It covers waste water in all its forms, i.e. industrial waste water, radioactive waste water, cooling water, raw and treated domestic waste water.
It deals with various sampling techniques used and the rules to be applied so as to ensure the samples are representative.
Sampling of accidental spillages is not included, although the methods described in certain cases may also be applicable to spillages.

This part of ISO 5815 specifies the determination of the biochemical oxygen demand of waters by dilution and seeding with suppression of nitrification after 5 d incubation time.
This part of ISO 5815 is applicable to all waters having biochemical oxygen demands usually between 3 mg/l and 6 000 mg/l. It applies particularly to waste waters. For biochemical oxygen demands greater than 6 000 mg/l of oxygen, the method is still applicable, but the errors caused by the necessary dilutions can influence the analytical quality of the test method. Then the results are to be interpreted
with circumspection.
The results obtained are the product of a combination of biochemical and chemical reactions with participation by living matter which behaves only with occasional reproducibility. They do not have the rigorous and unambiguous character of those resulting from, for example, a single, well-defined, chemical process. Nevertheless, they provide an indication from which the quality of waters can be estimated.

ISO 20456:2017 applies to industrial electromagnetic flowmeters used for the measurement of flowrate of a conductive liquid in a closed conduit running full. It covers flowmeter types utilizing both alternating current (AC) and pulsed direct current (DC) circuits to drive the field coils and meters running from a mains power supply and those operating from batteries or other sources of power.
ISO 20456:2017 is not applicable to insertion-type flowmeters or electromagnetic flowmeters designed to work in open channels or pipes running partially full, nor does it apply to the measurement of magnetically permeable slurries or liquid metal applications.
ISO 20456:2017 does not specify safety requirements in relation to hazardous environmental usage of the flowmeter.

This European Standard specifies determination of the biochemical oxygen demand of waters of undiluted samples. This standard is applicable to all waters having biochemical oxygen demands greater than or equal to the limit of determination 0,5 mg/l of oxygen and not exceeding 6 mg/l of oxygen.

This document specifies a method for the determination of free chlorine and total chlorine in water,
readily applicable to lab- and field-testing. It is based on measurement of the absorption, the red DPD
colour complex in a photometer or the colour intensity by visual comparison of the colour with a scale
of standards that is regularly calibrated.
This method is appropriate for drinking water and other waters, where additional halogens like
bromine, iodine and other oxidizing agents are present in almost negligible amounts. Seawater and
waters containing bromides and iodides comprise a group for which special procedures are to be
carried out.
This method is in practice applicable to concentrations, in terms of chlorine (Cl2), from, for example,
0,000 4 mmol/l to 0,07 mmol/l (e.g. 0,03 mg/l to 5 mg/l) total chlorine. For higher concentrations, the
test portion is diluted.
Commonly, the method is applied as a field method with mobile photometers and commercially available
ready-for-use reagents (liquid reagents, powders and tablets). It is essential that those reagents comply
with minimum requirements and contain the essential reagents and a buffer system suitable to adjust
the measurement solution to a pH range of typically 6,2 to 6,5. If there is doubt that water samples
have uncommon pH values and/or buffer capacities, the user has to check and, if necessary, to adjust
the sample pH to the required range. The pH of the sample is within the range of pH 4 and 8. Adjust, if
necessary, with sodium hydroxide solution or sulfuric acid before the test.
A procedure for the differentiation of combined chlorine of the monochloramine type, combined
chlorine of the dichloramine type and combined chlorine in the form of nitrogen trichloride is
presented in Annex A. In Annex C, a procedure is presented for the determination of free and total
chlorine in drinking and other low polluted waters, for disposable planar reagent-filled cuvettes using a
mesofluidic channel pump/colorimeter.

This document defines the requirements for the use of rectangular and triangular (V-notch) thin-plate
weirs for the measurement of flow of clear water in open channels under free flow conditions. It includes
the requirements for the use of full-width rectangular thin-plate weirs in submerged (drowned) flow
conditions.

