Aplinkos apsaugos vadybos sistemos. Reikalavimai ir naudojimo gairės (ISO/FDIS 14001:2026)

This document specifies the requirements for an environmental management system that an organization can use to enhance its environmental performance. It is intended for use by an organization seeking to manage its environmental responsibilities in a systematic manner that contributes to the environmental pillar of sustainability. This document helps an organization to achieve the intended outcomes of its environmental management system, which provide value for the environment, the organization itself and interested parties. The intended outcomes of an environmental management system include: — enhancing environmental performance; — meeting compliance obligations; — achieving environmental objectives. This document is applicable to any organization, regardless of size, type and nature, and applies to the environmental aspects of its activities, products and services that the organization determines it can either control or influence considering a life cycle perspective. This document does not state specific environmental performance criteria. This document can be used in whole or in part to systematically improve environmental management. Claims of conformity to this document, however, are not acceptable unless all its requirements are incorporated into an organization’s environmental management system and fulfilled without exclusion.

Vandens kokybė. Mėginių ėmimas. 1 dalis. Nurodymai dėl mėginių ėmimo programų sudarymo ir mėginių ėmimo būdų (ISO/DIS 5667-1:2025)

This document sets out the general principles for, and provides guidance on, the design of sampling programmes and sampling techniques for all aspects of sampling of water (including waste waters, sludges, effluents, suspended solids and sediments). This document does not include detailed instructions for specific sampling instructions, which are covered in various other parts of the ISO 5667 series and in ISO 19458 [1].

Komentavimo iki data 2026-02-10

Vandens kokybė. Uranas. Tyrimo metodas skaičiuojant alfa dalelių blyksnius skystyje (ISO/DIS 13169:2025)

This document specifies the measurement method for the determination of total activity concentration of uranium isotopes in non-saline waters by extraction and liquid scintillation counting. This method covers the measurement of soluble uranium isotopes in water in activity concentrations between approximately 2·10−3 Bq/kg and 10 Bq/kg when analysing a 1 l test sample volume with a 60 000 s counting time with a typical alpha LSC instrument. The ratio 234U/238U can also be determined. This method has not been tested for the measurement of other uranium isotopes.

Vandens kokybė. Visuminis beta aktyvumas. Bandymo metodas naudojant storasluoksnį šaltinį (ISO/DIS 9697:2025)

This document specifies a test method for the determination of gross beta activity concentration in non-saline waters. The method covers non-volatile radionuclides with maximum beta energies of approximately 0,3 MeV or higher. Measurement of low energy beta emitters (e.g. 3H, 228Ra, 210Pb, 14C, 35S and 241Pu) and some gaseous or volatile radionuclides (e.g. radon and radioiodine) might not be included in the gross beta quantification using the test method described in this document. This test method is applicable to the analysis of raw and drinking waters. The range of application depends on the amount of total soluble salts in the water and on the performance characteristics (background count rate and counting efficiency) of the counter used. It is the laboratory's responsibility to ensure the suitability of this method for the water samples tested.

prEN ISO 9308-4 Viešoji apklausa

Komentavimo iki data 2026-01-27

Vandens kokybė. Žarninių lazdelių (Escherichia coli) ir koliforminių bakterijų skaičiavimas. 4 dalis. Žarninėms lazdelėms (Escherichia coli) taikomas membraninio filtravimo metodas, skirtas vandeniui, kuriame yra didelis foninių bakterijų kiekis

This document describes a highly specific method for the enumeration of Escherichia coli (E. coli) in water. The method is based on membrane filtration followed by culture at 44 °C on chromogenic agar medium containing an ingredient for the detection of the enzyme β-glucuronidase, and calculation of the number of target organisms in the sample[5,6,13]. Because of the high specificity of the method, this document is suitable for waters with high levels of background bacteria, such as surface waters including bathing water and wastewater provided that they contain little particulate or colloidal matter relative to the E. coli concentration. The method can be used for fresh water and, with an adaptation, for marine water. E. coli strains which do not grow at 44 °C and those that are β-glucuronidase negative, such as E. coli O157, will not be detected as E. coli by this method. This method is not applicable to the enumeration and detection of coliform bacteria other than E. coli.
