Overview

EN 16712-1:2015 is a CEN European Standard that specifies requirements and type tests for portable inductors PN 16 used to proportion foam concentrate or other additives into a water stream by the Venturi principle. It applies to standalone inductors supplied by fire‑fighting pumps and excludes inductors integrated into self‑inducting foam branchpipes or units manufactured before publication.

Key topics and technical requirements

• Scope and principle
  • Applies to Venturi‑type inductors designed to inject foam concentrate/additives into water at predetermined proportions.
  • Not applicable to integrated self‑inducting branchpipes or pre‑existing units.
• Types and nominal flows
  • Inductors are categorized (Z0.5, Z1, Z2, Z4, Z8 and R variants) by nominal foam‑water solution flow rates (examples: 50, 100, 200, 400, 800 l/min measured under specified pressure conditions).
• Hydraulic and mechanical tests
  • Nominal pressure (pN): 16 bar, test pressure (pt): 25.5 bar, burst pressure (pB): 50 bar - used for leak and burst verification.
  • Geodetic suction height requirement: (1.5 + 0.10) m.
  • Flow and proportioning tests are performed using standardized setups (outlet pressure p2 example: 6.5 bar at nominal flow).
• Proportioning performance
  • Inductors without setting device are fixed to a single marked proportion.
  • Inductors with setting device cover a range (typically 0.1% to 6%) with defined tolerances (e.g., ±10% or ±25% depending on range).
• Construction and components
  • Materials must resist foam concentrates and operating environments; special material choices (e.g., for marine use) should be agreed between manufacturer and purchaser.
  • Mandatory features: appropriate inlet/outlet connections, backflow preventer on foam inlet, direction arrow, pick‑up tube per EN 16712‑2, optional strainer (noting added pressure loss).
• Leakage and marking
  • Leak‑tightness tests: no more than a minimal leak (informative limit: up to 10 droplets/min) at test pressures.
  • Permanent marking and delivery with instruction and maintenance handbook (including maintenance, exploded diagrams and spare parts list).

Applications and users

• Practical use: field proportioning of foam concentrate for fire‑fighting operations supplied by fire pumps (land and potentially marine applications when materials agreed).
• Primary users:
  • Manufacturers of portable foam equipment and inductors
  • Fire and rescue services specifying or procuring foam induction gear
  • Testing bodies and conformity assessors performing type tests
  • Procurement/specification engineers and safety officers
