Plant Biostimulants - Determination of specific elements - Part 1 : digestion by aqua regia for subsequent determination of elements

Le présent document spécifie ma méthode pour la digestion de différents biostimulants des végétaux à l'eau régale pour permettre le dosage ultérieur de l'arsenic (As) , du cadmium (Cd) , du cuivre (Cu) , du chrome (Cr) , du mercure (Hg) , du nickel (Ni) , du plomb (Pb) et du zinc (Zn). Cette méthode peut aussi être appliquée pour le dosage d'autres éléments. Il est applicable à tous les biostimulants des végétaux solides et/ou liquides. Le présent document est également applicable aux mélanges de fertilisants dont la majeure partie est constituée de biostimulants des végétaux. Dans le cas contraire, la Spécification technique relative au constituant principal du mélange s'applique. Les extraits conviennent pour une analyse selon la XP CEN/TS 17701-2 (ICP-AES) et la XP CEN/TS 17701-3 (analyse du Hg). Il est également possible d'utiliser la spectrométrie de masse avec plasma à couplage inductif (ICP-MS) pour la mesure, si l'utilisateur prouve que la méthode conduit aux mêmes résultats.

ZOOM ON ... the Requirements department
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.
