Water quality - Determination of turbidity - Part 2: Semi-quantitative methods for the assessment of transparency of waters (ISO 7027-2:2019)

This document specifies the following semi-quantitative methods for the assessment of transparency of waters:
a)    measurement of visual range using the transparency testing tube (applicable to transparent and slightly cloudy water),  see Clause 4;
b)    measurement of visual range in the upper water layers using the transparency testing disc (especially applicable to surface, bathing water, waste water and often used in marine monitoring), see 5.1;
c)    measurement of visibility by divers in a destined depth, see 5.2.
NOTE       The quantitative methods using optical turbidimeters or nephelometers are described in ISO 7027-1.

Wasserbeschaffenheit - Bestimmung der Trübung - Teil 2: Semi-quantitative Verfahren zur Beurteilung der Lichtdurchlässigkeit (ISO 7027-2:2019)

Dieses Dokument legt die folgenden semi quantitativen Verfahren für die Beurteilung der Transparenz von Gewässern fest:
a)   Messung der Sichtweite mithilfe des Transparenzprüfröhrchens (anwendbar für klares und leicht getrübtes Wasser), siehe Abschnitt 4;
b)   Messung der Sichtweite der oberen Wasserschichten mithilfe der Sichtscheibe (speziell anwendbar für Oberflächengewässer, Badegewässer, Abwässer und oftmals in der Überwachung im maritimen Bereich), siehe 5.1;
c)   Messung der Sichtweite mittels Sichtscheibe durch Taucher in einer vorgesehenen Tiefe, siehe 5.2.
ANMERKUNG   Die quantitativen Verfahren unter Verwendung optischer Trübungsmessgeräte oder Nephelometer sind in ISO 7027 1 beschrieben.

Kakovost vode - Ugotavljanje motnosti - 2. del: Semikvantitativne metode za ocenjevanje prosojnosti vode (ISO 7027-2:2019)

Ta dokument določa naslednje semikvantitativne metode za ocenjevanje prosojnosti
vode:
a) merjenje vidnega območja z uporabo epruvete za preskušanje prosojnosti (uporablja se za prosojno in
rahlo motno vodo), glej točko 4;
b) merjenje vidnega območja v zgornjih slojih vode z uporabo diska za preskušanje prosojnosti
(uporablja se zlasti za površinsko, kopalno in odpadno vodo ter pogosto pri monitoringu morja),
glej točko 5.1;
c) merjenje vidljivosti, ki ga izvedejo potapljači na predvideni globini, glej točko 5.2.
OPOMBA: Kvantitativne metode z uporabo optičnih turbidimetrov ali nefelometrov so opisane v standardu ISO 7027-1.
