Hydrometry - Measurement requirements and classification of rainfall intensity measuring instruments

This document considers liquid atmospheric precipitation and defines the procedures and equipment to perform laboratory and field tests, in steady-state conditions, for the calibration, check and metrological confirmation of liquid precipitation measurement instruments. It provides a classification of catching-type measurement instruments based on their laboratory performance. The classification does not relate to the physical principle used for the measurement, nor does it refer to the technical characteristics of the instrument assembly, but is solely based on the instrument calibration. Attribution of a given class to an instrument is not intended as a high/low ranking of its quality but rather as a quantitative standardized method to declare the achievable measurement accuracy in order to provide guidance on the suitability for a particular purpose, while meeting the user’s requirements.

Hydrometrie - Messbedingungen und Klassifizierung von Geräten zur Messung der Regenintensität

Dieses Dokument berücksichtigt flüssigen atmosphärischen Niederschlag und legt Verfahren und Ausrüstung zur Durchführung von Labor  und Feldprüfungen unter stationären Bedingungen für die Kalibrierung, Prüfung und metrologische Bestätigung von Geräten zur Messung von flüssigem Niederschlag fest. Es enthält eine Klassifizierung von Messgeräten mit Auffangvorrichtung, basierend auf ihrer Leistung im Labor. Die Klassifizierung bezieht sich weder auf das für die Messung verwendete physikalische Prinzip noch auf die technischen Eigenschaften der Gerätebaugruppe, sondern basiert alleine auf der Gerätekalibrierung. Die Zuordnung einer bestimmten Klasse zu einem Gerät ist nicht als Einstufung der Qualität in hochrangig oder niederrangig vorgesehen, sondern eher als quantitatives standardisiertes Verfahren, um die erreichbare Messgenauigkeit anzugeben und somit Leitlinien zur Eignung für einen bestimmten Zweck zu geben und gleichzeitig die Anforderungen des Nutzers zu erfüllen.

Hydrométrie - Exigences de mesure et classification des instruments de mesure d'intensité pluviométrique

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.

Hidrometrija - Merilne zahteve in razvrstitev instrumentov za merjenje moči padavin

Ta standard obravnava tekoče padavine in določa razvrstitev instrumentov za merjenje moči padavin s posodo za zbiranje padavin na podlagi usposobljenosti laboratorija. Standardizirani preskusi umerjanja so opisani za oceno točnosti teh naprav za merjenje količine padavin v laboratoriju in na terenu. Razvrstitev ni povezana s fizikalnim načelom, ki se uporablja za merjenje, prav tako se ne navezuje na tehnične lastnosti sestava merilnih instrumentov. Razvrstitev temelji izključno na točnosti umerjanja naprave za merjenje moči padavin.
