition, during the normal life of a building, roof insulating materials may fall and cover a sprinkler, thereby obstructing the sprinkler in terms of insulating the thermal response element of the sprinkler and in terms of obstructing the spray pattern.
The intent of this section is to provide an inspection where access is provided for areas such as hard lid ceilings. Where no access is provided, it is not the intent of this section to require access to be added for the purpose of performing this inspection.
Add Section A.5.3.1.3 as follows:
A.5.3.1.3
Sprinkler Testing. Records should be maintained by the owner or designated representative as defined in Section 4.1.1, identifying the location, types, and number of sprinklers removed for testing. These records are especially important when testing dry sprinklers as the shorter testing interval requirements may result in confusion related to which sprinklers should be selected for future testing.
Replace Section A.5.3.4 as follows:
A.5.3.4 Many refractometers are calibrated for a single type of antifreeze solution and will not provide accurate readings for the other types of solutions. Sampling from the top and bottom of the system helps to determine if the solution has settled. Antifreeze solutions are heavier than water. If the antifreeze compound is separating from the water due to poor mixing, it will exhibit a higher concentration in the lower portion of the system than in the upper portion of the system. If the concentration is acceptable near the top, but too low near the water connection, it may mean that the system is becoming diluted near the water supply. If the concentration is either too high or too low in both the samples, it may mean that the wrong concentration was added to the system. Two or three times during the freezing season, test samples can be drawn from test valve B as shown in Figure 7.6.2.1(1) of NFPA 13, especially if the water portion of the system has been drained for maintenance or repairs. A small hydrometer can be used so that a small sample is sufficient. Where water appears at valve B, or where the sample indicates that the solution has become weakened, the entire system should be emptied and refilled with acceptable solution as previously described.
See Figure A.5.3.4.1 for expected minimum air temperatures in 48 of the United States and parts of Canada where the lowest one-day mean temperature can be used as one method of determining the minimum reasonable air temperature. In situations where the piping containing the antifreeze solution is protected in some way from exposure to the outside air, higher minimum temperatures can be anticipated.
Where systems are drained in order to be refilled, it is not typically necessary to drain drops. Most systems with drops have insufficient volume to cause a problem, even if slightly higher concentration solutions collect in the drops. For drops in excess of 36 inches, consideration should be given to draining drops if there is evidence that unacceptably high concentrations of antifreeze have collected in these long drops.
When emptying and refilling antifreeze solutions, every attempt should be made to recycle the old solution with the antifreeze manufacturer rather than discarding it.
Add Section A.5.3.4.2 as follows:
A.5.3.4.2 The use of factory premixed solutions is required because solutions that are not mixed properly have a possibility of separating from the water, allowing the pure concentrate (which is heavier than water) to drop out of solution and collect in drops or low points of the system. Such concentrations are combustible and could present problems during fires. The properties of glycerin are shown in Table A.5.3.4.2.

Add Section A.7.3.1.1 as follows:
A.7.3.1.1
-- Underground Exposed Piping Investigation. Friction loss values for hydraulic calculations are always based on the specific Hazen Williams C factor/value assigned to the type of piping being utilized per NFPA 13. Over the life of an automatic sprinkler system, the interior surface of underground piping could deteriorate to a condition that the C factor is reduced to a lower value causing greater friction loss. However, it should be noted that the majority of piping installed since the early 1950s has been cement-lined cast iron, ductile iron, asbestos-cement, plastic, or fiberglass, which are not as susceptible to corrosion or internal deterioration. Where unlined piping is suspected, investigation of the condition of the inside surface is warranted. A flow test could be one form of Hazen Williams C factor/value discovery. Another method could be the use of a camera for the internal inspection of the pipe, or additional methods as approved by the AHJ may be acceptable.
Add Section A.7.3.1.1.1 as follows:
A.7.3.1.1.1 Water supply tests should be conducted in accordance with NFPA 291.
Add Section A.7.3.1.2 as follows:
A.7.3.1.2
-- Water Supply Evaluation. Because all hydraulic designed sprinkler systems are based on the available water supply at the time of installation, a reduction in the water supply yield could negatively affect the ability of the system to control a fire.

Add Section A.14.3.2.3 as follows:
A.14.3.2.3 The fire department connection shall be tested by back flushing through the inlets. The fire department connection check valve shall either (1) be removed and replaced with a spool piece, or (2) be replaced in the reversed position, or (3) the clapper shall be removed. The check valve clapper shall be inspected for proper operation. If the clapper does not move freely, it shall be repaired or replaced.
The fire department connection shall be back flushed at full flow. Where there is potential for damage to the building and grounds, hoses may be used to divert the water flow.
A hose having the same diameter as the fire department inlet shall be attached to each inlet. The maximum length of the hose shall be 50 feet. Where a greater length is needed, the diameter of the hose shall be increased one nominal diameter unless it can be determined that the flow rate is at least equal to the system demand.
At the completion of the back flush test, the check valve or clapper shall be reinstalled in the proper orientation. All control valves shall be returned to their normal position. The fire department connection shall be inspected to ensure the check valve is liquid tight.
Replace Annex B as follows:
Annex B
This annex is a part of the requirements of this NFPA 25 Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems 2013 California edition (based on NFPA 25, 2011 edition).
B.1. The forms listed in this Annex must be used with respect to the requirements of this standard (and Title 19, CCR) for the system being inspected, tested, or maintained, or any combination thereof. Because water-based fire protection systems are comprised of many components, it could be necessary to complete more than one form for each system.
The Office of the State Fire Marshal (OSFM), in conjunction with the OSFM Automatic Extinguishing Systems Advisory Committee (AES Advisory Committee) has developed the forms which shall be used to record the results of all inspections, testing, and maintenance of water-based fire protection systems. (Title 19, CCR, Section 906.4(a).)
B.2 Additional forms will be added as needed.
