Soil quality. Physical methods. Assessment of the structural stability of a soil.

La présente norme expérimentale a pour objectif de classer les sols agricoles selon leurs capacités de résistance à des actions météoriques qui dégraderaient leur état structural. Elle comprend d'une part un test destiné à apprécier la résistance des agrégats à l'éclatement dû à leur humectation, d'autre part un test de percolation indicateur de la diminution potentielle de la conductivité hydraulique en milieu saturé. La méthode s'applique spécifiquement aux horizons de surface, intéressés par les façons culturales.

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!
