|Standard number:||21/30427653 DC|
|Status:||Draft for Comment|
This standard 21/30427653 DC BS ISO 16000-3. Indoor air is classified in these ICS categories:
- 13.040.20 Ambient atmospheres
This part of ISO 16000 specifies a determination of formaldehyde (HCHO) and other carbonyl compounds (aldehydes and ketones)1
Instead of systematic IUPAC nomenclature, traditional names are used in this part of ISO 16000. Some equivalent names are: acetaldehyde: ethanal / acetone: 2-propanone / butyraldehyde: butanal / capronaldehyde: hexanal / formaldehyde: methanal / isovaleraldehyde: 3-methylbutanal / propionaldehyde: propanal / m-tolualdehyde: 3-methylbenzaldehyde / o-tolualdehyde: 2-methylbenzaldehyde / p-tolualdehyde: 4-methylbenzaldehyde / valeraldehyde: pentanal.
This part of ISO 16000 specifies a sampling and analysis procedure for formaldehyde and other carbonyl compounds that involves collection from air on to adsorbent cartridges coated with 2,4-dinitrophenylhydrazine (DNPH) and subsequent analysis of the hydrazones formed by high performance liquid chromatography (HPLC) with detection by ultraviolet absorption,. The method is not suitable for longer chained or unsaturated carbonyl compounds.
This part of ISO 16000 applies to the determination of:
