The door shall not be provided with a lock or similar device. 8.4 A means provided for use in opening the door of a cabinet shall be suff
27、iciently large to reduce the likelihood of entrapment or jamming of fingers. PERFORMANCE 9 Installation and Operation Test 9.1 In order to determine compliance with the requirements of 5.1 and 8.1, a sample of a cabinet is to be installed on a wooden test fixture, following the manufacturers install
28、ation instructions. The piping to the cabinet then is to be pressurized to maximurn rated pressure and the fire hose operated in accordance with the manufacturers operating instructions. There shall be no kinking or twisting of the hose, nor development of a condition during installation or operatio
29、n of the cabinet that may interfere with its intended use. 10 Nozzle Range Test 10.1 At pressures in the range of the rated minimum service pressure and 100 psig (689 kPa), the range of the hose stream shall be not less than 19 nor more than 31 feet (5.8 and 9.5 m). 10.2 The nozzle is to be held at
30、an elevation of 3 feet (0.9 m) above the floor in a horizontal position and adjusted to the straight stream position. The inlet pressure is to be varied from the rated minimum service pressure to 100 psig (689 kPa), in uniform increments providing at least ten test pressures, and the discharge range
31、 of the nozzle recorded. 11 Leakage Test 11.1 A valve, hose, hose nozzle, coupling, or other part subject to hydrostatic pressure in use shall withstand for 1 minute, without leakage, a pressure equal to twice the rated maximum working pressure. 11.2 Samples of the part are to be filled with water a
32、nd vented of air. The internal pressure than is to be increased to twice the rated maximum working pressure and maintained for 1 minute. 12 Hydrostatic Strength Test 12.1 A part subject to hydrostatic pressure in use shall withstand for 1 minute, without rupture, a pressure equal to four times the r
33、ated maximum working pressure. 12.2 Samples are to be filled with water and vented of all air. The test pressure then is to be gradually increased to four times the rated working maximum pressure and maintained for 1 minute. 13 Pull Strength Test 13.1 The mean value of the force required to separate
34、 a hose from its coupling, minus three standard deviations, shall be greater than or equal to 100 pounds-force (445 N). 13.2 A minimum of ten samples are to be tested. The samples are to consist of short lengths of hose with one male and one female coupling on each end. The samples are to be pulled
35、on a standard tensile testing machine at a speed of 0.20 inch per minute (0.085 mm/s) until the coupling separates from the hose, at which time the separation force is to be recorded. 13.3 The unbiased standard deviation is to be used to calculate the minimum pull strength. 14 Cold Resistance Test 1
36、4.1 A hose shall not crack or show other evidence of physical damage to the jacket or lining when subjected to the test described in 14.2. In addition, following the test described in 14.2, the hose shall not leak or show breakage of the thread in the jacket when the hose is allowed to thaw for 24 h
37、ours at room temperature and then subjected to the Hydrostatic Strength Test, Section 12. 14.2 A 3-foot (0.9-m) long sample of the hose, with test fittings, is to be immersed in a water bath at room temperature for 24 hours. The sample then is to be removed from the bath, exposed to room atmosphere
38、for 15 minutes, and placed in a cold box maintained at 32F (0C) for 24 hours. Immediately after removal from the box, the sample is to be twice bent double on itself (180 degrees); first in one direction, and then in the opposite direction. 15 Accelerated Aging Test 15.1 After-being conditioned as d
39、escribed in 15.2, there shall be no cracking or other evidence of deterioration of the hose or other nonmetallic components of a cabinet, and the cabinet shall operate as intended, without leakage, when subjected to the Installation and Operation Test, Section 9. 15.2 Each of the four samples of the
40、 complete cabinet, less fire extinguisher, are to be installed in an air oven and conditioned for 30, 60, 90, and 180 days, respectively, at 65C (150F). 16 Water Immersion Test 16.1 A hose shall comply with the requirements of the Hydrostatic Strength Test, Section 12, after being submersed to a dep
41、th of 18 inches (460 mm) in tap water at room temperature for 72 hours. 17 Adhesion Tests 17.1 General 17.1.1 The rate of separation of a l-ll2-inch (38-mm) strip of the hose lining from the jacket shall be not greater than 1 inch (25.4 mm) per minute when tested with a weight of 12 pounds (5.4 kg)
42、in accordance with 17.3.1 - 17.4.1. 17.1.2 If a rubber backing is used between the lining and the jacket, the rate of separation of a l-1/2-inch (38-mm) strip of lining from the backing and the rate of separation of a 1 -l/2-inch strip of backing from the jacket shall be not greater than 1 inch (25.
43、4 mm) per minute when tested with a weight of 12 pounds (5.4 kg). See 17.4.2. 17.1.3 The requirements of 17.1.1 and 17.1.2 are not intended to exclude a construction that provides no adhesion between the jacket and lining along the fold, provided that the surface over which there is no adhesion does
44、 not involve more than 35 percent of the total surface. 17.2 Cover 17.2.1 The rate of separation of a l-l/2-inch (38-mm) strip of the cover from woven jacket shall be not greater than 1 inch (25.4 mm) per minute when tested with a weight of 10 pounds (4.5 kg) in accordance with 17.3.1 - 17.4.1.

L191 WI 9275745 OAr12520 105 MARCH 24,1999 SUBJECT 1630 17.3 Specimens 17.3.1 Specimens for the adhesion test are to be cut transversely. 17.3.2 Each specimen is to be 2 inches (51 mm) wide and is to be cut through so as to provide a rectangular sample 2 inches wide and as lo
46、ng as the full circumference of the hose. A strip of lining or cover 1-1/2 inches (38 mm) wide is to be accurately cut from the sample strip, and the cut is to extend through the lining or cover but not entirely through the jacket. This strip is to be separated from the jacket at one end to a distan
47、ce of approximately 1-1/2 inches, and a reference mark is to be placed on the jacket at the juncture of the jacket and the lining. 17.4 Test Procedure 17.4.1 With the separated jacket gripped in a stationary clamp, the separated lining or cover is to be gripped in a freely suspended clamp hanging ve
48、rtically, to which the specified weight is to be attached, with provision for supporting and releasing the weight slowly and without jerking. The distance through which separation takes place is to be noted for 10 minutes, or until complete separation occurs. The rate of separation is to be the tota
49、l distance separated in inches (mm), measured to the nearest 0.1 inch (2.5 mm), divided by the elapsed time in minutes. 17.4.2 If a rubber backing is used between the lining and the jacket, the rate of separation of the lining from the backing and the rate of separation of the backing from the jacket are to be determined, using the methods described in 17.3.1 - 17.4.1. If either the rate of separation of the lining from the backing or the rate of separation of the backing from the jacket cannot be determined because the backing has a tendency to tear during the test, the rate of sepa
