This International Standard specifies a protocol to identify ecotoxicological test specimens (mainly invertebrates and plants) to the species level, based on the DNA barcoding technique. This protocol can be used by laboratories performing DNA barcoding in order to standardise both the wet-lab and data analysis workflows as much as possible, and make them compliant with community standards and guidelines. It is not intended by this International Standard to specify one particular strain for each test method, but to accurately document the species/strain which was used. This International Standard does not aim at duplicating or replacing morphological-based species identifications. On the contrary, DNA barcoding is proposed as a complementary identification tool where morphology is inconclusive, or to diagnose cryptic species, in order to ensure that the results obtained from different ecotoxicological laboratories are referring to the same species or strain. This International Standard is applicable to identifications of immature forms which lack morphological diagnostic characters (eggs, larvae, juveniles), as well as the streamline identification of specimens collected in field monitoring studies, where large numbers of organisms from diverse taxa are classified.

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 interpretedwith 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.

This document specifies a chronic test method for evaluating the habitat function of soils and determining effects of soil contaminants and substances on the reproduction of Hypoaspis aculeifer by – mainly – alimentary uptake. This chronic test is applicable to soils and soil materials of unknown quality, e. g. from contaminated sites, amended soils, soils after remediation, industrial, agricultural or other sites under concern and waste materials (e. g. dredged material, municipal sludge from a wastewater treatment plant, composed material, or manure, especially those for possible land disposal). The test reflects the bioavailability of a mixture of contaminants in natural soils (contaminated site soils) to a species which represents a trophic level which is so far not covered by ISO. The reproduction (= number of juveniles) is the measured parameter of the test. It is not intended to use this test to replace the earthworm (ISO 11268-2) or Collembola reproduction tests (ISO 11267) since this species belongs not only to another trophic group but also to another taxonomic group (= mites; i.e. arachnids) than the other test species used so far. Effects of substances are assessed using a standard soil, preferably a defined artificial soil substrate. For contaminated soils, the effects are determined in the soil to be tested and in a control soil. According to the objective of the study, the control and dilution substrate (dilution series of contaminated soil) are either an uncontaminated soil comparable to the soil to be tested (reference soil) or a standard soil (e. g. artificial soil). This document provides information how to use this method for testing substances under temperate conditions. This document is not applicable to substances for which the air/soil partition coefficient is greater than one, or to substances with vapour pressure exceeding 300 Pa at 25°C.

This document specifies a method for the determination of the cation exchange capacity (CEC) at the pH of the soil and for the determination of the content of exchangeable sodium, potassium, calcium and magnesium in soil. This document is applicable to all types of air-dried soil samples; pretreatment according to ISO 11464 is recommended.

This document specifies a method for the determination of exchangeable acidity in barium chloride extracts of soil samples obtained according to ISO 11260. The procedure described herein mainly concerns the determination of total exchangeable acidity by means of a fixed pH end point titration. Two additional and optional procedures are given, describing respectively, determinations of free H+ acidity and aluminium in the extracts. This document is applicable to all types of air dry soil samples.

This document specifies a method for the determination of total organic carbon (TOC), dissolved organic carbon (DOC), for the determination of dissolved and particular bound nitrogen (TNb) and dissolved bound nitrogen (DNb) in the form of free ammonia, ammonium, nitrite, nitrate and organic compounds capable of conversion to nitrogen oxides under the conditions described. The procedure is carried out instrumentally. The method is applicable for water samples (e.g. drinking water, raw water, ground water, surface water, sea water or waste water). The method allows a determination of TOC/DOC = 1 mg/l and TNb/DNb = 1 mg/l. The upper working range is restricted by instrument dependant conditions (e.g. injection volume). Higher concentrations may be determined after appropriate dilution of the sample. Cyanide, cyanate and particles of elemental carbon (soot), when present in the sample, can be determined together with the organic carbon. Volatile (VOC) or purgeable organic carbon, or dissolved nitrogen gas (N2) are not determined under the conditions described by this method.

This part of ISO 23753 specifies a method for determining activity of dehydrogenase in soil, using 2-(4-iodophenyl)-3-(4-nitrophenyl)-5-phenyltetrazolium chloride (INT).[1-5] As the INT reduction is less sensitive to O2, the method is more reproducible than the TTC-method described in ISO 23753-1.
