BS/EN 15182-3-2019 pdf download.Portable equipment for projecting extinguishing agents supplied by firefighting pumps — Handheld branchpipes for fire service use Part 3: Smooth bore jet and/or one fixed spray jet angle branchpipes PN 16.
In addition to the requirements given in EN 15182-1:2019, this document applies to hand-held branchpipes with smooth bore jet and/or one fixed spray jet angle branchpipes with a nominal pressure of 16 bar (1,6 MPa) PN 16, with a maximum flow rate up to 1 000 I/mAn at a reference pressure of 6 bar (0,6 MPa). It deals with:
— safety requirements;
— performance requirements;
— test methods.
This document applies to branchpipes as defined in Annex A of EN 15182-1:2019.
WARNING 1 These branchpipes offer no or inadequate protection for firefighters when the spray angle is less than 30 ° therefore, are not be used in high risk firefighting situations such as internal attack.
WARNING 2 These branchpipcs should not be used when fighting fires in or near electrical installations when the spray angle is less than 30° wIthout written authorization from the manufacturer In the manual. This authorization from the manufacturer includes safety distances.

3.1
smooth bore bra nchpipe
branchplpe providing a solid water stream
The torques shall be measured in accordance with Table 2 . This test shall be conducted with water only. The forces needed to move the rotating elements which have detents shall be between 15 N and 75 N. Verification
— Measure the force of rotating elements which have detents En dry conditions without flowing.
— Make the rotating element turn 300 cycles without flowing water.
NOTE A rotation means rotating the element fully in one direction and back to the starting point.
— Measure the force without flowing water at the end of the previous test which shall remain in the range oflSNto 75N.
For hranchpipes that are opened and closed with a valve handle, the closed position shall be located In the direction of the flow. If a different operating element Is used, with the exception of a trigger, the VClosed position shall be clearly Identified.
Verification
Visual inspection.

4.2.3 Jet spray angle
The jet positions, if applicable, shall be clearly marked. Verification
Visual inspection.
lithe branchpipe has a spray let. It shall have a minimum angle of 15°.
Verification
The spray angle shall be measured using an angle measuring device.
4.3 Hydraulic characteristics
4.3.1 General
Unless otherwise specified, tests shall be carried out at the reference pressure PR. after the tests specified in EN 15182-1:2019, in the following order:
— 42.3 jet spray angle.
— 432 flow rates.
— 4.3.3 throw.
— 4.4 leak-tightness.
— 4 hydrostatic behaviour.
The following pressures shall be used for determining the hydraulic characteristics:
— reference pressure: PR = 6 bar ± 0,1 bar’,
— nominal pressure: PN = 16 bar;
— test pressure: Pt = 25.5 bar;
— burst pressure: PB = 60 bar.
NOTE No requirements are given concerning water distribution as it was not possible to obtain interpretable and conclusive data with the test equipment available at the time this document was written.
4.3.2 Flow rates
All flow rates indicated on the branchpipe shall be measured at straight jet and/or at the spray jet. Tabli3 shall apply to deviations In flow rates which can be set at the reference pressure PR.BS/EN 15182-3-2019 pdf download.
