of 48 7/1/2016 1:49 PM Public Input No. 3-NFPA 24-2015 [ New Section after 1.4 ] A.1.4 It is the intent of the committee to recognize that future editions of this standard are a further refinement of this edition and earlier editions. The changes in future editions will reflect the continuing input of the fire protection community in its attempt to meet the purpose stated in this standard. Compliance with all requirements of a future edition could be considered as providing an equivalent level of system integrity and performance of the system. Statement of Problem and Substantiation for Public Input Many AHJ's will not recognize future editions. This annex note is intended to give guidance that use of an entire future edition of the standard could be considered an equivalency as allowed in 1.4. This language will be proposed to other sprinkler standards and has been accepted by NFPA 14 & NFPA 25.

of 48 7/1/2016 1:49 PM Public Input No. 11-NFPA 24-2016 [ New Section after 5.1.2 ] 5.1.2.1 Where a waterflow test was conducted, the volume and pressure available for use for a fire protection system shall be determined from either 5.1.2.1.1 or 5.1.2.1.2. 5.1.2.1.1* Knowledge of the water supply and engineering judgment taking into account reasonable daily and seasonal fluctuations not extreme conditions. 5.1.2.1.2* Use of the following formula: P = The pressure available from the water supply to use for a fire protection system that will be calculated for a given flow (Q) Q = The flow that will be used to calculate the available pressure from the water supply. P R = The residual pressure measured during the waterflow test while the flow Q R was discharging from the water supply. P S = The static pressure measured during the waterflow test. Q R = The flow discharging from the water supply when P R was measured. P L = The expected low static pressure at the location of the test results accounting for daily and seasonal fluctuations (not extreme conditions) obtained from the water utility. Where the water authority does not provide P L, see 24.2.2.2.1.3. 5.1.2.1.3 Where the water authority does not provide a value for P L, the value of P L shall be calculated from the following formula: P L = P S 10 psi Additional Proposed Changes File Name Description Approved Safety_Margin_Proposal- NFPA_24.docx Statement of Problem and Substantiation for Public Input This is how the three proposals on this subject will look when put together. Note that this also has the formula in it, which I cannot get into Terra View There needs to be a reasonable adjustment to water supply data in order to accommodate changes due to daily and seasonal fluctuations. The fact that this is currently not a requirement allows the design of fire protection systems that are known by the designer to have an ineffective water supply almost immediately after installation. This proposal takes care of the traditional arguments against a mandated safety margin by creating a standardized method of calculating that safety margin; however, this standardized method is only used if there is no information regarding the water utility. So, those situations where the fluctuations in the water delivery are known at a particular location, then these take priority. Spelling out the fact that NFPA 24 is not expecting unusual circumstances like water main breaks and 100 year droughts should help alleviate liability concerns on the part of the water utility, which should lead to a more open dialog between the fire protection professional and the water utility representative. The reality is that extreme conditions like 100 year droughts and water main breaks are better handled by the Impairment Procedures of NFPA 25. One of the concerns about this proposal last cycle was that there was no way to account for the situation where the water utility brings more pumps on line as the flow demand increases. These situations produce a water Page 16 of 80

Insert new sections as follows: Water Supply Adjustment Proposals Put Together 5.1.2.1 Where a waterflow test was conducted, the volume and pressure available for use for a fire protection system shall be determined from either 5.1.2.1.1 or 5.1.2.1.2. 5.1.2.1.1* Knowledge of the water supply and engineering judgment taking into account reasonable daily and seasonal fluctuations not extreme conditions. 5.1.2.1.2* Use of the following formula: P Q Q R 1.85 PR PS PL P = The pressure available from the water supply to use for a fire protection system that will be calculated for a given flow (Q) Q = The flow that will be used to calculate the available pressure from the water supply. PR = The residual pressure measured during the waterflow test while the flow QR was discharging from the water supply. PS = The static pressure measured during the waterflow test. QR = The flow discharging from the water supply when PR was measured. PL = The expected low static pressure at the location of the test results accounting for daily and seasonal fluctuations (not extreme conditions) obtained from the water utility. Where the water authority does not provide PL, see 24.2.2.2.1.3. 5.1.2.1.3 Where the water authority does not provide a value for PL, the value of PL shall be calculated from the following formula: PL = PS 10 psi A.5.1.2 An adjustment to the waterflow test data to account for the following should be made, as appropriate: (1) Daily and seasonal fluctuations (2) Possible interruption by flood or ice conditions (3) Large simultaneous industrial use (4) Future demand on the water supply system (5) Other conditions that could affect the water supply Page 17 of 80

