5 5 of 13 1/13/ :40 AM Submittal Date: Tue Oct 13 14:25:26 EDT 2015 Committee Statement: Response Message: Added the friction loss test from ANSI/UL 19 to the hose characteristic requirements for attack hose. This provides manufacturers with a standard test method for conducting friction loss tests and purchases the ability to request the test results in accordance with Chapter 7. Specified the abrasion test for attack hose shall meet the requirements of multi-jacketed hose in ANSI/UL 19. This requirement specifies the most severe case of the abrasion test.

6 6 of 13 1/13/ :40 AM First Revision No. 12-NFPA [ New Section after ] Single jacket hose with a service test pressure of 300 psi (20.7 bar) and above shall be marked with the words "Single Jacket." Submittal Date: Wed Oct 14 09:04:08 EDT 2015 Committee Statement: Response Message: Added requirement that single jacketed hose capable of qualifying as attack hose (service test pressure at least 300 psi) be marked as such.

7 7 of 13 1/13/ :40 AM First Revision No. 10-NFPA [ Section No ] These markings shall be in a minimum of two places on each length of hose greater than 25 ft (7.6 m) in length, beginning 5 ft ± 6 in. (1.5 m ± 152 mm) from the ends of the hose unless the hose is marked at continuous intervals not exceeding 12 ft (3.7 m) Hose 25 ft (7.6 m) or less shall be marked in one place centered on the hose. Submittal Date: Tue Oct 13 17:18:16 EDT 2015 Committee Statement: Revised text to clarify for hose lengths 25 feet and less. Specified hose lengths 25 feet or less need to be marked in one place on the center of the hose. For hose lengths this short there is inadequate space to place markings at each and, while also being 5 feet from couplings.

8 8 of 13 1/13/ :40 AM First Revision No. 7-NFPA [ New Section after ] Friction Loss. The friction loss of attack hose diameters in. to in. (38 mm to 90 mm) shall be verified using the test procedures defined in ANSI/UL 19, Lined Fire Hose and Hose Assemblies, Friction Loss Test, or equivalent. Submittal Date: Tue Oct 13 14:59:17 EDT 2015 Committee Statement: Response Message: Added language to require design verification for friction loss test to generate the data that may be requested by consumers.

9 9 of 13 1/13/ :40 AM First Revision No. 8-NFPA [ Section No. A.1.2 ] A.1.2 This standard is not a detailed manufacturing or purchasing specification but can be referenced in purchase specifications as minimum requirements. Refer to Annex B in NFPA Submittal Date: Tue Oct 13 16:38:25 EDT 2015 Committee Statement: Response Message: Added language to clarify that purchasers should reference Specifying and Procuring Fire Hose, Annex B in the 2013 edition of NFPA 1962.

10 10 of 13 1/13/ :40 AM First Revision No. 6-NFPA [ Section No. A.5.1 ] A.5.1 The friction loss characteristics of fire hoses are an important consideration in the selection of hose. Friction loss varies considerably depending on the construction and design of the hose, the roughness of the lining, and its internal diameter, which may be different for different grades of hose. The type of couplings can also affect the friction loss. Where friction loss is important, side-by-side comparisons are recommended. The following test is recommended. All comparative tests should use 300 ft (90 m) of each type of hose to be tested laid side-by-side on a level surface. Commercially available line pressure gauges should be installed at the inlet and the outlet of the first 300 ft (90 m) of hose to be tested. A smooth bore nozzle of the size shown in Table A.5.1 should be used for the tests. Pressurize the test hose while the nozzle is fully open until a pitot gauge reading of the discharge reads 50 psi (3.5 bar). Read the pressure shown on the inlet and outlet line gauges. Subtract the outlet pressure from the inlet pressure and divide by 3 to determine the friction loss per 100 ft (30 m) of hose. Repeat the test for the next type hose to be tested. The hose with the lowest friction loss will flow the most amount of water for a given inlet pressure. Table A.5.1 Recommended Smooth Bore Nozzle Size for Testing Friction Loss in Fire Hose Hose Size Recommended Smooth Bore Nozzle Size in. mm in. mm Submittal Date: Tue Oct 13 14:56:54 EDT 2015 Committee Revised text to remove friction loss test method; the friction loss test from ANSI/UL 19 has
