4845 The hose test layout shall be straight without kinks or twists. Hose shall not be attached to any discharge at or adjacent to the pump operators position.
Before hose is pressurized all personnel participating in hose testing must be wearing a helmet and eye protection.
Nfpa hose testing requirements. This standard shall define the design and construction requirements for new fire hose the testing required to verify the design and construction and the inspection and testing required of all new fire hose. A11 All fire hose has an expected service life. Table 6112 Summary of Standpipe and Hose Systems Inspection Testing and Maintenance Item Frequency Reference Inspection Cabinet Annually 6218 Control valves Chapter 13 Gauges Weeklyquarterly Chapter 13 Hose Annually NFPA 1962625 Hose connection Annually 6213 Hose nozzle Annually and after each use NFPA 1962626.
This standard provides requirements for fire hose couplings nozzles and appliances in order to ensure a reasonable level of reliability when they are used at an incident. This Standard is no longer accepting Public Input due to the Emergency Response and Responder Safety Document Consolidation Plan consolidation plan as approved by the NFPA Standards Council. This guideline will be followed and accepted by all employees of Safety 1 st Fire Hose Testing.
- Section One -. The length of any hose to be tested shall not exceed 300 feet. Hose shall be laid out in as straight of a line as possible.
All fire service hose shall be tested. The stabilization period shall be not less than 1 minute per 100 feet 30 m of the hose in the test layout. After the stabilization period the hose layout shall hold the service test pressure for 3 minutes without further pressure boosts.
While the hose test layout is at the service test pressure it shall be inspected for leaks. The second component is the pressure requirements for the proper operation of fire service hose lines. The current requirement of 100 psi minimum and a maximum of 175 psi can be found in NFPA 14 but is not addressed in NFPA 1710.

Empty and recharge all stored pressure loaded stream fire extinguishers. Sprinklers NFPA 25 Main Drain Antifreeze Solution Valves Valve Components Pressure Reducing ValvesRelief Valves part flow. Requirements for Testing Occupant-Use Hose.
In-service hose designed for occupant use only shall be removed and service-tested as specified in Chapter 5 at intervals not exceeding 5 years after installation and every 3 years thereafter. Standpipes and fire hoses must comply with an overwhelming number of regulations from installation and design NFPA 14 1961 to couplings and attachments NFPA 1963 to inspection care use and testing NFPA 25. We have summarized a few of the inspection and testing requirements below for your reference.
The service test for hose of less than five inches in diameter shall be conducted as follows. Connect the hose to a discharge. Hose shall not be attached to any discharge at or adjacent to the pump operators position.
The total length of any hose-line in the. Attack fire hose shall be service tested to a minimum of 300 psi. Supply fire hose shall be service tested to a minimum of 200 psi.
Testing can be done on a fire departments own fire apparatus. All non-threaded hose connections shall be provided with locks to ensure against unintentional disconnection. The standard also covers.
USING A HOSE TESTING MACHINE If necessary see NFPA 1962 2018 Edition for additional details. Page 1 of 2 All personnel review procedures before starting. Before hose is pressurized all personnel participating in hose testing must be wearing a helmet and eye protection.
Personnel must remain behind on the intake side the hose. This is straight from the NFPA. 7121 The service test pressure for hose manufactured in July 1987 and after to meet the requirements of the 1987 and subsequent editions of NFPA 1961 Standard on Fire Hose is stenciled on each length of hose and reads Service Test to ___ psi per NFPA1962 or Service Test to ___ bar per NFPA1962.
Hose testing shall be completed annually and in conjunction with the guidelines set forth in NFPA 1962 Standard for the Care Use and Service Testing of Fire Hose Including Couplings and Nozzles. DURING TESTING ALL PERSONNEL SHALL WEAR THE FOLLOWING SAFETY EQUIPMENT. Fire Helmet to provide head eye and face protection.
A certified person needs to at the very least be familiar with the requirements in NFPA 10. Frequency Fire extinguishers need to have an external maintenance examination conducted on a yearly basis at the time of hydrostatic test or when specifically indicated by an inspection discrepancy. Nfpa fire hose testing requirements.
FIRE HOSE TESTING Per NFPA 1962. NHTS has designed and built equipment to safely test fire hose and that meet the NFPA standards. NFPA 1962 currently requires LDH to be tested at a minimum of 200psi and the Attack hose to be tested at a minimum of 300 psi.
Alternate pressures are available at the customers request. Appliance in a protective devise or cover capable of holding the appliance and testing. Hydrostatically test to a minimum 300psi.
Relief valves blanked off or closed if present c. Bleed air from the system. Hydrostatically pressure by 50 psi increments held.

The total length of any hose line in the hose test layout to be service tested shall not exceed 300 ft 91 m. 4845 The hose test layout shall be straight without kinks or twists. 4846 All 3 12 in.
89 mm and larger diameter hose shall be service tested while lying on a horizontal surface. All new systems are required to be tested hydrostatically at a minimum pressure of either 200 psi 138 bar or 50 psi 34 bar above the maximum discharge pressure whichever is greater at the fire pump discharge flange. Typically the requirement has been to test systems at 200 psi or 50 psi above the maximum pressure for two hours.
For example if a system has a maximum pressure of 175 then the system would require a hydrostatic test at 225 psi. Hose connections are required to be inspected annually for missing or damaged components gaskets leaks obstructions and threads. There are differing requirements for testing depending on the type of standpipe and devices installed.
NFPA defines 5-year and annual testing requirements for all pressure-reducing and relief valves while repeating the requirements for testing these devices that are specifically located at hose connections Class I and Class III systems and hose rack assemblies present in all Class II systems and some Class III systems.
