This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by August 2007, and conflicting national standards shall be withdrawn at the latest by August 2007. EN 15182 consists of the following parts, under the general title Hand-held branchpipes for fire service use: Part 1: Common requirements; Part 2: Combination branchpipes PN 16; Part 3: Smooth bore jet and/or one fixed spray jet angle branchpipes PN 16; Part 4: High pressure branchpipes PN 40. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

It deals with: safety requirements; performance requirements; test methods; classification and designation; information for use; marking and maintenance. This part of this European Standard applies to branchpipes as defined in Annex A of EN 15182-1:2007. NOTE 1 These branchpipes offer no or inadequate protection for firefighters when the spray angle is less than 30 ° and therefore, should not be used in high risk fire fighting situations such as internal attack. NOTE 2 These branchpipes should not be used when fighting fires in or near electrical installations when the spray angle is less than 30 ° without written authorisation from the manufacturer in the manual. This authorisation from the manufacturer should include safety distances. 2 Normative references The following referenced documents are indispensable for the application of this document.

Table 2 Maximum torques Type of operating element Torque Nm Lever 15 Valve handle 15 Rotating operating elements 10 Rotating inlet elements for fixed couplings 5 4.2.2.2 For branchpipes 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, the “closed“ position shall be clearly identified. 4.2.3 Jet adjustment positions The jet positions, if applicable, shall be clearly marked. 4.3 Hydraulic characteristics 4.3.1 Pressures The following pressures shall be used for determining the hydraulic characteristics: reference pressure: pR = 6 bar; nominal pressure: pN = 16 bar; test pressure: pt = 25,5 bar; burst pressure : pB = 60 bar. 4.3.2 Flow rates All flow rates indicated on the branchpipe shall be measured at straight jet and/or at the spray jet. Table 3 shall apply to deviations in flow rates which can be set at the reference pressure pR.

Key X Flow rate Q in l/min Y Effective throw eff d in m Figure 1 Effective throw 4.3.4 Spray jet If the branchpipe has a spray jet, the spray jet shall have a minimum spray angle of 15 °. 4.4 Leak-tightness The closed branchpipe shall show no leakage during 1 min at the test pressure pt = 25,5 bar. NOTE No leakage means no visible weeping or drop formation. The opened branchpipe shall show no leakage during 1 min at the nominal pressure pN = 16 bar.

The measurement shall be carried out when the system is stabilised. The maximum throw shall be given in the instruction handbook.
