EN 837-1, Pressure gauges — Part 1: Bourdon tube pressure gauges — Dimensions, metrology, requirements and testing EN 837-3, Pressure gauges — Part 3: Diaphragm and capsule pressure gauges — Dimensions, metrology, requirements and testing EN 16712-2, Portable equipment for projecting extinguishing agents supplied by fire fighting pumps — Portable foam equipment — Part 2: Pick-up tubes 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 inductor equipment which, using the Venturi principle, induces foam concentrates or other additives into a water flow to produce a solution at a predetermined ratio Note 1 to entry: Venturi principle: a negative pressure is created in a suction chamber by means of the injector effect. 3.2 regulating device p2 3.3 setting device device to select the proportion ratio SIST EN 16712-1:2015

EN 16712-1:2015 (E) 6 3.4 proportion ratio percentage of foam concentrates or additives in the foam water solution EXAMPLE If a hand-held foam branchpipe is used to flow 400 l/min of foam water solution at a proportion ratio of 3 %, the foam concentrate flow will be 12 l/min. 3.5 foam water solution homogeneous mixture of water and foam concentrate Note 1 to entry: Foam concentrates are defined in EN 1568 series. 3.6 pressures Note 1 to entry: Pressures are expressed in bar, measured with respect to atmospheric pressure. Note 2 to entry: 1 bar = 0,1 MPa (105 Pa). 3.6.1 foam branchpipe working pressure p1 pressure measured at the inlet of the foam branchpipe 3.6.2 outlet working pressure p2 pressure measured at the outlet of the inductor 3.6.3 inlet working pressure p3 pressure measured at the inlet of the inductor 3.6.4 nominal pressure pN maximum working pressure measured at the inlet of the inductor 3.6.5 test pressure pt static pressure used for leakage tests 3.6.6 burst pressure pB static pressure used for burst test SIST EN 16712-1:2015