ISO/IEC 17025:2017 specifies the general requirements for the competence, impartiality and consistent operation of laboratories.
ISO/IEC 17025:2017 is applicable to all organizations performing laboratory activities, regardless of the number of personnel.
Laboratory customers, regulatory authorities, organizations and schemes using peer-assessment, accreditation bodies, and others use ISO/IEC 17025:2017 in confirming or recognizing the competence of laboratories.

This part of ISO 17294 specifies a method for the determination of the elements aluminium, antimony,
arsenic, barium, beryllium, bismuth, boron, cadmium, caesium, calcium, cerium, chromium, cobalt,
copper, dysprosium, erbium, gadolinium, gallium, germanium, gold, hafnium, holmium, indium, iridium,
iron, lanthanum, lead, lithium, lutetium, magnesium, manganese, mercury, molybdenum, neodymium,
nickel, palladium, phosphorus, platinum, potassium, praseodymium, rubidium, rhenium, rhodium,
ruthenium, samarium, scandium, selenium, silver, sodium, strontium, terbium, tellurium, thorium,
thallium, thulium, tin, tungsten, uranium and its isotopes, vanadium, yttrium, ytterbium, zinc and
zirconium in water (for example, drinking water, surface water, ground water, waste water and eluates).
Taking into account the specific and additionally occurring interferences, these elements can also be
determined in digests of water, sludges and sediments (for example, digests of water as described in
ISO 15587-1 or ISO 15587-2).
The working range depends on the matrix and the interferences encountered. In drinking water and
relatively unpolluted waters, the limit of quantification (xLQ) lies between 0,002 μg/l and 1,0 μg/l for
most elements. The working range typically covers concentrations between several pg/l
and mg/l depending on the element and pre-defined requirements.
The quantification limits of most elements are affected by blank contamination and depend
predominantly on the laboratory air-handling facilities available on the purity of reagents and the
cleanliness of glassware.
The lower limit of quantification is higher in cases where the determination suffers from interferences
or memory effects (see ISO 17294-1:2004, 8.2).

This International Standard provides guidelines on the principles of operation and the selection and use of
Doppler-based and echo correlation velocity meters for continuous-flow gauging.
This International Standard is applicable to channel flow determination in open channels and partially filled
pipes using one or more meters located at fixed points in the cross-section.

This part of ISO 9308 specifies a method for the enumeration of Escherichia coli (E. coli) and coliform
bacteria. The method is based on membrane filtration, subsequent culture on a chromogenic coliform
agar medium, and calculation of the number of target organisms in the sample. Due to the low selectivity
of the differential agar medium, background growth can interfere with the reliable enumeration of
E. coli and coliform bacteria, for example, in surface waters or shallow well waters. This method is not
suitable for these types of water.
This part of ISO 9308 is especially suitable for waters with low bacterial numbers that will cause less
than 100 total colonies on chromogenic coliform agar (CCA). These may be drinking water, disinfected
pool water, or finished water from drinking water treatment plants.
Some strains of E. coli which are β-D-glucuronidase negative, such as Escherichia coli O157, will not be
detected as E. coli. As they are β-D-galactosidase positive, they will appear as coliform bacteria on this
chromogenic agar.

This International Standard specifies a method for the determination of the acute toxicity to Daphnia magna Straus (Cladocera, Crustacea). This method is applicable to: - chemical substances which are soluble under the conditions of the test, or can be maintained as a stable suspension or dispersion under the conditions of the test; - industrial or sewage effluents; - treated or untreated waste water; - aqueous extracts and leachates; - fresh water (surface and ground water); - eluates of fresh water sediment; - pore water of fresh water sediment.

