DESCRIPTION

21/30427653 DC


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

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.

in air. The method is specific to formaldehyde but, with modification, at least 12 other aromatic as well as saturated and unsaturated aliphatic carbonyl compounds can be detected and quantified. It is suitable for determination of formaldehyde and other carbonyl compounds in the approximate concentration range 1 µg/m3 to 1 mg/m3. The sampling method gives a time-weighted average (TWA) sample. It can be used for long-term (1 h to 24 h) or short-term (5 min to 60 min) sampling of air for formaldehyde.

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[12],[16]. The method is not suitable for longer chained or unsaturated carbonyl compounds.

This part of ISO 16000 applies to the determination of:

acetaldehyde

acetone

benzaldehyde

butyraldehyde

capronaldehyde

2,5-dimethylbenzaldehyde

formaldehyde

isovaleraldehyde

propionaldehyde

m-tolualdehyde

o-tolualdehyde

p-tolualdehyde

valeraldehyde
