Liming materials - Determination of size distribution by dry and wet sieving

Le présent document décrit deux méthodes pour déterminer la distribution granulométrique des amendements minéraux basiques. La méthode de tamisage à sec (méthode A) est applicable à tous les amendements minéraux basiques, à l'exception des produits humides ou pâteux. La méthode de tamisage à l'état humide (méthode B) est applicable aux produits qui sont susceptibles de colmater le tamis, de s'agglutiner, de provoquer des charges électrostatiques ou de s'agglomérer lors du préséchage.

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.