This part of ISO 10304 specifies a method for the determination of dissolved bromide, chloride, fluoride, nitrate, nitrite, orthophosphate and sulfate in water, e.g. drinking water, ground water, surface water, waste water, leachates and marine water by liquid chromatography of ions. The lower limit of application is ≥ 0,05 mg/l for bromide and for nitrite, and ≥ 0,1 mg/l for chloride, fluoride, nitrate, orthophosphate and sulfate. The lower limit application depends on the matrix and the interferences encountered. The working range may be expanded to lower concentrations (e.g. ≥ 0,01 mg/l) if an appropriate pre treatment of the sample (e.g. conditions for trace analyses, pre-concentration technique) is applied, and/or if an ultraviolet (UV) detector (for bromide, nitrate and nitrite) is used.

2010-08-31 EMA: //ENQ draft received in ISO/CS following notification received in dataservice on 2010-08-30.

ISO 7887:2011 specifies four different methods, designated A to D, for the examination of colour.
The previously most employed method for assessment of water colour in water treatment plants, limnological surveys, etc. was based on the hexachloroplatinate scale. Methods C and D are harmonized with this traditional procedure.
Method A involves examination of apparent colour by visually observing a water sample in a bottle. This gives only preliminary information, for example for use in field work. Only the apparent colour can be reported.
Method B involves determination of the true colour of a water sample using optical apparatus and is applicable to raw and potable water and to industrial water of low colour. A subclause on interferences is included.
Method C involves determination of the true colour of a water sample using optical apparatus for comparison with hexachloroplatinate concentration at wavelength, λ = 410 nm. A subclause on interferences is included.
Method D involves determination of colour by visual comparison with hexachloroplatinate standard solutions and can be applied to raw and drinking water. A subclause on interferences is included.
Methods A and B are appropriate if the colour hue of the sample differs from the hue of the matching solution.
When stating the result, the procedure used (methods A to D) is also recorded.

This part of ISO 18857 specifies a gas chromatographic-mass spectrometric (GC-MS) determination of selected alkylphenols, their ethoxylates and bisphenol A in non-filtered samples of drinking, ground, surface, and waste waters following solid-phase extraction and derivatisation. The lower limit of the working range depends on the matrix, on the specific compound to be analysed and on the sensitivity of the mass spectrometric detection unit. The method is applicable in a working range from 0,005 μg/l to 0,2 μg/l for 4-(1,1,3,3-tetramethylbutyl)phenol (OP), and its mono- (OP1EO) and diethoxylate (OP2EO), from 0,03 μg/l to 0,2 μg/l for 4-nonylphenol (mixture of isomers) (NP), and its mono- (NP1EO) and diethoxylate (NP2EO), and from 0,05 μg/l to 0,2 μg/l for bisphenol A (BPA). Depending on the matrix, the method is also applicable to waste water in a working range from 0,1 μg/l to 50 μg/l for OP, OP1EO, OP2EO and BPA, and from 0,5 μg/l to 50 μg/l for NP, NP1EO and NP2EO. The working ranges are based on experimental work carried out in ruggedness testing. Water samples containing suspended matter at concentrations of more than 500 mg/l and waste water samples are extracted by passing a 100 ml sample through the cartridge.

This International Standard defines a method for the determination of lipophilic substances of low volatility in water using gravimetry.
The method is applicable to all kinds of water and allows the determination of low-volatility lipophilic substances which are suspended, emulsified, or dissolved, in concentrations of about 10 mg/l to 500 mg/l.
Above this value, the test portion is diluted appropriately.
The method is not applicable to water with a separate oil layer.

This International Standard specifies a method for the determination of glyphosate and its major metabolite, aminomethylphosphonic acid (AMPA), in drinking water, ground water and surface water. The lowest limit of determination is about 0,05 µg/l. This method may be applicable to other types of waters provided the method is validated for each case.

This International Standard specifies a method for determining the pH value in rain, drinking and mineral waters, bathing waters, surface and ground waters, as well as municipal and industrial waste waters, and liquid sludge, within the range pH 2 to pH 12 with an ionic strength below I = 0,3 mol/kg (conductivity:  mS/m) solvent and in the temperature range 0 °C to 50 °C.

