Defines generic method for the determination and the reporting of time averaged mass emissions from a specific installation or of a family of installations (or common source type), using data collected by measurements, and by establishing: - mass emission rates by the simultaneous measurement of concentration and gas flow, using standardized manual or automatic methods, and also the estimation of the uncertainty of the measurements; - time-averaged mass emission rates using time series of mass emission rate values, their uncertainty characteristics, and also the determination of the expanded uncertainty of the average; - time-averaged emission factors for a specific installation or of a family of installations and their associated uncertainty characteristics; - a quality management system to assist the process of inventory quality assurance and verification.
