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

Water quality - Determination of turbidity - Part 1: Quantitative methods (ISO 7027-1:2016)
SIST EN ISO 7027-1:2017

ISO 7027-1:2016 specifies two quantitative methods using optical turbidimeters or nephelometers for the determination of turbidity of water:
a)    nephelometry, procedure for measurement of diffuse radiation, applicable to water of low turbidity (for example drinking water);
b)    turbidimetry, procedure for measurement of the attenuation of a radiant flux, more applicable to highly turbid waters (for example waste waters or other cloudy waters).
Turbidities measured according to the first method are presented as nephelometric turbidity units (NTU). The results typically range between <0,05 NTU and 400 NTU. Depending on the instrument design, it can also be applicable to waters of higher turbidity. There is numerical equivalence of the units NTU and formazin nephelometric unit (FNU).
Turbidity measured by the second method is expressed in formazin attenuation units (FAU), results typically range between 40 FAU and 4 000 FAU.

Water quality - Determination of total cyanide and free cyanide using flow analysis (FIA and CFA) - Part 2: Method using continuous flow analysis (CFA) (ISO 14403-2:2012)
SIST EN ISO 14403-2:2013

ISO 14403-2:2012 specifies methods for the determination of cyanide in various types of water (such as ground, drinking, surface, leachate, and waste water) with cyanide concentrations usually from 2 µg/l to 500 µg/l expressed as cyanide ions in the undiluted sample. The range of application can be changed by varying the operation conditions, e.g. by diluting the original sample or changing the pathlength of the flow cell.
In this method, a suitable mass concentration range from10 µg/l to 100 µg/l is described.
Seawater can be analysed with possible changes in sensitivity and adaptation of the reagent and calibration solutions to the salinity of the samples.

SIST EN ISO 14403-1:2013

ISO 14403-1:2012 specifies methods for the determination of cyanide in various types of water (such as ground, drinking, surface, leachate, and waste water) with cyanide concentrations from 2 µg/l to 500 µg/l expressed as cyanide ions in the undiluted sample.

In ISO 14403-1:2012, a suitable mass concentration range from 20 µg/l to 200 µg/l is described.
Seawater can be analysed with possible changes in sensitivity and adaptation of the reagent and calibration solutions to the salinity of the samples.

SIST EN ISO 15839:2007

ISO 15839:2003 describes the performance testing of on-line sensors/analysing equipment for water. The standard is applicable to most sensors/analysing equipment, but it is recognized that, for some sensors/analysing equipment, certain performance tests cannot be carried out. This International Standard
defines an on-line sensor/analysing equipment for water quality measurements;defines terminology describing the performance characteristics of on-line sensors/analysing equipment;specifies the test procedures (for laboratory and field) to be used to evaluate the performance characteristics of on-line sensors/analysing equipment.

Water quality - Evaluation of ultimate aerobic biodegradability of organic compounds in aqueous medium - Static test (Zahn-Wellens method) (ISO 9888:1999)
SIST EN ISO 9888:2000

This International Standard specifies a method for the evaluation in aqueous medium of the ultimate
biodegradability and, as additional information, the primary biodegradability and the total elimination from water, of
organic compounds at a given concentration by aerobic microorganisms.
The conditions described in this International Standard normally correspond to optimal conditions for allowing the
maximum value of biodegradation to occur with the chosen inoculum in the test time. These conditions may even be
more favourable than in full-scale wastewater treatment plants, especially if their hydraulic retention time, sludge
age or the adaptation of the activated sludge is not optimal.
The method applies to organic compounds which are
a) water-soluble at the concentration used under the test conditions and not expected to be transformed to
insoluble metabolites if biodegradation and not elimination only shall be determined;
b) nonvolatile, or which have a negligible vapour pressure under the test conditions;
c) not lost by foaming from the test solution;
d) not inhibitory to the test microorganisms at the concentration chosen for the test. Inhibitory effects can be
determined using a suitable test method (e.g. see ISO 8192). If the test compound is toxic, the test
concentration must be lowered, or a pre-exposed inoculum can be used.
This International Standard is also applicable to the measurement of biodegradation and elimination of dissolved
organic compounds in wastewater (also called "test compound" in the method).
NOTE If more information is required to predict the behaviour of test compounds or wastewater in a treatment plant, a
simulation test (e.g. the activated sludge simulation test ISO 11733) should be performed. For appropriate use of this method
and for alternative biodegradation methods, see ISO 15462.
