This European Standard specifies a method for measuring the sand rejection efficiency of sand trap louvres subject to simulated sand and with inlet air flow through the louvre under test. The Standard considers a 1000 mm ´ 1000 mm section of sand trap louvre, or the nearest possible blade increment, for evaluation purposes.The purpose of the tests incorporated in this European Standard is as follows:a) Sand Rejection EffectivenessTo establish the sand rejection effectiveness when subjected to various air flow rates through the assembly.b) Entry loss coefficient/Pressure requirementsTo establish the air pressure loss through the sand trap louvre at various air flow rates and by calculation Discharge Loss Coefficient.
