Soil : investigation and testing - Lefranc test

Le présent document définit la terminologie, spécifie les conditions de préparation de l'essai et les caractéristiques de l'appareillage. Il fixe le mode opératoire à suivre pour réaliser un essai d'eau Lefranc et précise la présentation des résultats. Cet essai, applicable à tous les sols fins ou grenus sous la nappe, est un moyen de reconnaissance du terrain en place et permet d'évaluer une caractéristique hydraulique du sol par la détermination d'un coefficient de perméabilité locale, dit coefficient de perméabilité Lefranc.

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.
