Fertilizers and soils conditioners. Determination of magnesium by atomic absorption spectrometric method.

La présente norme a pour objet de fixer une méthode de dosage de l'oxyde de magnésium (MgO) dans les matières fertilisantes définies dans les normes de dénominations et spécifications. Ce dosage est pratiqué sur une solution provenant de l'attaque ou de l'extraction de ces matières fertilisantes par des réactifs appropriés (par exemple après attaque chlorhydrique selon NF U 44-140). La présente norme est applicable aux matières fertilisantes ayant une teneur en oxyde de magnésium (MgO) inférieure à 15 %, en pourcentage en masse.

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.

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