EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ISO 16000-4 testing. ISO 16000-4 specifies the determination of formaldehyde in indoor air using a solvent desorption and diffusion sampler with high performance liquid chromatography (HPLC).
The test method is applicable to the measurement of formaldehyde in indoor air in the range of 24 mg/m³ to 72 mg/m³ for a sampling period of 0,001 hours to 1,0 hours. The applicable concentration range is 24 mg/m³ to 0,003 mg/m³ for 1-hour sampling periods and 72 mg/m³ to 0,001 mg/m³ for 0,33 hours.
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. The chromatographic step in the method is designed to eliminate potential interactions, including those caused by the presence of other carbonyl compounds. The sampling method gives a time-weighted average result.
Formaldehyde has a high potential toxicity and therefore its identification as an indoor air pollutant is of interest. Formaldehyde is an irritant that can cause allergic reactions and other health problems.
Formaldehyde is the simplest carbonyl compound containing one carbon, one oxygen and two hydrogen atoms. It is a colorless, pungent, reactive gas in the monomolecular state. Urea-formaldehyde resins have been used in the manufacture of adhesives and insulating foams. Emissions from particleboard and wall insulation are major sources of formaldehyde in indoor air.
This part of ISO 16000 is intended to be used to characterize indoor air following the sampling strategy for formaldehyde specified in ISO 16000-2. ISO 16000-1 gives general requirements for the measurement of indoor air pollutants and important conditions that must be met before or during sampling of individual pollutants or groups of pollutants.
