BS EN 13284-1:2017EN 13284-1:2017 (E) 5 1 Scope This European Standard specif

34、ies the standard reference method (SRM) for the measurement of low dust concentration in ducted gaseous streams in the concentrations below 50 mg/m3at standard conditions. This European Standard is primarily developed and validated for gaseous streams emitted by waste incinerators. More generally, i

35、t can be applied to gases emitted from other stationary sources, and to higher concentrations. If the gases contain unstable, reactive or semi-volatile substances, the measurement depends on the sampling and filter treatment conditions. This method has been validated in field tests with special emph

36、asis to dust concentrations around 5 mg/m3. The results of the field tests are presented in Annex A. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
