This document supports the elaboration of standardized measurement methods for the determination of stationary source emissions by manual or automated measurement methods. This document describes the basic elements of standardized measurement methods for the determination of stationary source emissions. This document is supplemented by an electronic template providing a uniform structure and common elements and texts. NOTE Detailed information on the electronic template is given in Annex A. This document is addressed to working groups of CEN/TC 264 dealing with stationary source emissions. It aims at facilitating in the working groups the elaboration and the harmonization of documents produced by CEN/TC 264. Such documents can be European standards (EN), European Technical Specifications (CEN/TS) or European Technical Reports (CEN/TR).
