Stationary source emissions. Determination of the mass concentration of dinitrogen monoxide (N2O). Reference method. Non-dispersive infrared method Ingestion-build-81111 BS ISO/TR 12885 will beBS EN ISO 21258: 2010 Stationary source emissions. Determination of the mass concentration of dinitrogen monoxide (N2O). Reference method. Non dispersive infrared method BS EN ISO 21258 is an International Standard which specifies a method for sampling, sample conditioning and determination of dinitrogen monoxide (N2O) content in the flue gas emitted from ducts and stacks to atmosphere. It sets out the non dispersive infrared (NDIR) analytical
