適用范圍：This International Standard specifies a method for the determination of the mass concentration of ni-trogen dioxide present in the air at work places (work areas or stationary posts) within the range of approximately, 1 rng/m3 to 50 mg/m3 using detector tubes.Substances which, if contained in the air mass under investigation and thus in the air sample, are known to have an effect on the instrument reading, are in-dicated in clause 5. Information on performance characteristics is given in 9.2; in applications re-quiring better precision or freedom from interfer-ences, the use of classical chemical or instrumental methods is recommended.The method is suitable for personal, breathing-zone sampling as well as for the general area sampling.
