NBN ISO 16000-23:2021

This document 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 compounds, i.e. formaldehyde and other carbonyl compounds, can be brought
about by adsorption, absorption and chemisorption.
The method specified in this document employs formaldehyde and other carbonyl compound spiked
supply air to determine the performance of building materials in reducing formaldehyde and other
carbonyl compounds concentrations.
This document 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 document applies to the determination of formaldehyde and other carbonyl compounds,
such as formaldehyde, acetaldehyde, acetone, benzaldehyde, butyraldehyde, valeraldehyde,
2,5-dimethylbenzaldehyde, capronaldehyde, isovaleraldehyde, propionaldehyde, o-tolualdehyde,
m-tolualdehyde, p-tolualdehyde.