This International Standard specifies a method for the determination of dissolved elements, elements bound to particles ("particulate“) and total content of elements in different types of water (e.g. ground, surface, raw, potable and waste water) for the following elements:
Aluminium, antimony, arsenic, barium, beryllium, bismuth, boron, cadmium, calcium, chromium, cobalt, copper, gallium, indium, iron, lead, lithium, magnesium, manganese, molybdenum, nickel, phosphorus, potassium, selenium, silicon, silver, sodium, strontium, sulfur, tin, titanium, tungsten, vanadium, zinc and zirconium.
Taking into account the specific and additionally occurring interferences, these elements can also be determined in digests of water, sludges and sediments (for example digests of water as specified in ISO 15587 1 or ISO 15587 2). The method is suitable for mass concentrations of particulate matter in waste water below 2 g/l. The scope of this method may be extended to other matrices or to higher amounts of particulate matter if it can be shown that additionally occurring interferences are considered and corrected for carefully. It is up to the user to demonstrate the fitness for purpose.
Recommended wavelengths, limits of quantification and important spectral interferences for the selected elements are given in Clause 5 (Table 1).

This part of ISO 10304 specifies a method for the determination of dissolved bromide, chloride, fluoride, nitrate, nitrite, orthophosphate and sulfate in water, e.g. drinking water, ground water, surface water, waste water, leachates and marine water by liquid chromatography of ions. The lower limit of application is ≥ 0,05 mg/l for bromide and for nitrite, and ≥ 0,1 mg/l for chloride, fluoride, nitrate, orthophosphate and sulfate. The lower limit application depends on the matrix and the interferences encountered. The working range may be expanded to lower concentrations (e.g. ≥ 0,01 mg/l) if an appropriate pre treatment of the sample (e.g. conditions for trace analyses, pre-concentration technique) is applied, and/or if an ultraviolet (UV) detector (for bromide, nitrate and nitrite) is used.

CMC -  Incomplete superseding information

This part of ISO 18857 specifies a method for the determination of 4-nonylphenol (mixture of isomers) and 4-(1,1,3,3-tetramethylbutyl)phenol in non-filtered samples of drinking water, ground water and surface water. The method is applicable in a concentration range from 0,005 µg/l to 0,2 µg/l for 4-(1,1,3,3-tetramethylbutyl)phenol and from 0,02 µg/l to 0,2 µg/l for 4-nonylphenol (mixture of isomers). Depending on the matrix, the method is also applicable to waste water in a concentration range from 0,1 µg/l to 50 µg/l. Higher concentrations may be measured after appropriate dilution of the sample.

This European Standard describes a method for the determination of suspended solids in raw waters, waste waters and effluents by filtration through glass fibre filters. The lower limit of the determination is about 2 mg/l. No upper limit has been established. Water samples are not always stable which means that the content of suspended solids depends on storage time, means of transportation, pH value and other circumstances. Results obtained with unstable samples should be interpreted with caution.

This European standard specifies a method for the direct determination of an amount of more than 10 microgram/l in water of organically bound chlorine, bromine and iodine (expressed as chloride) adsorbable on activated carbon. The concentration of inorganic chloride ions in the test sample (see clause 8) needs to be less than 1 g/l. Samples with higher concentrations need to be diluted prior to analysis. For samples containing suspended solids, halogens adsorbed onto the solid matter are also included.

This European standard specifies methods for the determination of orthophosphate (see clause three); orthophosphate after solvent extraction (see clause four); hydrolysable phosphate plus orthophosphate (see clause five); total soluble phosphorus and total phosphorus after decomposition (see clauses six and seven). The methods are applicable to all kinds of water including seawater and effluents. Phosphorus contents within the range of 0,005 to 0,8 mg per litre may be determined in such samples without dilution.

ISO - Taking over of an ISO Technical Corrigendum

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.
