Grūdėtosios atliekos, dumblas, dirvožemis, į dirvožemį panašios medžiagos ir nuosėdos. Išplovimas. Atitikties tyrimai nustatant išplovimą. 2 dalis. Vienpakopis partijos tyrimas, kai skysčio ir kietosios medžiagos santykis 10 L/kg, o medžiagos dalelių dydis mažesnis kaip 4 mm (dydį mažinant arba nemažinant)

This document in the series specifies a compliance test providing information on leaching of granular waste materials, sludges, soil, soil-like materials and sediments under the experimental conditions specified hereafter, and particularly a liquid to solid ratio of 10 L/kg dry matter. It applies to materials which have a particle size below 4 mm without or with size reduction. This document has been developed to investigate the leaching of inorganic and non-volatile organic substances from granular waste materials, sludges, soil, soil-like materials and sediments. It does not take into account the consequences of microbiological processes in organic degradable materials. The test procedure specified in this document produces an eluate which is subsequently characterized physically and chemically according to appropriate standard methods. This document includes two different procedures for eluate preparation prior to analysis, one procedure for non-volatile organic substances, inorganic substances and DOC and one for inorganic substances and DOC. When assessing only the leaching of inorganic substances and DOC, certain precautions are needed when assessing the leaching of organic substances can in some cases be omitted. This procedure cannot be applied to materials with a water content or such a water affinity that a good mixing of the solid with the predetermined quantity of liquid is not achievable. This procedure does not apply to materials reacting with the leachant, leading, for example, to excessive gas emission, a solidifying effect or an excessive heat release. In that case, the material can be wetted prior to carrying out the leaching test. This test cannot be used alone to determine the leaching behaviour of granular waste materials, sludges, soil, soil-like materials and sediments, as specified in EN 12920. This document does not address issues related to health and safety.

Vandens kokybė. Stroncis 90 ir stroncis 89. Tyrimo metodai naudojant blyksnių skystyje skaičiavimą arba proporcinį skaičiavimą (ISO/DIS 13160:2026)

Warning — Persons using this document should be familiar with normal laboratory practice. This document does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to determine the applicability of any other restrictions. Warning — It is absolutely essential that tests conducted according to this document be carried out by suitably trained staff. This document specifies methods to determine 90Sr and 89Sr by liquid scintillation counting (LSC) or proportional counting (PC) in supply water, drinking water, rainwater, surface and ground water, marine water, as well as cooling water, industrial water, domestic, and industrial wastewater after proper sampling, handling and test sample preparation. The detection limit depends on the sample volume, the instrument used, the sample counting time, the background count rate, the detection efficiency and the chemical yield. The method described in this document, using currently available LSC and PC instruments, has a detection limit of approximately 2 mBq·l−1 and 10 mBq·l−1 for 90Sr and 89Sr, respectively, for a volume of 2 l and a measuring time of 60 000 s, which is lower than the WHO criteria for safe consumption of drinking water (100 Bq·l−1 for 89Sr and 10 Bq·l−1 for 90Sr)[4]. The methods described in this document are applicable in the event of an emergency situation. When contamination contains fresh fission products, the contribution of 89Sr to the total amount of radioactive Sr is not negligible. This document provides test methods to determine the activity concentration of 90Sr in presence of 89Sr, and to determine the activity concentration of 90Sr in large volume of water sample (>50 L). The analysis of 90Sr and 89Sr adsorbed to suspended matter is not covered by this method. Filtration of the test sample and a chemical separation are required to separate and purify Sr from a test portion of the sample as the analysis of 90Sr and 89Sr adsorbed to suspended matter is not covered by this method. It is the user’s responsibility to ensure the validity of this test method selected for the water samples tested.
