标准简介：This part of IS0 16000 specifies a diffusive sampler/solvent desorption/high performance liquid chromatography (HPLC) method for the determination of formaldehyde in indoor air.
The test method is applicable to the measurement of formaldehyde<up1)> in indoor air over the range from 0,001 mg/m<up3> to 1,0 mg/m<up3> for a sampling period of between 24 h and 72 h. For sampling periods of 24 h, the applicable concentration range is 0,003 mg/m<up3> to 1 mg/m<up3>, and for 72 h it is 0,001 mg/m<up3> to 0,33 mg/m<up3>.
The method is suitable for measurements in atmospheres of up to 80 % relative humidity and for monitoring at air velocities as low as 0,02 m/s. Potential interferences, including those due to the presence of other carbonyl compounds, should be eliminated by the chromatographic step in the method. The sampling method gives a time-weighted average result.
note: 1) Instead of the nomenclature according to IUPAC regulations (e.g. methanal), the more common names (e.g. formaldehyde) are used in this part of ISO 16000.
