This European Standard specifies the conversion of raw data from an automated measuring system (AMS) to reported data by a data acquisition and handling system (DAHS). This specification includes:

—    requirements for the handling of data;

—    requirements for the reporting of data;

—    calculation procedures required.

The main items covered by this European Standard are given by, but not limited to raw data acquisition, raw data validation, data correction and data averaging.

This European Standard supports the requirements of EN 14181 and legislation such as the IED and E-PRTR. It does not preclude the use of additional features and functions provided the minimum requirements of this European Standard are met and that these features do not adversely affect data quality, clarity or access.

This International Standard specifies a manual method of measurement including sampling and different analytical methods for the determination of the mass concentration of ammonia (NH3) in the waste gas of industrial plants, for example combustion plants or agricultural plants. All compounds which are volatile at the sampling temperature and produce ammonium ions upon dissociation during sampling in the absorption solution are measured by this method, which gives therefore the volatile ammonia content of the waste gas.

This International Standard specifies an independent method of measurement, which has been validated in field tests up to a NH3 concentration of approximately 65 mg/m3 at standard conditions.

NOTE 1       The plant, the conditions during field tests and the performance characteristics obtained in the field are given in Annex A.

This method of measurement can be used for intermittent monitoring of ammonia emissions as well as for the calibration and validation of permanently installed automated ammonia measuring systems.

NOTE 2       An independent method of measurement is called standard reference method (SRM) in EN 14181.
