Eurovent 2/6: Laboratory testing and rating of sand trap louvres when subjected to simulate sand

This document specifies a method for measuring the sand rejection efficiency of sand trap louvres, subject to simulated sand and with air flow through the louvre under test. For the purpose of this test, a 1000 mm x 1000 mm section of sand trap louvre or the nearest possible blade increment is to be tested. This document is available in English.
