Resumen:
Formaldehyde has a high potential toxicity, and therefore, its determination is of special interest as an indoor air pollutant. This part of ISO 16000 specifies a diffusive sampler/solvent desorption/high performance liquid chromatography (HPLC) method for the determination of formaldehyde in indoor air. Following this procedure the sampling strategy described in ISO 16000-2 is to be taken into account. The method is suitable for measurements in atmospheres with conventional indoor air 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. The test method is applicable to the measurement of formaldehyde in indoor air over the range from 0,001 mg/m<(hoch)3> to 1,0 mg/m<(hoch)3> 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<(hoch)3> to 1 mg/m<(hoch)3>, and for 72 h it is 0,001 mg/m<(hoch)3> to 0,33 mg/m<(hoch)3>. Confirmed samplers with respect to measurement sensitivity and precision may apply to short-term sampling of less than 24 h. Formaldehyde is the simplest carbonyl compound, with one carbon, one oxygen and two hydrogen atoms. In its monomolecular state, it is a colourless, pungent, reactive gas. It has been used in the production of urea-formaldehyde resins, adhesives and insulating foams. Emissions from particle (chip) board and wall insulation are the major sources of formaldehyde in indoor air.
