Vandens kokybė. Technecis 99. 2 dalis. Tyrimo metodas taikant induktyviai sužadintos plazmos masių spektrometriją (ICP-MS) (ISO/DIS 22125-2:2026)

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. Warning — It is absolutely essential that tests conducted in accordance with this document be carried out by suitably qualified staff. This document specifies methods to determine 99Tc by inductively coupled plasma mass spectrometry (ICPMS) 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 background count rate, the detection efficiency, the counting time, and the chemical yield. The detection limit of the methods described in this document, using currently available ICP-MS instrumentation, is approximately 0,2 ng·l−1 to 0,5 ng·l−1 (0,1 Bq·l−1 to 0,3 Bq·l−1), which is much lower than the WHO criteria for safe consumption of drinking water (100 Bq·l−1)[4]. The methods presented in this document are not intended for the determination of ultratrace amount of 99Tc. The methods described in this document are applicable in the event of an emergency situation, but not if 99mTc is present at quantities that could cause interference. Filtration of the test sample is necessary for the methods described in this document if suspended solids are present. The analysis of 99Tc adsorbed to suspended matter is not covered by this method. The analysis of the insoluble fraction requires a mineralization step that is not covered by this document. In this case, the measurement is made on the different phases obtained. It is the user’s responsibility to ensure the validity of this test method for the water samples tested.

Informacijos mainai tarp BIM ir GIS. 2 dalis. Duomenų mainų palengvinimas naudojant metaduomenis (ISO/DIS 23143-2:2026)

The scope of this project is to provide guidelines for information exchange between BIM and GIS. As part of a series of proposed international standards for BIM-GIS information exchange, Part 02: Facilitating data exchange through metadata will aim to solve metadata issues to support bidirectional GIS/BIM information exchange and suggest technical requirements based on use case scenarios. Metadata give great opportunities to find, evaluate and manage relevant information for the bidirectional information exchange. To ensure the interoperability between GIS and BIM information models, it is critical for one domain experts to understand the metadata generated from the other domain and vice versa. The work will review existing methodologies and research with regard to bidirectional GIS/BIM information exchange, especially in terms of metadata and item registration. It will provide a use case scenario to give a certain context of bidirectional exchange of metadata. The use case will also provide the context within which the interaction that needs to be taken place between GIS and BIM model experts. With the use of the use case scenario, the process of properly generating metadata for each domain to ensure the bidirectional exchange can be identified. It will then list the technical requirements to support the process and provide a guideline to follow.

Komentavimo iki data 2026-10-08

Potencialiai sprogiose atmosferose naudojamų ventiliatorių projektavimas

1.1 This document specifies the constructional requirements for fans constructed to Group II G (of explosion groups IIA, IIB and hydrogen) categories 1, 2 and 3, and Group II D categories 2 and 3, intended for use in explosive atmospheres. NOTE 1 Operation conditions for the different categories of fans used in this document are defined in Clause 4. 1.3 This document specifies requirements for design, construction, testing and marking of complete fan units intended for use in potentially explosive atmospheres in air containing gas, vapour, mist and/or dusts. Such atmospheres can exist inside (the conveyed atmosphere (flammable or not)), outside, or inside and outside of the fan. This document covers mechanical equipment, in particular fans. The “type of protection” as specified in EN ISO 80079 37:2016 is constructional safety. 1.4 This document is applicable to fans working in ambient atmospheres and with normal atmospheric conditions at the inlet, having — absolute pressures ranging from 0,8 bar to 1,1 bar, — and temperatures ranging from −20 °C to +60 °C, — and maximum volume fraction of 21 % oxygen content, — and an aerodynamic energy increase of less than 25 kJ/kg. NOTE 1 25 kJ/kg is equivalent to 30 kPa at inlet density of 1,2 kg/m3. This document can also be helpful for the design, construction, testing and marking of fans intended for use in atmospheres outside the validity range stated above or in cases where other material pairings need to be used. In this case, the ignition risk assessment, ignition protection provided, additional testing (if necessary), manufacturer's marking, technical documentation and instructions to the user, clearly demonstrate and indicate the equipment's suitability for the conditions the fan can encounter. NOTE 2 Temperatures below −20 °C can be considered. Material suitability can require specific evaluation for these temperatures. With lower temperature the explosion pressure increases, which leads to increased test pressures (see A.3) and can require specific testing. Although the standard atmospheric conditions in EN ISO 80079 36:2016 give a temperature range for the atmosphere of −20 °C to +60 °C the normal ambient temperature range for the equipment is −20 °C to +40 °C unless otherwise specified and marked. 1.5 This document does not apply to: — group I fans (fans for mining); — explosion group IIC (other than hydrogen); — category 1D fans; — cooling fans or impellers on rotating electrical machines; — cooling fans or impellers on internal combustion engines, vehicles or electric motors. NOTE 3 Measures for category 1D fans are given in EN 1127 1:2019. NOTE 4 Measures for explosion group IIC (other than hydrogen) are given in EN 1127 1:2019. NOTE 5 Measures for explosion group I are given in EN ISO/IEC 80079 38:2016 and EN 1127 2:2014.
