JIS B 7993:2008 PDF

Scope: This Japanese Industrial Standard specifies the automated measuring systems (hereafter referred to as "measuring system") installed in situ which perform the long-term continuous measurement of the concentration of sulfur dioxide, nitrogen monoxide, dinitrogen monoxide, nitrogen dioxide, carbon monoxide, carbon dioxide. ammonia, hydrogen chloride, methane and moisture in the gas discharged with com- bustion of fuel and others or from various manufacturing processes etc. to a chimney or a duct in a factory and a business place using non-extractive methods. The measurement principle of this Standard shall be based on an infrared absorption method and an ultraviolet absorption method. As other measuring systems, the meas- uring system by a point method (fixed-point measurement) is given in Annex C. NOTE: The following International Standards are used as reference in this Standard. ISO 7935: 1992 Stationary source emissions- Determination of the mass concentration of su]~ur dioxide- Per~ormance characteristics of automated measuring methods ISO 10849: 1996 Stationary source emissions- Determination of the mass concentration of nitrogen oxides--Per~ormance characteristics o[' automated measuring systems
