Intermediate chamber
The Loss Prevention Certification Board (LPCB part of BRE Global) sets the standards needed to ensure that fire and security products and services perform effectively. LPCB’s Loss Prevention Standards (LPS) are applied in fire and security sectors around the world.
LPS 1041 – 1.3, Requirements and testing procedures for the LPCB approval and listing of dry pipe valve sets, published by BRE Global in 2014, defines an intermediate chamber as: ‘That portion of a dry pipe valve which separates the air/or water sealing assembly seating surfaces and which is at atmospheric pressure when the valve is in the ready position.’
