Water quality - Determination of metal content - Method for the measurement of metal concentration with passive sampling by diffusive gradient in thin films

Le présent document spécifie un mode opératoire pour la mesure de certains cations métalliques (par exemple cadmium, cobalt, cuivre, fer, manganèse, nickel, plomb et zinc) dans les eaux, après préconcentration de ces cations sur un dispositif d'échantillonnage passif par gradient diffusif en couche mince. Compte tenu des éléments visés, la résine considérée est de type chélatant, permettant principalement un piégeage des cations métalliques di ou trivalents en solution. D'autres outils basés sur d'autres types de résine permettant de piéger d'autres éléments peuvent être utilisés.

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

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.

With Requirements, quickly access the main part of the normative text!
