21、 Division1, Hazardous (Classified) Locations, UL 913.4.5 Automatic hose nozzle valves are required to separate or break so that the valve body and the spoutseparate. Some hose nozzle valves are provided with a shear groove that aides this break. Theinstallation of a reader may interfere with the sep
22、aration or breakage such that the valve body an the spoutdo not separate. In order to verify that this does not occur, hose nozzle valves intended to be used withthis reader shall be subjected to the Pull Test, Section 6, under all of the following conditions:a) When installed as intended, the reade
23、r covers the shear groove on the spout orb) When installed as intended, the reader covers any part of the spout for hose nozzle valvesnot provided with a shear groove.4.6 Fluid confining parts of the hose nozzle reader shall be metallic materials. These parts shall complywith the Deformation Test, E
24、xternal Leakage Test, and Hydrostatic Strength Test in the Standard for HoseNozzle Valves, UL 2586.5 Batteries5.1 Batteries provided in products covered by this outline shall comply with one of the followingstandards:a) Standard for Lithium Batteries, UL 1642 orb) Standard for Household and Commerci
25、al Batteries, UL 2054.PERFORMANCE6 Pull Test6.1 An automatic hose nozzle valve shall shear or break off so as to separate the valve body from thespout when subjected to a right angle pull force of:a) Not more than 150 pounds (668 N) for a hose nozzle valve with a spout diameter less than1 inch (25.4
26、 mm) orb) Not more than 180 pounds (801 N) for a hose nozzle valve with a spout diameter of 1 inch(25.4 mm) or greater.6.2 Compliance with 6.1 is capable of being obtained by a weak section groove in the spout located notmore than 1 inch (25.4 mm) from the end of the valve body or body adapter and d
27、esigned to fracture uponapplication of the specified right angle pull force or less. To determine conformance with this requirement,the reader shall be installed as intended on the hose nozzle valve during this test. The spout portion ofthe hose nozzle valve shall be fixed at the point closest to th
28、e reader, and the specified right angle pullforce applied using a length of gasoline hose of the same size as the inlet of the hose nozzle valveattached to the test sample at the inlet end of the valve body.SEPTEMBER 28, 2012UL 1238A6UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR
29、DISTRIBUTION WITHOUT PERMISSION FROM UL6.3 Following this test, the spout shall be replaced and the valve shall be subjected to the Seat LeakageTest and External Leakage Test in accordance with the Standard for Hose Nozzle Valves, UL 2586.7 Drop Test7.1 After this test, any cracks or openings that d
30、evelop must be such that the internal circuits are notaccessible with the finger probe shown in Figure 7.1.7.2 A set of two samples of the reader are required for this test. The reader shall be installed on the hosenozzle valve it is intended for use with. The test shall be performed on one sample o
31、f the set at roomtemperature (nominal 25C or 77F) and on the second sample of the set, conditioned in a cold chamberequal to the manufacturers lower rated ambient temperature but not at a temperature higher than minus30 2C (minus 22 4F) for 24 hours. For the conditioned sample, the sample shall be r
32、emoved from thechamber prior to being subjected to the drop test. Gloves shall be worn when handling the conditionedsample to minimize heat transfer.7.3 With reference to 7.2, a different set of two samples of the reader is needed for each different hosenozzle valve to be included.7.4 The two sample
33、s are to be subjected to 4 impacts that result from being dropped onto a concretesurface in positions likely to produce the most adverse results. The height of the drop shall be 1.0 m (39.4inches). Each drop should impact a different location on the reader. If the spout breaks off during this test,t
34、hen it shall be replaced or secured to the hose nozzle valve so as not to reduce the weight of the hosenozzle valve during this test.This is generated text for figtxt.SEPTEMBER 28, 2012 UL 1238A 7UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION ORDISTRIBUTION WITHOUT PERMISSION FROM U
