Le présent document spécifie une méthode pour déterminer la vitesse et l''efficacité du potentiel de neutralisation des carbonates de calcium, carbonates de calcium et de magnésium et silicates de calcium et de magnésium utilisés comme amendements minéraux basiques, par titrage potentiométrique à l''acide chlorhydrique. La présente méthode s''applique seulement aux amendements minéraux basiques dont la taille des particules ne dépasse pas 6,3 mm. Le type d''amendement minéral basique doit être identifié conformément à la NF EN 14069 et la taille des particules doit être déterminée conformément à la NF EN 12948.

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!


What is the Redline format?
The Redline + service - standards comparator allows you to easily and simply identify major changes between the current standard and its last canceled version.

At a glance, you will be able to identify the additions, deletions or modifications to a text, table, figure and formula.


The Redlines + service is offered to you on the collection of French standards in force, in French language and in HTML and PDF format.
