Hydrometry - Measurement requirements and classification of rainfall intensity measuring instruments

Le présent document couvre les précipitations atmosphériques liquides et définit les modes opératoires et l'équipement permettant d'effectuer des essais en laboratoire et sur le terrain, dans des conditions stables, pour l'étalonnage, le contrôle et la confirmation métrologique des instruments de mesure des précipitations liquides. Il fournit une classification des pluviomètres collecteurs d'après leurs performances en laboratoire. La classification ne concerne ni le principe physique utilisé pour le mesurage, ni les caractéristiques techniques de l'ensemble de l'instrument, mais uniquement l'étalonnage de l'instrument. L'attribution d'une classe à un instrument n'est pas destinée à servir de classement de sa qualité mais plutôt de méthode quantitative normalisée pour déclarer l'exactitude de mesure atteignable afin de fournir des recommandations sur l'adéquation avec un objectif particulier, tout en satisfaisant aux exigences de l'utilisateur.

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!
