Dieser Teil von ISO 7027 legt zwei quantitative Verfahren unter Verwendung von optischen Trübungsmessgeräten oder Nephelometern zur Bestimmung der Trübung von Wasser fest: a) Nephelometrie: Verfahren zur Messung der an Partikeln gestreuten Strahlung (Streustrahlung), anwendbar auf Wasser mit geringer Trübung (z. B. Trinkwasser); b) Turbidimetrie: Verfahren zur Messung der Schwächung der durchgehenden Strahlung. Sie sind besser geeignet für stark trübe Wässer (z. B. Abwässer oder schwebstoffhaltige Wässer). Nach dem ersten Verfahren gemessene Trübungen werden in nephelometrischen Trübungs-Einheiten (NTU, en: nephelometric turbidity unit) angegeben. Ergebnisse liegen typischerweise zwischen < 0,05 NTU und 400 NTU. In Abhängigkeit vom Geräteaufbau können auch stärker getrübte Wässer gemessen werden. Es besteht eine zahlenmäßige Gleichheit der Einheiten NTU und Formazin-nephelometrische Einheit (FNU, en: formazine nephelometric units). Nach dem zweiten Verfahren gemessene Trübungen werden in Formazin-Schwächungseinheiten (FAU, en: formazin attenuation units) angegeben; die Ergebnisse liegen typischerweise zwischen 40 FAU und 4000 FAU.

5.1 Technetium-99 is produced by the fission of uranium and plutonium, and has been released to the environment via nuclear weapons testing and nuclear materials processing. In an oxidizing environment, it exists as the very mobile pertechnetate ion, TcO4–, which is an analog to nitrate and can be taken up by living organisms. Monitoring of 99Tc in waters around nuclear processing facilities is part of a complete environmental monitoring program. 5.2 Technetium-99 is a long-lived (half-life 2.1E+5years), weak beta (maximum beta energy of 293 keV) emitting radioisotope. There are no stable isotopes of Tc. Thus the determination of its activity concentration presents unique challenges to traditional radiochemical determination methods. This method provides an alternative to the spiked/unspiked replicate method of Method D7168 and uses options presented in Guide C1387 for the determination of 99Tc in soil. 1.1 Technetium is separated and concentrated from a water sample by extraction chromatography using its chemical analog, rhenium, as a tracer. The ratio of technetium to rhenium is measured by inductively coupled plasma mass spectrometry (ICP-MS) to then quantify the 99Tc concentration. 1.1.1 This practice is provided as an alternative to Test Method D7168 which provides for a different separation media geometry and measurement by liquid scintillation spectrometry. Similar detection limits should be attainable by this method. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

1.1 This practice describes continuous sample conditioning by hydrogen ion exchange and measurement by electrolytic conductivity. It is commonly known as cation conductivity measurement in the power industry although it is actually an indication of anion contamination in high purity water samples. Measurements are typically in a range less than 1 µS/cm. 1.2 The actual conductivity measurements are made using Test Method D5391. 1.3 This practice does not provide for separate determination of dissolved carbon dioxide. Refer to Test Method D4519. 1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use.

This International Standard specifies a test method for measuring actinides (238Pu, 239+240Pu, 241Am, 242Cm, 243+244Cm and 237Np) in water samples by alpha spectrometry following a chemical separation. The method can be used for any type of environmental study or monitoring. The volume of the test portion required depends on the assumed activity of the sample and the desired detection limit. The detection limit of the test method is 5 × 10−3 to 5 × 10−4 Bq/l for a volume of the test portion of0,1 l to 5 l with a counting time of two to ten days.

This International Standard 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 (Reference [1]). Methods C and D are harmonized with this traditional procedure (References [2][3]). 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. NOTE 1 Under certain circumstances, strongly coloured water samples require dilution before examination or determination. However, this can alter the physical-chemical conditions leading to a change in colour. NOTE 2 An internal quality control procedure for all methods specified in this International Standard is given in Annex A. Precision data are given in Annex B. When stating the result, the procedure used (methods A to D) is also recorded.

