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.

Negative with Comment Keeping, Larry While I am in favour of the overall concept, I believe the proposed text needs additional revision. First, should be deleted, because it conflicts with Second further consideration should be given to As currently written it would be acceptable to put PVC pipe (ie combustible) in an uncovered floor trench - the requirement that the trench be covered was deleted. Third, for an arched trench with 24 inches of clearance is in conflict with , which only calls for 12 inches clearance below a footing. Fourth, why should the trench have to be poured concrete before using NFPA 13 materials. The trench should equally be permitted to be block or brick or stone or of other non-combustible construction.

32 A A grate or steel plate are common methods of accessing the trench. A The intent of this requirement is to prevent the piping from being exposed to standing water. Draining can be accomplished by providing a floor drain, sloping of the trench, or other approved method. A It is the intent of this section to require a valve at each point where the pipe enters the trench when the trench traverses the entire building. Generally if the piping terminates at a point within the building, a valve is usually provided at a riser, allowing isolation of the pipe section in the trench.

50 46 of 60 11/29/2016 8:50 AM First Revision No. 20-NFPA [ Section No. A ] A A For example, consider a sprinkler system has for its water supply with a connection to a public water service main for its water supply. A 100 psi (6.9 bar) rated pump is installed in the connection. With a maximum normal public water supply of 70 psi (4.8 bar), at the low elevation point of the individual system or portion of the system being tested and a 120 psi (8.3 bar) pump (churn) pressure, the hydrostatic test pressure is 70 psi (4.8 bar) +, 120 psi (8.3 bar) +, 50 psi (3.5 bar), or 240 psi (16.5 bar). To reduce the possibility of serious water damage in case of a break, pressure can be maintained introduced by a small pump, the main controlling gate meanwhile being kept shut during the test. Polybutylene pipe will undergo expansion during initial pressurization. In this case, a reduction in gauge pressure might not necessarily indicate a leak. The pressure reduction should not exceed the manufacturer's specifications and listing criteria. When systems having rigid thermoplastic piping such as CPVC are pressure tested, the sprinkler system should be filled with water. The air should be bled from the highest and farthest sprinklers. Compressed air or compressed gas should never be used to test systems with rigid thermoplastic pipe. A recommended test procedure is as follows: The water pressure is to be increased in 50 psi (3.5 bar) increments until the test pressure described in is attained. After each increase in pressure, observations are to be made of the stability of the joints. These observations are to include such items as protrusion or extrusion of the gasket, leakage, or other factors likely to affect the continued use of a pipe in service. During the test, the pressure is not to be increased by the next increment until the joint has become stable. This applies particularly to movement of the gasket. After the pressure has been increased to the required maximum value and, it is held for 1 hour, the pressure is to be decreased to 0 psi 2 hours while observations are made for leakage. The pressure is again to be slowly increased to the value specified in and held for 1 more hour while observations and the pressure readings are made for leakage and the leakage measurement is made checked. Submitter Information Verification Submitter Full Name: David Hague Organization: [ Not Specified ] Street Address: City: State: Zip: Submittal Date: Mon Jul 11 15:26:02 EDT 2016 Committee Statement Committee Statement: The revisions to the first paragraph are just editorial, to provide better clarity that the matter is just an example of how to determine the test pressure. The revision to the second paragraph is necessary because after the test pressure is introduced into the system, the pump needs to be shut off, whereas the current text suggests that it can be used to maintain the pressure. The revisions to the last paragraph are to provide better coordination between the Annex text and the requirement of Section , which deals with a pressure variation of ±5 psi and not with leakage measurement. Also, it makes no sense to reduce the pressure after 1 hour to check for leakage. If the pressure is reduced the test would be skewed, because the leakage could be
