UL 47:2017 pdf free download – STANDARD FOR SAFETY Semiautomatic Fire Hose Storage Devices.
13 Fire Hose
13.1 A fire hose intended for use with an SHSD shall comply with the requirements of the Standard for
Lined Fire Hose for Interior Standpipes, UL 219, or the Standard for Lined Fire Hose and Hose
Assemblies, UL 19.
PERFORMANCE
14 General
14.1 When an SHSD is tested in accordance with these requirements, no parts shall be thrown, and
resistance to damage of the fire hose or component parts of the SHSD by handling shall be demonstrated.
15 Installation Test
15.1 One operator shall be able to replace the specified length of fire hose onto an SHSD when the
SHSD is mounted or supported in its intended position.
16 Operational Tests
16.1 Samples
16.1.1 A total of six sample SHSD’s are to be tested as specified in 16.1.2 and 16.1.3.
16.1.2 The tests specified in 16.2.1 — 16.3.2 are to be conducted four times on two “as received” sample SHSD’s using the specified length of fire hose; using two sets of SHSD’s with new fire hose as received from the manufacturer, and repeated with the fire hose that was used to conduct the Water retention test and the Run-off and release test which has been drained and reinstalled into the SHSD in accordance with the instructions marked on the device.
16.1.3 The tests specified in 16.2.1 — 16.3.2 are to be conducted four times after each exposure time on two aged sample SHSD’s using the specified length of fire hose; using two sets of SHSD’s with fire hose aged as specified in the Accelerated Air-Oven Aging Test, Section 17, and repeated with the aged fire hose that was used to conduct the Water retention test and the Run-off and release test, which has been drained and reinstalled into the SHSD in accordance with the instructions marked on the device.
16.2 Water retention test
16.2.1 An SHSD shall prevent the stored fire hose from filling with water beyond the third loop from the standpipe end within 2 minutes after the hose valve is fully opened. Also, operation of the SHSD and removal of the fire hose through any point of an arc of 180 degrees (90 degrees when in a cabinet) shall not be impaired.
16.2.2 An SHSD with the fire hose in a stored position is to be attached to a water source capable of maintaining maximum service pressure. The hose valve controlling the SHSD is to be fully opened and the specified service pressure maintained for 2 minutes in order to verify compliance with the requirements in 16.2.1.
16.3 Run-off and release test
16.3.1 At the completion of the water retention test and with the maximum service pressure maintained, the fire hose is to be run off free of the SHSD by one operator to its full length in the direction considered most severe. The hose shall run off without kinking, binding, or tangling.
16.3.2 Next, with all of the fire hose except for the last fold run off the SHSD and with the maximum service pressure maintained, the force necessary to release the last fold is to be determined by attaching a spring scale to the end of the fire hose and applying a straight horizontal pull. The SHSD, fire hose, nozzle, and spring scale are to extend in the same direction. The water retaining device shall be released from the standpipe end of the hose with a force not exceeding 25 pounds (111.2 N), applied at the nozzle for not more than three pulls. The retaining device shall not show evidence of wear.
16.4 Secureness test
16.4.1 The means provided to secure the nozzle when the nozzle is not in use shall not allow the nozzle to fall free when the nozzle is subjected to a vertical static load equal to twice the weight of the nozzle.
