DANSK DSF/ISO/FDIS 16000-23 PDF

This part of ISO 16000 specifies a general laboratory test method for evaluating the reduction of formaldehyde and other carbonyl compounds (aldehydes and ketones) concentrations by sorptive building materials. This method applies to boards, wallpapers, carpets, paint products, and other building materials. The sorption of those target compound(s), i.e. formaldehyde and other carbonyl compounds can be brought about by adsorption, absorption and chemisorption. The performance of the material with respect to its ability to reduce the concentration of formaldehyde and other carbonyl compounds in indoor air is evaluated by measuring area specific reduction rate and saturation mass per area. The former directly indicates material performance with respect to formaldehyde and other carbonyl compounds concentration reduction at a point in time; the latter relates to the ability of a product to maintain that performance. The method specified in this part of ISO 16000 employs formaldehyde and other carbonyl compounds -spiked supply air to determine the performance of building materials in reducing formaldehyde and other carbonyl compounds concentrations. This part of ISO 16000 is based on the test chamber method specified in ISO 16000-9. Sampling, transport and storage of materials to be tested and preparation of test specimens are specified in ISO 16000-11. Air sampling and analytical methods for the determination of formaldehyde and other carbonyl compounds are specified in ISO 16000-3, which is part of the complete procedure. This part of ISO 16000 applies to the determination of formaldehyde and other carbonyl compounds, e.g., formaldehyde; acetaldehyde; acetone; benzaldehyde; butyraldehyde; valeraldehyde; 2,5-dimethylbenzaldehyde; capronaldehyde; isovaleraldehyde; propionaldehyde; o-tolualdehyde; m-tolualdehyde; p-tolualdehyde.
