DIN EN 16020:2011-10

An explosion diverter is used to divert explosions propagating through ducts. The device is used to prevent flame jet ignition and pressure piling in connected protected enclosures. It will reduce the risk of flame transmission. This document describes the basic design of a pipe-in-pipe diverter and specifies the testing requirements and the application of explosion diverters. It covers a test method for assessing the efficacy of explosion diverters, design rules for a type of pipe-in-pipe diverter, demands to venting device on the diverter, installation and maintenance requirements and marking. This document considers dust/air explosive atmospheres only.
