标准范围

This document 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 the volatile ammonia content of 
the waste gas.
This document specifies an independent method of measurement, which has been validated in field 
tests in a NH₃ concentration range of approximately 8 mg/m³ to 65 mg/m³ at standard conditions. The 
lower limit of the validation range was determined under operational conditions of a test plant. The 
measurement method can be used at lower values depending, for example, on the sampling duration, 
sampling volume and the limit of detection of the analytical method used.
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.