Diese Internationale Norm legt die Bedingungen für die Bestimmung der Aktivitätskonzentration von Tritium in Wasserproben aus der Umwelt oder von tritiiertem Wasser ([3H]H2O) mithilfe eines Flüssigszintillationszählers fest. Die Auswahl des analytischen Verfahrens, ob mit oder ohne Destillation der Wasserprobe vor der Bestimmung, hängt vom Ziel der Messung sowie von den Eigenschaften der Probe ab. Bei der Direktmessung von Rohwasserproben mithilfe des Flüssigszintillationszählers muss das potenzielle Vorhandensein von Beta-Strahlen emittierenden Radionukliden berücksichtigt werden. Um bei Feststellung solcher Radionuklide Störungen mit diesen zu vermeiden, wird die Tritiumquantifizierung nach der Probenbehandlung durch Destillation durchgeführt. Drei Destillationsverfahren werden in den Anhängen B, D und E beschrieben. Dieses Verfahren eignet sich nicht für die Analyse von organisch gebundenem Tritium. Diese Bestimmung erfordert weitere chemische Aufarbeitung (wie eine chemische Oxidation oder Verbrennung). Unter geeigneten technischen Voraussetzungen kann die Nachweisgrenze bei 1 Bq l-1 liegen. Aktivitätskonzentrationen von Tritium unter 106 Bq l-1 können ohne Probenverdünnung bestimmt werden. Eine vorherige Anreicherung kann die Nachweisgrenze beträchtlich senken.

5.1 Deposits on heat transfer surfaces reduce efficiency of the heat exchanger affected. A method for easily determining the corrosion and fouling tendency of a particular water under heat transfer conditions will allow the evaluation of changes in the various system variables such as heat flux, flow velocity, metallurgy, cycles-of-concentration, and treatment schemes on heat exchanger performance. 1.1 This test method provides directions for fabricating and operating a test apparatus to simultaneously monitor the corrosion and fouling tendency of real and pilot cooling water systems under heat transfer conditions. 1.2 Interpretation of the results of this test method must be left to the investigator. Many variables are involved which may not be easily controlled or fully understood. Variations in design and operating conditions may produce results that are not comparable from unit to unit. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use.

4.1 Since the two tendencies are inseparable for a metal to corrode and for water and the materials it contains to promote or inhibit corrosion, the corrosiveness of a material or the corrosivity of water must be determined in relative, rather than absolute, terms. The tendency for a material to corrode is normally determined by measuring its rate of corrosion and comparing it with the corrosion rates of other materials in the same water environment. Conversely, the relative corrosivity of water may be determined by comparing the corrosion rate of a material in the water with the corrosion rates of the same material in other waters. Such tests are useful, for example, for evaluating the effects of corrosion inhibitors on the corrosivity of water. Although this test methods is intended to determine the corrosivity of water, it is equally useful for determining corrosiveness and corrosion rate of materials. Examples of systems in which this method may be used include but are not limited to open recirculating cooling water and closed chilled and hydronic heating systems. 1.1 This test method covers the determination of the corrosivity of water by evaluating pitting and by measuring the weight loss of metal specimens. Pitting is a form of localized corrosion: weight loss is a measure of the average corrosion rate. The rate of corrosion of a metal immersed in water is a function of the tendency for the metal to corrode and is also a function of the tendency for water and the materials it contains to promote (or inhibit) corrosion. 1.2 The test method employs flat, rectangular-shaped metal coupons which are mounted on pipe plugs and exposed to the water flowing in metal piping in municipal, building, and industrial water systems using a side stream corrosion specimen rack. 1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

This International 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 approximately 2 mg/l. No upper limit has been established. NOTE 1 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 factors. Results obtained with unstable samples need to be interpreted with caution. Floating oil and other immiscible organic liquids will interfere (see annex B). Samples containing more than approximately 1 000 mg/l of dissolved solids can require special treatment (see 8.6). NOTE 2 The result of the determination depends to some extent on the type of filter used, see 5.2. It is therefore necessary that the type of filter be specified. NOTE 3 The size distribution of particles in different water samples can vary widely. Therefore there is no correlation between results obtained with filters of different pore diameter, and no conversion factor can be given for the conversion of results obtained with one type of filter to another.
