NF ISO 16000-3
Indoor air - Determination of formaldehyde and other carbonyl compounds in indoor air and test chamber air - Part 3 : Active sampling method
This part of ISO 16000 specifies a determination of formaldehyde (HCHO) and other carbonyl compounds (aldehydes and ketones) 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 (see last paragraph) 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. This part of ISO 16000 applies to the determination of: formaldehyde; acetaldehyde; acetone; benzaldehyde; butyraldehyde; valeraldehyde; 2,5-dimethylbenzaldehyde; capronaldehyde; isovaleraldehyde; propionaldehyde; o-tolualdehyde; m-tolualdehyde; p-tolualdehyde.

<p> La présente partie de l'ISO 16000 décrit un mode opératoire pour le dosage du formaldéhyde (HCHO) et d'autres composés carbonylés (aldéhydes et cétones) dans l'air. Cette méthode est spécifique au formaldéhyde, mais avec quelques modifications, il est possible de détecter et quantifier au moins treize autres composés carbonylés. Elle s'applique au dosage du formaldéhyde et d'autres composés carbonylés dans la plage de concentrations comprise entre environ 1 µg/m3 et 1 mg/m3. La méthode d'échantillonnage donne un résultat moyen pondéré dans le temps. Elle se prête à l'échantillonnage du formaldéhyde dans l'air à long terme (1 h à 24 h) ou à court terme (5 min à 60 min). La présente partie de l'ISO 16000 décrit un mode opératoire d'échantillonnage et d'analyse pour le formaldéhyde et d'autres composés carbonylés qui implique un prélèvement de l'air sur des cartouches imprégnées de 2,4-dinitrophénylhydrazine (DNPH) et une analyse ultérieure par chromatographie en phase liquide à haute performance (HPLC) avec détection par absorption ultraviolette. Les modes opératoires décrits sont rédigés spécifiquement pour l'échantillonnage et l'analyse du formaldéhyde contenu dans l'air à l'aide de cartouches adsorbantes et de la chromatographie en phase liquide à haute performance. Cette méthode permet également de doser d'autres aldéhydes et cétones prélevés dans l'air. </p>

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.
The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