A.5.1.2.1.1 The purpose of the adjustment is to take into account reasonable daily and seasonal variations in the water supply, which are easily predicted and tracked by a water utility. It is not the intent to use this section to account for unusual conditions such as 100 year droughts or water main breaks. These unusual conditions are handled through the Impairment Procedures of NFPA 25 and should not be considered when determining the ability of a water supply to meet the demand of a fire protection system under more normal circumstances. A.5.1.2.1.2 Consider the following example. A waterflow test is conducted at a location where a city water main is going to be tapped for a new sprinkler system. During the test, the static pressure is measured at 70 psi, the residual pressure is measured at 50 psi while 1300 gpm was discharging from a nearby hydrant. The water utility is contacted and they indicate that a reasonable low static pressure accounting for typical daily and seasonal fluctuations in this area is 55 psi. The equation that describes the water supply available for a fire sprinkler system would be: P Q 1300 1.85 50 70 55 There are two ways to use this formula. One would be to assume two different values for Q, calculate P and then draw a graph on log 1.85 paper. Any fire sprinkler system demand falling on or below the line on this graph would be acceptable in accordance with NFPA 13 to work with this water supply. In this case, the two easiest flows to pick for Q would be 0 and 1300 gpm. When Q = 0, P is simply 55 psi. When Q = 1300 gpm, P = 35 psi. These two points can be plotted on log 1.85 paper as shown in Figure A.5.1.2.1.2. The second way to use this formula would be to calculate the fire protection system and determine the flow necessary to make the system work. Plug this flow into the formula above and see what the available pressure from the water supply will be at that flow. For example, if a sprinkler system connected to this water supply had a demand of 580 gpm, the available pressure from the water supply would be: P 580 1300 1.85 50 70 55 P = (-20)(0.225) + 55 P = 50.5 psi So, as long as the sprinkler system has a pressure demand less than or equal to 50.5 psi, it will work with this water supply.

of 48 7/1/2016 1:49 PM supply curve that looks more like a saw-tooth configuration than a line. That concern has been handled with the proposed language in the new section 5.1.2.1.1. Another of the concerns last cycle about this proposal was the fact that the modified line was not parallel to the original test line, and might cross the test line at a high flow. This concern has been mitigated by making the line parallel to the test line, which is more representative of what will happen in the real world anyway.

5 of 48 7/1/2016 1:49 PM Public Input No. 10-NFPA 24-2016 [ Section No. 10.10.2.2.1 ] 10.10.2.2.1 * All piping and attached appurtenances subjected to system working pressure shall be hydrostatically tested at gauge pressure of 200 psi (13.8 bar) or 50 psi (3.4 bar) in excess of the system working pressure, whichever is greater, and shall maintain that pressure at gauge pressure of ±5 psi (0.34 bar) for 2 hours. Aternatively, pressure testing of Polyethylene piping may be conducted in accordance with the requirements and recommendations of ASTM F 2164(Field Leak Testing of Polyethylene Pressure Piping Systems Using Hydrostatic Pressure). Statement of Problem and Substantiation for Public Input due to the viscoelastic stress relieving nature of polyethylene pipe, the actual loss as shown by gauge pressure may fall below the allowable listed in 10.10.2.2.1 as currently written. The proposed addition of the ASTM standard would allow for a testing protocol that is commonly used with HDPE piping systems. This change may be better suited as a new subparagraph to section 10.10.2.3 instead of where I proposed placement.

8 of 48 7/1/2016 1:49 PM A.5.1.2 An adjustment to the waterflow test data to account for the following should be made, as appropriate: (1) Daily and seasonal fluctuations (2) Possible interruption by flood or ice conditions (3) Large simultaneous industrial use (4) Future demand on the water supply system (5) Other conditions that could affect the water supply.1.1 The purpose of the adjustment is to take into account reasonable daily and seasonal variations in the water supply, which are easily predicted and tracked by a water utility. It is not the intent to use this section to account for unusual conditions such as 100 year droughts or water main breaks. These unusual conditions are handled through the Impairment Procedures of NFPA 25 and should not be considered when determining the ability of a water supply to meet the demand of a fire protection system under more normal circumstances. A.5.1.2.1.2 Consider the following example. A waterflow test is conducted at a location where a city water main is going to be tapped for a new sprinkler system. During the test, the static pressure is measured at 70 psi, the residual pressure is measured at 50 psi while 1300 gpm was discharging from a nearby hydrant. The water utility is contacted and they indicate that a reasonable low static pressure accounting for typical daily and seasonal fluctuations in this area is 55 psi. The equation that describes the water supply available for a fire sprinkler system would be: There are two ways to use this formula. One would be to assume two different values for Q, calculate P and then draw a graph on log 1.85 paper. Any fire sprinkler system demand falling on or below the line on this graph would be acceptable in accordance with NFPA 13 to work with this water supply. In this case, the two easiest flows to pick for Q would be 0 and 1300 gpm. When Q = 0, P is simply 55 psi. When Q = 1300 gpm, P = 35 psi. These two points can be plotted on log 1.85 paper as shown in Figure A.5.1.2.1.2. The second way to use this formula would be to calculate the fire protection system and determine the flow necessary to make the system work. Plug this flow into the formula above and see what the available pressure from the water supply will be at that flow. For example, if a sprinkler system connected to this water supply had a demand of 580 gpm, the available pressure from the water supply would be: P = (-20)(0.225) 55 P = 50.5 psi So, as long as the sprinkler system has a pressure demand less than or equal to 50.5 psi, it will work with this water supply. Sprinkler system demand can be anywhere in shaded region A-24-2-2-2-1.tiff Figure A.5.1.2.1.2 Available Water Supply Curve for Example in Section A.5.1.2.1.2 Figure Page 51 of 80
