SIS SS-ISO 8761:1990 Work-place air — Determination of mass concentration of nitrogen dioxide — Method using detector tubes for short- term sampling with direct indication
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.
