This European Standard provides the performance criteria and test procedures for filter dust monitors and filter leakage monitors used to ensure that dust arrestment plants used on stationary sources are working satisfactorily. A filter dust monitor is a dust arrestment plant monitor which can be calibrated in mass concentration units (e.g. mg/m3) and used for dust arrestment control purposes. A filter leakage monitor is a dust arrestment plant monitor which indicates a possible problem with the dust arrestment plant by monitoring a change in the emissions level or a change in the magnitude of the dust pulses created by the cleaning process. This standard is intended for use with the certification procedure for automated measuring systems described in EN 15267-1 and EN 15267-2.
